Water found in the drip tray on KitchenAid dishwashers.

KitchenAid All KitchenAid dishwasher codes

F8E4

Moderate DIY

The float switch in the base pan has lifted because water collected under the tub, and the machine starts a drain and won't run until it's cleared. Most often it's a loose supply fitting, a washer that isn't seated, or suds overflowing from the wrong detergent.

Compatible models

Used across KitchenAid built-ins that have a drip tray float switch; KitchenAid doesn't name the models.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix KitchenAid F8E4

Stop the water and let it drain
Shut the water supply valve under the sink. Press Cancel once to silence the alarm and keep the door closed with power on so the unit can pump out. If water is near the outlet or cord, switch off the breaker instead of touching the plug.
Check the supply connection
Once the tub has pumped out, cut the power. Look at every fitting on the fill line. The rubber washer has to sit flat in the 3/4 in (19 mm) elbow; hand-tighten it, then snug the coupling with pliers. A further 1/4 to 1/2 turn often seals a seeping gasket.
Empty the drip tray and reseat the float switch
With power still off, release the snaps on each side of the drip tray and ease it toward you gently, since the float switch wire is still attached. Dry it out, then make sure the float switch connector is pushed in until its locking tab shows.
Clear the code
Restore water and power, press Cancel twice to clear the code, and watch the first fill for drips. Check for suds too, and switch to automatic-dishwasher detergent if you've been using anything else.

When to call a technician

If water keeps showing up in the base after the fittings are tight, there's a leak inside the machine that a technician needs to find.
