Whirlpool Washer Error Code Unexpected Fill During Agitation/Soak

This error means the washer's pressure switch detected a drop in water level during the agitation or soak phase, when the tub should remain full. The control board responds by stopping the agitation, running a drain cycle, and halting the wash. Common causes include a siphoning drain hose, a damaged pressure switch hose, a tub leak, or water being removed from the drum after the fill completed.

It is generally safe to attempt a reset and one additional cycle, but you should monitor the machine closely for visible water on the floor or signs of continuous draining. If the error repeats or you notice leaking, stop using the washer until the cause is identified and corrected. Running the machine with a tub leak or a siphoning drain hose can lead to water damage over time.

Verify that the drain hose exits the back of the washer and loops up to a height of at least 34 to 36 inches before entering the standpipe or utility sink. If the hose drops straight down without this high loop, a siphon can form that continuously removes water during the cycle. Securing the hose at the correct height with a hose guide or clip is a straightforward fix that requires no parts replacement.

Yes, pressing the START/OFF button resets the operation mode and the washer will execute a fresh Fill task before resuming the previously selected cycle. However, if the underlying cause such as a drain hose siphon or a leaking tub is not addressed, the error is likely to return during the same or a future cycle.

The repair cost depends on the cause. Correcting a drain hose installation is typically free or very low cost. Replacing a pressure switch hose or the pressure switch itself is generally in the range of $15 to $60 for parts if done as a DIY repair, or $100 to $250 if a technician is involved. Tub seal or door seal repairs tend to cost more, often in the $150 to $400 range depending on labor and parts.
