Whirlpool Washer Error Code FP

FP on a Whirlpool washer stands for a drain fault, indicating the machine has encountered a problem with the drain pump or pressure switch that is preventing proper draining. The washer monitors how long draining takes and triggers this code when it cannot confirm the tub has emptied within the expected window. Both the pump and the pressure switch are involved in this process, so either component could be the root cause.

Resetting the washer by unplugging it for a few minutes may temporarily clear the FP code, but it will return if the underlying drain issue is not corrected. The fault is triggered by an actual condition the washer detects, not a random glitch, so a reset alone is not a fix. Address the drain pump and pressure switch before relying on a reset.

If the fix is simply cleaning a clogged pump filter or straightening a drain hose, there may be no parts cost at all. Replacing a drain pump motor typically costs between $25 and $100 for the part, plus labor if a technician is involved. A replacement pressure switch generally runs between $15 and $50. Total repair costs including professional labor can range from $100 to $250 depending on which component has failed.

Start by cleaning the drain pump filter, which is usually behind a small access panel at the front lower section of the machine. Next, check the drain hose for kinks or blockages and confirm it is not inserted too deeply into the standpipe. If the filter and hose are clear but the code persists, the drain pump motor or pressure switch may need to be tested and replaced.

You should not continue running the washer while the FP code is active. If water cannot drain properly, the machine may overflow or leave standing water in the drum for extended periods, which can damage internal components and promote mold growth. Stop the cycle, drain any standing water manually if needed, and resolve the fault before running another load.
