What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
Fod or F18 means excessive suds interrupted the cycle.
Fod, or F18, appears when excessive foam, or suds, interrupts the program on a Whirlpool compact front load washer. The interruption can repeat several times until the foam is reduced enough.
What to do now
Start the Rinse & Spin program with the Intensive Rinse option. Make sure the drain pump filter is clean. For future loads, follow the detergent manufacturer’s dosing recommendations and consider the Dosing Aid option.
Also check
Detergent type. Use only HE high-efficiency detergent. Non-HE detergent, or more than the recommended amount, can cause excessive suds, which can lead to leaking, draining concerns and poor rinsing.
Drain hose. Make sure it is not kinked or clogged. A restricted drain hose or standpipe (drainpipe) can bring on Fod.

If Fod returns after a clean filter, a clear hose and the right detergent, call (310) 448-6692 or see washer repair. Share the model number and the detergent steps you took.
Stop immediately if you notice smoke, sparks, a burning smell, gas odor, or water near electrical parts.
Safe
Important
Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
