Went on a service call in Parker, Arizona for a Whirlpool washer, model number WTW8500DC0, that wasn’t filling fast enough, very slow fill and it would time out per the control board. The error code was F8E1 LONG FILL.
I checked the customers water pressure to the washer on both hot and cold and it was good water pressure. Then I checked the water inlet valve screens and they were not clogged.
I ordered a new water inlet valve and went back to the customers house to install it, and it worked great, much faster water fill and no more error code F8E1.

Here’s the water inlet valve for this model:
W11165546 Valve
W11165546 water inlet valve
