What Does Error F18 Mean?
The Whirlpool Washing Machine error code F18 (or FOD) indicates a foam or suds issue detected during the wash or drain process. This error occurs when excessive suds interrupt normal operation, preventing the washer from draining or spinning effectively. Common symptoms include the display of the F18 code, a stalled cycle, and visible foam in the drum. The primary cause is typically the use of non-HE detergent or an excessive amount of detergent, leading to foam buildup.
Common Symptoms:
- Washer displays F18 or FOD during or after wash cycle
- Cycle stalls or repeatedly attempts to drain/continue
- Excess foam visible in drum or during draining
Possible Causes
- Excessive suds/foam due to non‑HE detergent or too much detergent (high)
- Restricted draining aggravating foam issue (kinked/clogged drain hose) (medium)
