What Does Error F18 Mean?
The Whirlpool Washer Dryer F18 error code signifies a drain pump failure, often linked to excessive foam or suds during the wash cycle. This can result in the machine being unable to drain water effectively, accompanied by unusual sounds. Commonly, this issue arises from using too much detergent, leading to foamy buildup, or it may indicate a restricted drain hose. In rare cases, an internal control error may be the culprit.
Common Symptoms:
- Error displayed during or before wash cycle
- Cycle may stop or not complete
- Washer unable to drain properly with foam present
- Excessive suds in drum
Possible Causes
- Excessive foam/suds due to detergent issues (high)
- Restricted or blocked drain hose/pump interference from suds (medium)
- Internal control/board error in washer‑dryer combo (less common) (low)
