Quick answer
Whirlpool lists excessive foam as the reason for Fod or F18 on compact front load washers.
Model note: Whirlpool reuses codes across series and model years, so Fod / F18 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
Fod or F18 means too much foam stopped the program.
Why it shows
Too much foam on a compact front load Whirlpool washer interrupts the program and shows Fod or F18. The washer may stop again and again until the suds die down.
Clearing it
Run Rinse & Spin with the Intensive Rinse option.
Confirm the drain pump filter is clean.
Next time, dose to the detergent maker’s recommendation; the Dosing Aid option is worth considering.
Causes to rule out
Always choose HE (high-efficiency) detergent. Regular detergent or an oversized dose produces excessive suds, and that can mean leaks, draining concerns and weak rinsing. Also inspect the drain hose for kinks or clogs, since a restricted hose or standpipe can trigger Fod.
