Whirlpool Dishwasher Error Code F3 E3 — Heating System Failure
What this means
The F3 E3 error code on Whirlpool dishwashers indicates the heating system has failed to raise the water temperature to the required level within 25 minutes of the cycle starting. This is usually caused by a burned-out heating element, a faulty thermostat, or very cold incoming water. Hard water areas are especially prone to this issue, as mineral deposits can coat the heating element and reduce its efficiency.
Alternate codes: F3E3
Step-by-step fix
4 stepsVerify the incoming water temperature
Run the hot water faucet at the kitchen sink until it is fully hot before starting the dishwasher. The incoming water should be at least 120°F (49°C). If it takes a very long time to get hot water, the dishwasher may time out before it can heat the water.
Running hot water at the sink before starting the dishwasher is a good habit that helps every cycle clean more effectively.
Inspect the heating element
Turn off the circuit breaker for the dishwasher. Open the door and look at the heating element ring at the bottom of the tub. Check for visible breaks, blistering, or heavy mineral deposits.
White crusty buildup on the element is mineral scale from hard water — you can try removing it with white vinegar before replacing the element.
Test the heating element with a multimeter
Access the heating element wiring from underneath the dishwasher by removing the lower front access panel. Disconnect the wires and test resistance across the element terminals. A functional element should read 15-30 ohms.
Also test each terminal to the dishwasher frame (ground). Any reading other than infinite indicates a grounded element that must be replaced.
Replace the heating element
If the element is faulty, remove the retaining nuts underneath the tub that secure the element terminals. Carefully lift the old element out through the inside of the tub. Install the new element and tighten the retaining nuts.
When installing the new element, use the mounting brackets to ensure it sits above the tub bottom and does not touch plastic components.
When to call a professional
If the heating element tests fine, the issue may be with the control board or thermostat, which requires professional diagnostic equipment to test properly.
