Error codeE18
ApplianceWashing Machine
Quick answer
E18 indicates the washer is not draining within the expected time.
Model compatibility: DCS reuses codes across series and model years, so E18 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The E18 code means the washing machine detected a drainage problem — water is not leaving the drum as it should. It commonly relates to the pump filter or drain path.
Signs
Symptoms you may notice
Water remaining in the drum
E18 appears during the drain phase
Door stays locked until water clears
Why it happens
Possible causes
A clogged pump filter (often catches coins and lint)
A blocked or kinked drain hose
A drain pump fault
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Check and clean the pump filter following your manual’s procedure
Confirm the drain hose is not kinked or pinched
Ensure the standpipe or drain is not blocked
Important safety warning. Clear the pump filter carefully — water will spill out. Avoid deeper disassembly, which involves electrical components best left to a technician.
Please avoid
What not to attempt
Do not remove the drain pump yourself
Do not force the door while water remains
Do not run further cycles until drainage is restored

When to call a technician
If cleaning the filter and checking the hose does not resolve E18, book a diagnosis to test the drain pump.
