Whirlpool Dishwasher Error F8E4 – Water in Drip Tray – Leak Detected
A float switch under the tub found water in the drip tray. Find the leak before clearing the code.
Safety first · Consult a professional
Turn off the breaker and close the water valve before removing the toe kick. Water in the drip tray sits right next to wiring and the inlet valve terminals, so never reach in with the power on.
- Unplug the appliance or switch off the breaker before opening any panel. Mains voltage can kill.
- Water and electricity: unplug first, keep towels ready and never stand in water while the appliance is connected.

Whirlpool files F8E4 under leaks: the float switch in the drip tray below the tub has lifted, so the control assumes water is escaping inside the cabinet. The dishwasher stops the cycle and beeps until you cancel it. Whirlpool's own checklist points first at the water supply connection, where a rubber washer that isn't seated lets water spray into the base, then at the float switch wiring, the tray itself and oversudsing. The code will not stay cleared while the tray still holds water, so emptying it is part of the fix, not the fix itself.
How it looks on the display
Model families & display variants
| Model family | Shows | Note |
|---|---|---|
| Models with a digital display | F8E4 | May also be written F8 E4 or F8-E4; all mean the same leak detection. |
| Models without a numeric display | 8-4 | A status light flashes 8 times, pauses, then flashes 4 times, and the pattern repeats. |
| KitchenAid and Maytag dishwashers on the same platform | F8E4 | These share Whirlpool's code table, so the same drip tray check applies. |
Symptoms
- F8E4 on the display, or a status light flashing 8 times, pausing, then 4 times
- Beeping that stops only after pressing Cancel
- Cycle stopped; on many models the drain pump runs
- Water visible in the drip tray behind the toe kick
- Damp floor or cabinet base under the dishwasher, or suds at the door
Possible causes
Ranked by how often each cause is behind this code (editorial estimate).
- Leak at the water supply connection, washer not seated or fitting loose
- Oversudsing from hand dish soap or wrong detergent
- Drain hose connection or clamp leaking at the pump
- Water escaping at the door or vent from a misloaded or unlevel unit
- Pump or sump seal leaking into the base
- Float switch stuck or its wiring faulty
Fix it step by step
Silence and secure
Press Cancel once to stop the alarm and once more to clear the code. Then close the water valve under the sink and turn off the breaker.
Remove the toe kick and look
Unscrew the lower access panel and shine a light into the base. Note where the water sits and whether it's clear, soapy or dirty: clear points to the supply side, soapy to suds or the door, dirty to the pump or drain hose.
Tools: Screwdriver, Flashlight
Empty the drip tray
On models with a removable tray, press the snap on each side toward the center and slide the tray out carefully. Otherwise soak the water up with towels until the float drops.
Tools: Towels & shallow pan, Gloves
Reseat the supply fitting
Check that the rubber washer sits flat inside the coupling at the inlet elbow. Hand-tighten the coupling until snug, then add a quarter to half turn with pliers, as Whirlpool recommends.
Tools: Pliers, Flashlight
Check wiring clearance and the float
Make sure the float moves freely and its wire connection is secure, and that no power cord or harness rests against the motor or the lower tub.
Tools: Flashlight
Run a watched test
Leave the toe kick off, restore water and power, and run a short cycle with a flashlight on the base. Watch the supply fitting, the drain hose clamp and the pump area for the first drips.
Tools: Flashlight, Towels & shallow pan
How to reset F8E4
- Press Cancel once to silence the alarm, then press it again to clear the code.
- Make sure the drip tray is empty and dry; the code returns as long as the float is lifted.
- Restore power and start a short cycle while watching for leaks.

Rough US estimates; technician call-out fees vary by region. Not a quote.
When to call a technician
Call a technician if water keeps collecting in the tray with the supply fitting dry and no suds, since that usually means a pump or sump seal inside the machine. Also call if the floor or cabinet is getting wet, before the subfloor soaks it up.
Frequently asked questions
Can I just dry the tray and keep using the dishwasher?
Only once you know where the water came from. If it was a one-time sudsing accident, drying is enough. If it was the supply fitting or a seal, it will keep leaking into the cabinet.
What does 8-4 mean on a Whirlpool without a display?
It's the flashing-light version of F8E4: eight flashes, a pause, then four. It means the same thing, water in the drip tray.
Why did F8E4 appear right after installation?
The supply connection is the usual suspect. If the rubber washer in the coupling isn't seated or the fitting is only hand-tight, water can spray into the base as soon as the valve opens.
How long does it take for the float to reset?
As soon as the water is gone and the float drops. Soaking up the water with towels is quicker than waiting for it to evaporate, which can take a day or more.
