|---|---|---|
| Loose or misaligned water supply fitting | Drips under the dishwasher, often after installation | The rubber washer and the 3/4-inch elbow fitting |

Stop the water and the alarm
Turn off the water supply to the dishwasher and press Cancel once. If a professional installed the dishwasher, leave the power on and the door closed: the drain sequence runs on its own and blocks operation until it's done. Then contact service.
-
Check the water supply connection
If you installed it yourself, make sure the rubber washer sits in the fitting. Slide the 3/4-inch (19 mm) fitting of the 90-degree elbow onto the valve and hand-tighten it, then snug it with pliers. It may need another 1/4 to 1/2 turn to seal. The fill hose should exit at the rear left of the unit.
Safety: Turn off the water and power before you work under the dishwasher. Hand-tighten first to avoid cross-threading.
-
Check the float switch and power cord
Make sure the float switch is connected: line up the connector with its housing and push until the locking tab shows over the back. Keep the power cord away from the motor and the lower tub.
Safety: Switch off the dishwasher's power at the outlet or breaker before you reach into the base.
-
Empty the drip tray
If the drip tray holds water, press the snap on each side toward the center and pull the tray toward you. Empty it and slide it back.
Safety: Pull gently. The float switch wire stays attached and can be damaged.
-
Clear the code and test
Press Cancel once to silence the alarm and again to clear the code. Turn the water back on, run a short cycle and watch for drips. Clean the dishwasher every 30 days or so with affresh Dishwasher Cleaner to keep residue down.
When to call a technician
If F8 E4 returns with a tight supply fitting, a connected float switch, no suds and an empty tray, water is leaking inside the dishwasher. Keep the water off and contact Whirlpool service.
Questions people ask
Is F8 E4 a drain pump error?
No. Whirlpool's code list defines F8 E4 as water detected in the drip tray. The dishwasher drains because it found water in the base, not because the pump failed.
How do I clear F8 E4 on a Whirlpool dishwasher?
Find and fix the water source, empty the drip tray, then press Cancel once to silence the alarm and a second time to clear the code.
What do 8 flashes and 4 flashes mean?
On Whirlpool dishwashers without a display, the Clean light flashes the F number, pauses 1 to 2 seconds, then flashes the E number. 8 flashes, a pause and 4 flashes is F8 E4.
