Whirlpool Dishwasher F8E4 Error Code: What It Means & How to Fix It

F8E4 = Water detected in the drip tray. F8E4 means the float switch found water in the drip tray under the dishwasher. In other words, something is leaking. Whirlpool says to check the water connections, suds and the float switch, then empty the tray.

Can you fix it yourself? Maybe

Check your model: Error codes can mean different things on different Whirlpool models. Find your model number (usually on a sticker inside the door or lid, or on the back) and confirm the code in your user manual.

Safety first: Unplug the appliance (or switch off its breaker) before you remove panels, filters or hoses. Turn off the water supply valves before you disconnect any hose, and keep a towel and shallow pan handy. Never work on wiring, gas lines or sealed refrigerator systems yourself.

How to fix Whirlpool Dishwasher F8E4

Turn off the water supply to the dishwasher.
Press Cancel once to silence the alarm, and keep the door closed.
On new installs, check the fill connection: the rubber washer must be seated and the 3/4" fitting hand-tightened plus 1/4–1/2 turn.
Make sure the float switch connector is plugged in and locked.
Empty the drip tray carefully, without yanking the float switch wire.
Press Cancel twice to clear the code.

Still showing F8E4?

If you can't find the leak, or the professionally installed unit keeps throwing F8E4, schedule service.

Repair or replace?

If the appliance is under warranty, call Whirlpool first, since a repair may be free. Out of warranty, a common rule of thumb is to compare the repair quote with the cost of a new unit and the appliance's age before deciding.
