Whirlpool Dishwasher Error Code F8 E3 — Dispenser Motor Failure
What this means
The F8 E3 error code on Whirlpool dishwashers indicates the detergent dispenser motor/actuator has failed. The dispenser should open during the wash cycle to release detergent. If the motor cannot open the dispenser door, detergent stays trapped and dishes are not cleaned properly. Causes include a failed dispenser motor, a stuck dispenser latch, or a wiring issue.
Alternate codes: F8E3
Step-by-step fix
3 stepsManually check the dispenser
Open the dishwasher door. Check the detergent dispenser cup. Try opening and closing it by hand. If it is stuck, look for dried detergent, old rinse-aid residue, or foreign objects jamming the mechanism.
Soak the dispenser with hot water and vinegar to dissolve caked-on detergent or rinse aid.
Clean the dispenser mechanism
Use a damp cloth and hot water to thoroughly clean the dispenser cup, the latch mechanism, and the pivot points. Ensure the spring-loaded latch moves freely.
Using too much detergent or the wrong type can cause buildup that jams the dispenser over time.
Test and replace the dispenser actuator
Remove the inner door panel to access the back of the dispenser. Locate the wax motor or solenoid actuator that triggers the dispenser door. Test it with a multimeter for continuity. If it is open, replace the dispenser assembly.
Dispenser assemblies are usually replaced as a complete unit — the motor and latch are integrated.
When to call a professional
If the dispenser assembly is new but the error persists, the control board's dispenser output circuit may be damaged.
