Whirlpool Dishwasher F8E4 Error: Causes & Fixes

On Whirlpool dishwashers, error code F8E4 means the leak-detection float switch in the base pan/drip tray has detected water; the dishwasher runs an automatic drain sequence and locks out normal operation until the condition clears. The identical content is published on Maytag's product help site.

Before you work on your dishwasher

  • Power: Unplug the dishwasher or switch off its circuit breaker before removing panels or touching wiring.
  • Water: Turn off the water supply valve before disconnecting hoses or the inlet valve.
  • Heat: Water and the heating element can be hot right after a cycle; let the dishwasher cool first.
  • Sharp debris: Wear gloves when reaching into the filter or sump; broken glass often collects there.
  • Stop: If you smell burning, see smoke or sparks, or find water near wiring, switch off the breaker and call a technician.
  • Disconnect power before accessing internal dishwasher parts: Unplug the dishwasher or switch off the circuit breaker that powers it before removing panels, the filter, or the drain pump cover, or before reaching into the sump.
  • Shut off the water supply before disconnecting hoses: Turn off the water supply before disconnecting the drain hose, siphon connection, or water inlet, or before pulling the dishwasher out for service.
  • Hot water and steam scald risk: Open the dishwasher door carefully during or right after a cycle. Hot water or steam can escape and cause burns; wait until water noises stop and steam subsides before fully opening the door.

What causes Whirlpool F8E4

  1. Water already accumulated in the base drip tray: Water already sitting in the base drip tray/pan, left over from a prior leak, spill, or condensation, keeps the float switch tripped and F8E4 active until the tray is emptied. Difficulty 2/5.
  2. Water-supply connection leaking (new installation): On a newly installed dishwasher, an improperly seated water-supply connection (loose fitting or a rubber washer that isn't seated) can leak into the base pan and trigger F8E4. Difficulty 1/5.
  3. Float switch connector not fully seated: A float switch connector that is not fully seated in its housing can register as a leak condition and trigger F8E4. Difficulty 2/5.
  4. Excessive detergent or dish-soap suds: Using dish soap or too much dishwasher detergent creates excessive suds; the suds can push water out of the tub where it pools in the base pan and registers as a leak. Difficulty 1/5.
