Quick answer

E18 indicates the washer is not draining within the expected time.

Model compatibility: Thermador 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
Get help

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.
