Washing Machine Won’t Drain: Causes, Symptoms, and How to Fix

Your washing machine suddenly stops and starts flashing a strange code like "F21" or "OE." 

Why?

Or, what are those codes?

These codes are your machine’s way of telling you exactly what is wrong.

Most washer error codes are just warnings, and you can fix these problems yourself, like the door being locked, an unbalanced load, or low water pressure.

This guide will help you understand those cryptic signals and get your laundry day back on track—or know when to call for a repair based on the error codes.

What Are Error Codes in Washers?

Error codes are alphanumeric messages that appear on your washing machine's digital display. On older models, these might show up as a specific pattern of blinking lights or symbols. Each code acts as a diagnostic tool triggered by internal sensors when the machine detects an anomaly during a cycle.

These systems are designed to protect your washer appliance from further damage by stopping the operation when a problem occurs.

All Washer Error Codes and Their Meanings, and Fixes

Common Error Code Categories in Washers

Washing machine malfunctions generally fall into a few main categories regardless of the brand you own. Understanding these categories can help you narrow down where the problem lies.

Drainage and Pump Issues

Drainage errors are some of the most frequent problems homeowners face. They are often represented by codes like E2, F21, 5E, or OE. These codes mean the machine is taking too long to drain or cannot remove water at all. The primary cause is usually a blockage in the drain pump filter caused by lint, coins, or small items like socks. You should also check the drain hose for any kinks or verify it is installed at the correct height.

Water Supply and Inlet Problems

If your machine is not filling with water or filling too slowly, you will see codes like E1, 4E, IE, or FH. This often happens because the water supply valves are not fully open. Another common cause is a clogged inlet filter screen, which can be cleaned with a small brush. In some cases, low house water pressure or a kinked intake hose prevents the machine from detecting water.

Unbalanced Loads and Drum Movement

Codes such as E3, UE, UB, or dc signal that the drum is not balanced. This happens when heavy items like blankets or rugs clump together on one side during the spin cycle. When this occurs, the machine may stop or shake excessively to prevent damage. To fix this, simply pause the cycle and manually redistribute the laundry inside the drum.

Door Lock and Safety Failures

Safety is a priority for modern washers, so they will not start if they think the door is open. Codes like dL, dE, dL, or F01 point to door lock issues. Sometimes the fix is as simple as removing a piece of clothing caught in the seal. Other times, the mechanical latch or the electronic sensor might be faulty and require a replacement.

Heating and Temperature Errors

Temperature-related codes like HE, E5, or F03 indicate that the water is not reaching the right temperature. This is very common in front-loading machines that heat their own water. A faulty heating element or a malfunctioning thermostat is usually the culprit. You can test the heating element for continuity with a multimeter if you feel comfortable doing so.

Motor and Electrical Malfunctions

Electrical issues are signaled by codes like OC, CE, or F01. These can be caused by power surges or malfunctions in the main control board. A simple reset—unplugging the machine for 5 to 10 minutes—can sometimes clear temporary electronic glitches. If the motor itself is overloaded or jammed, you might see an LE code, suggesting you should reduce the load size.

Excessive Suds

If you see Sud or Sd, it means there is too much foam in the drum. This is almost always caused by using too much detergent or the wrong type of soap. High-efficiency (HE) machines are particularly sensitive to detergent amounts. When this happens, the machine may run a special rinse cycle to clear the foam, and you should use less soap in the future.

Brand-Specific Washing Machine Error Code Examples

While many codes are similar, different manufacturers use their own unique languages.

• Samsung: They often use 4C for water supply, DC for unbalanced loads, and UB for spinning issues. They also use 5E specifically for drainage problems.

• LG: You will frequently see IE for inlet errors and OE for drainage errors. CL is a very common non-fault code for the child lock.

• Whirlpool: Their codes usually start with "F" and "E," such as F02 for drain issues or F06 for motor faults. F01 typically signals a main control board failure.

• Bosch: They use codes like E15 to indicate a water leak has been detected in the base of the machine. E18 or F18 is their standard code for a drain pump timeout.

• Beko: These machines often show EHO for a door open error or EFO for a water filling error.

