Whirlpool Dishwasher FAE4 Error Code

Dispenser actuator position not confirmed

What this error means

FAE4 means the detergent dispenser actuator did not reach the expected position after the control sent open command—related to F8E4 but specifically on models that monitor actuator travel with a position switch.

Common causes

  • Wax motor plunger stuck from hardened detergent buildup
  • Broken dispenser door spring not allowing full open travel
  • Position switch on the dispenser not actuated when door opens
  • Door harness wire broken at the hinge from repeated door flexing

Step-by-step fixes

  1. 1Soak the dispenser cup with hot water and clear hardened detergent from the wax motor area
  2. 2Manually flip the dispenser lid—it should spring back and latch smoothly
  3. 3Run a cycle and watch the dispenser during first wash fill for full door swing
  4. 4Use liquid or powder detergent until FAE4 clears to rule out pod sticking

When to call a technician

Dispenser door moves freely by hand but FAE4 every cycle needs dispenser assembly with wax motor replacement.
