Jan 30, 2026
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
Error Code | Common Meaning | Possible Cause | Quick Fix |
|---|---|---|---|
E1 / F1 / IE / 4C | Water fill timeout | Closed tap, clogged inlet filter, or kinked hose | Open the water tap fully, clean the filter screen, or straighten hoses |
E2 / F2 / 5C / OE / 5E | Drainage error | Clogged pump filter, blocked drain hose, or improper hose height | Clear debris from the drain filter and ensure the hose is not kinked |
E3 / UE / UB / dc | Unbalanced load | Laundry is unevenly distributed or machine is not level | Redistribute clothes evenly and adjust the leveling feet |
E4 / dE / LE / dL | Door/Lock error | Door is not closed properly or latch is obstructed/faulty | Close the door firmly and check for trapped clothing or obstructions |

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:
Use the right detergent: Always use High-Efficiency (HE) detergent if your machine requires it, and never exceed the recommended amount.
Clean the filters: Check and clean the drain pump filter and the water inlet screens at least once a month to prevent clogs.
Balance your loads: Avoid washing a single heavy item alone; add a few towels to help balance the drum during the spin cycle.
Inspect the hoses: Regularly check the hoses at the back of the machine for any signs of wear, leaks, or sharp bends.
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".
👉 Front-Loading Washing Machine Stinks? Here Are the Reasons and How to Clear Up the Smell
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.

Many homeowners accidentally shorten the lifespan of their new investment by skipping key steps during setup and early use.
A new appliance is a major financial commitment. To help you get the most out of your purchase and ensure your appliances last for years, you should not wait for a problem to occur.
This comprehensive guide covers the most frequent mistakes made by homeowners and provides the exact actions you should take to avoid them.
5 Appliance Mistakes to Avoid So Your New Appliances Last Longer
1. Skipping the Manufacturer’s Manual
Modern appliances are complex machines with advanced sensors and specific installation needs. Many homeowners assume they already know how to use a new appliance and toss the manual aside. This can cause safety problems or cancel your warranty.
Before first use, scan the manual for any setup steps that must be done in order, including removal of packaging or shipping parts, correct connection requirements, and any recommended “first run” or calibration steps. Keep the manual in an easy-to-find place so you can quickly check error codes, settings, and care instructions later instead of guessing or relying on random online advice.

2. Poor Installation and Leveling
When appliances are not installed properly, they can shake, leak, make noise, and wear out sooner than expected.
Before you use the appliance, make sure it sits steady and level. Use a simple bubble level and make small tweaks if needed. This can cut down on shaking and wear over time.
Next, check every hookup and connection. Make sure each one is tight and secure. Look for hoses or cords that are kinked, pinched, or pulled too tight.
If the install involves gas, high voltage, or plumbing, hire a certified professional. It helps prevent leaks, damage, and other safety problems.
3. Overloading and Misusing the Appliance
Just because an appliance looks roomy doesn’t mean you should fill it to the max. Overloading, or using it the wrong way, can block normal operation and put extra strain on internal parts.
Stick to the capacity and use limits from the manufacturer, even if it seems like it can handle more. Load items so they have space to move, and so air or water can flow as needed. Use the recommended products and settings, and don’t use more than required. Too much product can cause buildup and lower performance over time.
4. Skipping Regular Maintenance from Day One
Many homeowners think a new appliance needs no care. But dust, residue, and debris can build up right away. Without upkeep, odors or performance issues can show up within weeks.
Start basic maintenance early, not after a problem starts. Keep a simple cleaning routine on a set schedule, with extra attention on spots that hold moisture or grime. Wipe seals and contact points to stop buildup. Check filters, traps, and vents often so air flow and drainage stay clear. Small monthly habits can help prevent smells, clogs, and early wear.
5. Forgetting Warranty Registration
With a busy schedule, it’s easy to forget warranty registration. But if you skip it, you may face delays or lose coverage when you need a repair.
Register the appliance as soon as it’s installed so the purchase is linked to your name and contact details. Keep the model and serial number, proof of purchase, and warranty info together in one spot. That way, you can find everything fast if you need service.
If you’re thinking about an extended plan, read what it really covers. Then decide based on likely repair costs, the appliance’s complexity, and how often you use it.
Common Home Appliance Issues and How to Solve Them
If your new appliance is not working as expected, try these steps before calling for service:
Problem | Potential Solution |
|---|---|
Unpleasant Odors | Allow airflow after use and clean internal surfaces regularly |
Poor Performance | Ensure nothing is blocking moving parts or airflow paths. |
Excess Moisture or Frost | Check door seals and make sure they close tightly. |
Appliance Won’t Start | Check the circuit breaker and confirm it is on a dedicated circuit if required. |