• Miele: You might see F11 for drainage difficulties or F16 if the machine detects too much detergent.

Preventive Measures to Avoid Errors

Most error codes can be prevented with a little bit of regular care. Following these simple steps will help your machine run smoothly and last longer:

1. Use the right detergent: Always use High-Efficiency (HE) detergent if your machine requires it, and never exceed the recommended amount.

2. Clean the filters: Check and clean the drain pump filter and the water inlet screens at least once a month to prevent clogs.

3. Balance your loads: Avoid washing a single heavy item alone; add a few towels to help balance the drum during the spin cycle.

4. Inspect the hoses: Regularly check the hoses at the back of the machine for any signs of wear, leaks, or sharp bends.

5. Don't overload: Stick to the load capacity recommended in your manual to avoid straining the motor and belt.

When to Call a Professional?

While over 50% of error codes can be resolved with basic DIY troubleshooting, some situations require an expert. You should call a professional technician if:

• Errors are persistent: If a code keeps coming back after you have tried the recommended fixes, there may be a deeper electrical problem.

• Internal hardware fails: Problems involving the motor, the main control board, or internal wiring are complex and can be dangerous to fix without training.

• Water leaks: Serious leaks from the internal tub or major valves can cause water damage to your home if not handled correctly.

• Under warranty: If your machine is still under warranty, you should contact the manufacturer's service center first to avoid voiding your coverage.

We all want our laundry to come out smelling fresh and looking spotless. It is natural to think that if your clothes are extra dirty, adding a little more soap will do a better job.

However, the truth might surprise you. Using too much detergent, or using the wrong kind, can lead to expensive repairs and ruined wardrobes.

Can Laundry Detergent Damage a Washing Machine?

Yes, laundry detergent can absolutely damage your washing machine if it is not used correctly. When you use too much detergent, it creates an overflow of suds. These bubbly suds can get into pipes and hoses, leading to clogs that prevent the machine from draining properly.

One of the most serious issues involves a part called the "drum spider" or aluminum support. Excess suds can reach this support and cause it to rust. Because the spider stabilizes the drum, a rusty or damaged one forces the motor to work much harder to compensate, which can lead to a total motor failure over time.

Additionally, detergent residue traps moisture, creating a breeding ground for mold and mildew in the outer drum and rubber gaskets, which is why many machines develop a foul, musty smell.

Can Too Much Detergent Ruin Clothes?

Ironically, using extra detergent often makes your clothes dirtier. Too many suds create a slippery layer on the fabric that prevents the friction needed to rub off stains. Instead of being washed away, dirt and bacteria get trapped in the excess soap and settle back into the fibers.

Over time, this build-up can ruin your favorite outfits in several ways:

• Stiff fabrics: Clothes may feel hard, stiff, or "greasy" to the touch.

• Discoloration: You might notice white spots, streaks, or a dingy, faded appearance caused by a film of residue.

• Skin irritation: Detergent trapped in the fibers can cause rashes, itchiness, or allergic reactions like contact dermatitis.

• Odors: Odor-causing bacteria can linger in the soap film, especially on synthetic exercise gear, making clothes smell musky even after they are "clean".

Can You Put Detergent in the Washing Machine?

It is perfectly okay—and necessary—to put detergent in your washing machine, but how you do it matters. Most modern machines, especially front-loaders and high-efficiency (HE) models, are designed to work with very small amounts of concentrated soap. For a standard load, you may only need one to two tablespoons of detergent.

The best practice is to use the detergent dispenser tray. The machine is programmed to flush this tray with water at the right time, mixing the soap thoroughly before it hits your clothes. If you prefer to put detergent directly into the drum, it is best to add it before the laundry. This ensures it mixes with the water immediately and prevents the concentrated dyes in some soaps from staining your clothes.

By measuring your soap carefully and choosing the right type—such as HE detergent for HE machines—you can keep your appliance running smoothly for years while ensuring your clothes stay soft and bright.

Powder vs Liquid Detergent: Which One Should You Use?

Choosing between powder and liquid detergent depends on your washer, water temperature, and stain type.

Pick by machine

• Front-load/HE washers: Use HE detergent (powder or liquid) to avoid extra suds and residue.

