Whirlpool Dishwasher F8E4 Error Code
Water in the drip tray. Here is what it means and how to clear it, easiest fix first.
The float switch in the drip tray under the tub has detected water, which points to a leak. Whirlpool's checks cover loose water supply fittings and a disconnected float switch (common right after installation) and too many suds pushing water out of the tub.
On models without a digital display, the Clean light shows this as 8 quick flashes, a short pause, then 4 flashes, repeating after a longer pause. When this code appears, the dishwasher may start a drain sequence and block normal use.
How to fix Whirlpool F8E4
Stop the leak source
Turn off the dishwasher's water supply and press Cancel once to silence the alarm. Keep the door closed and leave the power on so the drain sequence can pump out the tub. If water has reached the floor near the outlet or cord, do not touch the plug or panel; switch off the dishwasher's breaker instead.
Check for suds
If you see foam in the tub, let it settle. Use only automatic dishwasher detergent in the recommended amount; dish soap will overflow the tub.
Check fittings and empty the tray
With the breaker off, remove the toe kick panel. Check that the supply fitting at the inlet valve has its rubber washer in place, was started by hand so it is not cross-threaded, and is snug (a further quarter to half turn with pliers may be needed to seal). Press in the side tabs to slide out the drip tray gently, since the float switch wire is still attached, then empty and dry it and make sure the float switch connector is fully latched.
Clear the code
Restore water and power, press Cancel twice to clear the code, and run a short cycle while you watch for drips.
When to call a technician
If you can't find the source of the water, or the code returns with the tray dry and fittings tight, schedule service.

Frequently asked questions
What does F8E4 mean on a Whirlpool dishwasher?
The float switch in the drip tray under the tub has detected water, which points to a leak. Whirlpool's checks cover loose water supply fittings and a disconnected float switch (common right after installation) and too many suds pushing water out of the tub.
Can I fix Whirlpool F8E4 myself?
Often. The first steps above are safe checks a homeowner can do. If they don't clear F8E4, the cause is likely a worn part that needs replacing.
What if F8E4 keeps coming back?
A code that returns after a reset and the checks above usually means a part is wearing out. Note when F8E4 appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
