Samsung dishwashers are generally reliable, but like any machine they develop specific failure patterns. Knowing what to look for — and what the error codes mean — helps you troubleshoot faster and decide when to DIY versus when to call a technician.

Samsung dishwasher error codes
Samsung displays codes on the front panel when it detects a fault. Key codes and what they mean:
- 1E / IE: Water level sensor fault. The sensor may be dirty, damaged, or the wiring harness is loose.
- 3C / 3E: Motor fault. The wash motor isn’t running properly. Could be the motor itself or the control board relay.
- 4C / 4E: Water supply error. The machine isn’t getting water. Check supply valves, inlet hose, and the screen filters in the hose.
- 5C / 5E: Drain error. Most commonly a clogged filter or kinked drain hose.
- 7E: Door latch error. The door isn’t fully latching — check for obstructions and confirm the latch clicks.
- bE2 / 6E: Button stuck error. A control panel button is registering as continuously pressed. Try resetting the machine.
- LC / LE: Leak detected. The flood sensor at the base of the machine has activated. Look for any visible leaking and let the machine dry out before resetting.
- OC / 0C: Water overfill — the machine filled more than expected. Check the water inlet valve.
How to reset a Samsung dishwasher
For most error codes, a reset clears the error. To reset:
- Press the Start button and hold for 3 to 5 seconds, or
- Turn off the machine, unplug from the wall (or turn off the circuit breaker), wait 5 minutes, then restore power.
If the error code returns immediately after reset, the underlying problem is still active and needs addressing.
Samsung dishwasher not draining (5C / 5E)
Drainage failure is the most common Samsung dishwasher complaint. Typical causes in order of likelihood:
- Clogged filter: Twist off the filter in the center of the floor and clean it under warm water with a soft brush.
- Kinked drain hose: Pull the machine forward and check the hose routing behind it.
- Garbage disposal connection: If connected to a garbage disposal and the disposal is new, check that the knockout plug was removed from the disposal’s dishwasher port.
- Clogged pump: After clearing the filter, reach into the sump area and check for debris around the pump impeller.
- Failed drain pump motor: If none of the above applies and you hear no sound from the pump during the drain phase, the motor has failed.
Samsung dishwasher not cleaning dishes properly
If dishes come out with food residue or are poorly cleaned:
- Clean the filter (see above)
- Remove and clean the spray arms — poke each nozzle hole clear with a toothpick
- Verify the detergent dispenser is opening during the cycle
- Check water temperature — Samsung dishwashers need water at 50°C or higher for effective cleaning. If your hot water heater is set low or the supply line runs cold before reaching the dishwasher, cleaning performance drops.
- Confirm you’re using HE dishwasher detergent in the right amount
Samsung dishwasher not drying
Samsung dishwashers use a condensation drying method — no drying element in most models. They dry by condensing steam on the cooler stainless steel tub walls. This works well but has limitations:
- Plastic items dry poorly with condensation drying — this is normal. Use a towel on plastics if this bothers you.
- Rinse aid is critical for condensation drying. If the rinse aid dispenser is empty, drying performance drops significantly.
- The Auto Open door feature (on some Samsung models) opens the door slightly at the end of the cycle to let steam escape — if this is disabled, drying will be worse. Enable it in the settings if your model has it.
Some Samsung dishwashers (particularly newer DW80 series models) have a Zone Booster or Heated dry option — confirm these are enabled.
Samsung dishwasher door latch problems
Samsung dishwasher door latches wear over time. Signs of a failing latch: the door feels loose, the machine won’t start (it’s waiting for a confirmed door signal), or the 7E error appears.
Check first: look at the door latch area and the strike plate for visible damage or misalignment. Sometimes just pressing firmly on the door until it clicks resolves an intermittent latch problem. If the latch mechanism is physically broken, the assembly needs replacement — it’s behind the inner door panel, a 30-minute job on most Samsung models.
Samsung dishwasher leaking water
Samsung LC or LE codes indicate the flood sensor has activated. Common leak sources:
- Door seal (gasket) cracked or lifted out of its channel
- Spray arm hitting a tall item and directing water at the door
- Pump housing seal worn — often a slow drip under the machine
- Water inlet valve dripping when closed
For the LC error, tilt the front of the machine up slightly (use a folded towel) to let water drain from the flood sensor tray. Once dry, reset and test. If the leak source isn’t found and fixed, the code will return immediately.
Samsung dishwasher making noise
- Grinding: Foreign object in the pump — glass, a bone, a pit. Drain the machine and inspect the filter and pump area.
- Buzzing / rattling: Spray arm hitting a dish or the filter assembly not seated correctly.
- Loud humming: Wash pump motor bearing wearing out. More common on machines over 5 to 7 years old.
- Clicking: Normal — water fill valve cycling.
When to call a technician
Clean the filter, check the drain hose, and reset error codes yourself. Call for help with motor faults (3C/3E), control board issues, pump replacement, or recurring leak codes after basic inspection.