• Top-load washers: Either type works; HE is still a good choice for newer models.

When liquid is better

• Dissolves well in cold or hot water

• Great for pre-treating stains

• Less likely to leave residue on dark clothes

• Easier to over-pour, so measure carefully

When powder is better

• Strong for mud and heavy dirt

• Can work well in hard water (often with a booster)

• May leave white flakes in cold washes and can clump if the drawer is damp

Bottom line: Use the right dose. Too much of either can cause buildup, rinsing issues, and odors.

Does Liquid Detergent Damage Washing Machines?

Liquid detergent won’t damage your washing machine by itself. But using too much of it, or using the wrong kind like non-HE detergent in an HE washer can cause problems. Extra soap can leave buildup, create mold and bad odors, and clog the drain. Over time, this can strain the pump and motor and lead to costly damage.

What Can Ruin a Washing Machine?

While detergent is a major factor, several other habits can ruin your appliance. Overloading the machine is one of the most common mistakes; it puts extreme stress on the motor and prevents clothes from moving freely.

Neglecting regular maintenance can also lead to a breakdown. For example, washing machine hoses should be inspected monthly for cracks or leaks and replaced every three to five years to prevent water damage. Clogged lint filters and drainage holes in the door gasket can also cause the machine to malfunction or leak. Even failing to leave the door open between cycles can ruin the machine’s freshness by encouraging mold growth.

How to Tell If Your Machine Has Detergent Buildup?

Detergent buildup often shows up first as sticky residue or a musty smell in the dispenser, drum, or rubber door seal. You may also notice too many suds during the wash or soap bubbles left on the door after the cycle ends. On laundry, buildup can leave clothes stiff, scratchy, spotty, or still smelly even after washing. If buildup gets worse, the washer may run longer, make odd noises, or leak because it can’t rinse properly.

Need an inspection or repair for your washer?

If your clothes still smell, you see residue in the drum or dispenser, or your washer is leaking or running longer than normal, the problem may be more than too much detergent. It could be buildup in the drain system, a clogged filter, a worn door seal, or a pump issue. To prevent mold, poor cleaning, and costly damage, it’s best to have a pro take a look.

Your refrigerator is likely the most hardworking appliance in your home, running 24 hours a day, 365 days a year to keep your food safe and fresh. While it usually sits quietly in the corner, a breakdown can turn your life upside down in just a few hours, leading to spoiled milk, ruined produce, and a very expensive mess. 

Because modern refrigerators are complex machines with delicate sensors and intricate cooling systems, they require a little bit of regular maintenance to stay at peak performance.

By spending just a few minutes every month on basic refrigerator maintenance, you can save money on energy bills, extend the lifespan of your appliance, and avoid the stress of sudden breakdowns.

Here is a comprehensive guide on how to treat your refrigerator like the kitchen hero it is.

Tips to Take Care of Your Refrigerator

1. Set the Right Refrigerator Temperature

Start with temperature settings, because they affect both food safety and energy efficiency. Keep your refrigerator at 4°C (37°F–40°F) and your freezer at -18°C (0°F). If the temperature is too low, your fridge wastes electricity. If it’s too high, bacteria can grow and food spoils faster.

If your fridge has a basic dial and you’re unsure whether it’s accurate, a small refrigerator thermometer can help you confirm the real temperature.

2. Keep Airflow Clear Inside the Fridge

Cold air must move freely to cool every shelf evenly. When vents are blocked, your refrigerator has to work harder to maintain the same temperature, which can lead to uneven cooling and higher energy bills.

Avoid pushing large items directly against the back wall or in front of airflow vents. Even simple changes—like leaving a little space between containers—can improve circulation and prevent warm spots.

3. Leave Space Behind the Refrigerator

Your refrigerator releases heat as it runs, and it needs room to “breathe.” If it’s pressed tightly against the wall, heat can build up and stress the cooling system.

Leave at least 2–3 cm (about 1 inch) between the back of the refrigerator and the wall. Keeping this area clear helps the appliance release heat efficiently and reduces the risk of overheating.

