Common Samsung Washer Error Codes We See

Out of all the codes above, the following are among the Samsung washer error codes our technicians encounter regularly. Here’s the detailed breakdown of each one.

1. Error Code 4C / 4E – Water Supply Error

What’s happening: Your washer can’t get water. It’s trying to fill the drum, but water either isn’t arriving or isn’t arriving fast enough. The washer waits, tries again, then throws the code and stops.

What to check before calling anyone:

1. Check that both hot and cold water valves behind the washer are fully open. This is one of the common causes, and sometimes a valve has simply been bumped or partially closed.
2. Inspect the water supply hoses for kinks or sharp bends. Pull the washer out slightly and check.
3. Clean the inlet filter screens. Where the hoses connect to the back of the washer, there are small mesh screens that catch debris. Turn off the water supply and disconnect the hoses before carefully cleaning the screens according to the instructions for your model.
4. Make sure your home’s water supply is running normally. Try a faucet nearby.

When to call a pro: If the valves are open, the hoses and inlet screens are clear, and the code still appears, there may be a problem with the water inlet system, valve, wiring, sensor, or another related component. Further diagnosis may be needed before replacing parts. Our washer repair technicians regularly diagnose Samsung water-supply problems and carry commonly used parts on their service vehicles.

2. Error Code 5C / 5E – Drain Error

What’s happening: The washer finished washing but can’t pump the water out. Your clothes may be sitting in water and the door may remain locked until the water is drained.

What to check:

1. Clean the drain filter. This is one of the most common things to check. On many Samsung front-load washers, there’s a small access panel at the bottom-front of the machine. Follow the instructions for your model before opening the filter, and have towels or a shallow container ready because water may come out. Coins, bobby pins, small items, and other debris can collect in the filter.
2. Check the drain hose at the back of the washer. Make sure it’s not kinked and that the standpipe it drains into isn’t clogged.
3. After clearing an accessible blockage, follow the instructions for your model to test whether the washer drains normally.

When to call a pro: If the filter and drain hose are clear but the washer still cannot drain, the drain pump or another part of the drainage system may need to be inspected. We see situations where small objects such as coins or pieces of underwire get past the filter and interfere with or damage the pump impeller. If the pump or another internal component has failed, professional diagnosis can determine the appropriate repair.

Vancouver condo tip: If you’re in a high-rise or stacked townhome and the drain hose connects to a standpipe, a problem with the building’s drainage or standpipe setup can sometimes contribute to drainage problems at the washer. If other units are experiencing drainage problems as well, check with your strata or property manager.

3. Error Code UE / UB – Unbalanced Load

What’s happening: The washer tried to spin but detected that the load is uneven. It may stop or attempt to redistribute the load to reduce excessive vibration during the spin cycle. This is often a load-balance issue rather than a mechanical failure.

How to fix it:

• Open the door and redistribute the clothes evenly around the drum. A heavy towel or other item bunched up on one side can cause an imbalance.
• If you’re washing one heavy or bulky item, follow Samsung’s loading recommendations for your specific washer.
• Make sure the washer itself is level. If the machine rocks back and forth when you push on it, the leveling feet may need adjustment.
• Avoid overloading the washer and follow the load recommendations for your model.

When to call a pro: If the code appears repeatedly with normal, balanced loads and the washer is properly levelled, suspension components or another mechanical issue may need to be inspected. Our technicians regularly diagnose vibration and suspension problems in Samsung washers across Metro Vancouver.

4. Error Code dC / dE – Door Error

What’s happening: The washer is detecting that the door isn’t properly closed or locked. The washer will not begin or continue certain operations unless the control confirms that the door is securely locked.

What to check:

• Make sure the door is fully closed. Push it firmly until it latches.
• Check for clothing or other items caught between the door and gasket that could prevent the door from closing properly.
• Inspect the accessible area around the door latch for visible damage or debris.

When to call a pro: If the door closes properly but the code persists, there may be a problem with the door-lock mechanism, wiring, or another related component. Door-lock problems are something our technicians encounter regularly on Samsung washers. Professional diagnosis can determine whether the lock assembly or another component is causing the error.

5. Error Code SUd / 5Ud – Excessive Suds

What’s happening: The washer has detected excessive suds in the drum and may pause or extend the cycle while the suds dissipate. This is often related to detergent type or quantity rather than a mechanical malfunction.

How to fix it and prevent it:

• Use HE (High Efficiency) detergent. Use detergent that is appropriate for your Samsung high-efficiency washer.
• Use the appropriate amount of HE detergent for your washer, load size, water conditions, and detergent concentration. Follow the washer and detergent manufacturer’s dosing instructions.
• If excessive detergent or residue has built up, follow Samsung’s cleaning instructions for your specific washer model before adding more detergent.

When to call a pro: A one-time SUd/5Ud code can often be resolved by correcting detergent use. If the code repeatedly returns despite using the correct HE detergent and amount, further diagnosis may be needed.