4. Keep the Refrigerator Level So the Door Seals Properly

A fridge that leans slightly can cause the door to close poorly, which lets cold air leak out. Even a small gap can increase power usage and cause temperature problems.

You can check the level by placing a simple level tool on a shelf inside the fridge. If needed, adjust the feet at the bottom until the refrigerator sits evenly. A level fridge usually runs quieter too, because the door closes more naturally.

5. Clean and Protect the Door Seal (Gasket)

The door gasket is the rubber seal around the door. It keeps cold air in and warm air out, which makes it a key part of proper fridge maintenance. When the gasket is dirty, cracked, or loose, your refrigerator may run longer than it should, and your electricity bill may climb.

A quick way to test the seal is the coin test. Close the refrigerator door on a coin and gently pull. If the coin slides out easily, the gasket may not be sealing well. To keep the seal working properly, wipe it weekly using warm water and mild soap, then dry it. This prevents sticky buildup and helps the rubber stay flexible.

Also, try not to leave the door open while deciding what to eat. Every extra second lets cold air escape and forces the appliance to work harder to cool down again.

6. Clean the Condenser Coils Twice a Year

If you want one “high impact” task for refrigerator care, this is it. Condenser coils release heat during cooling, and when they get covered in dust or pet hair, your fridge loses efficiency. That makes the compressor work harder, which can shorten the appliance’s lifespan.

Most coils are located on the back or bottom of the refrigerator. Unplug the unit, then use a vacuum or coil brush to remove the buildup. Doing this twice a year is a simple way to improve performance and reduce energy use.

7. Defrost the Freezer When Ice Builds Up

If your freezer is not frost-free, ice buildup can block airflow and reduce cooling power. When the frost reaches around 7 mm (¼ inch), it’s time to defrost your freezer.

Turn off the freezer, move food into a cooler, and let the ice melt naturally. Never use sharp metal tools to scrape ice because you can damage the interior walls or puncture something important. A plastic scraper or a wooden spoon is much safer.

8. Store Food in a Way That Helps Your Fridge Work Better

Smart food storage supports better airflow and reduces moisture inside the fridge. This improves cooling consistency and helps prevent smells from spreading.

Try to keep leftovers in sealed containers, and cover foods that release strong odors. This reduces humidity and keeps the refrigerator interior cleaner, which helps your appliance maintain stable temperature more easily.

9. Protect Your Refrigerator from Power Surges

Modern refrigerators rely on electronic control boards, and sudden voltage spikes can cause expensive damage. A good surge protector designed for appliances can prevent unexpected failures and protect your investment.

This is especially helpful in areas with unstable power or frequent outages.

10. Follow the 24-Hour Rule After Moving a Refrigerator

If you just transported a refrigerator, don’t plug it in immediately. During movement, the compressor oil can shift away from where it needs to be. Let the unit stand upright for 24 hours before turning it on, so everything settles correctly.

This one step can prevent long-term compressor issues.

11. Register Your Warranty for Faster Support

Warranty registration takes only a few minutes, but it can save you stress later. Register your fridge online and keep your model and serial number stored somewhere easy to find. If there’s ever a recall or major repair issue, you’ll be ready, and support is usually faster.

When to Call a Professional for a Refrigerator?

While you can safely handle cleaning and filter replacements, some issues are dangerous to tackle alone. You should call a certified technician for refrigerator inspection or repair if you notice:

1. Electrical issues: Visible sparks, a burning smell, or frequently tripped breakers.

2. Unusual noises: Loud grinding, vibrating, or clicking sounds.

3. Leaks: Standing water or refrigerant leaks near the unit.

4. Cooling failure: If the compressor won't start or the temperature remains inconsistent despite cleaning the coils.

Hiring a professional ensures an accurate diagnosis, protects your manufacturer's warranty, and—most importantly—keeps you safe from high-voltage electricity and pressurized gases

Need an inspection or repair for your refrigerator?

If your fridge isn’t cooling properly, is leaking water, or keeps making loud noises, the issue may be more than a simple setting or dirty coil. It could be a failing compressor, a faulty thermostat, a clogged drain line, or a bad door seal. To avoid spoiled food and bigger repair costs, it’s best to have a pro check it.
