Maytag Dishwasher Error Code F3-E2

F3-E2 indicates a shorted connection or component in the temperature sensing circuit. It can be triggered by incoming water that exceeds 167°F (75°C) or by a faulty thermistor, damaged wiring, or a bad connector. The dishwasher stops operating to prevent uncontrolled heating until the fault is resolved.

It is not recommended to continue running the dishwasher with an active F3-E2 fault. The temperature sensing circuit monitors water heat during the cycle, and a shorted or faulty sensor means the control cannot accurately regulate temperature. Running the appliance in this condition could result in overheating or ineffective wash performance.

Repair costs vary depending on the cause. Adjusting the water heater temperature costs nothing. A replacement thermistor typically ranges from around $15 to $50 in parts, and DIY installation is feasible for many technicians. If professional labor is needed for wiring repairs or a control board replacement, total costs can range from $100 to $350 or more depending on the specific component and service rates in your area.

Some causes are DIY-friendly. Start by checking your water heater temperature setting, since water above 167°F (75°C) will trigger this code on its own. If water temperature is normal, you can unplug the dishwasher and use a multimeter to test the thermistor and inspect wiring and connectors for shorts or corrosion. Replacing a thermistor is a moderate DIY repair, but if the control board is at fault, many homeowners prefer professional service.

A reset may temporarily clear the code, but it will return if the underlying fault is still present. If the cause is incoming water that is too hot, correcting the water heater setting and then resetting the unit may resolve it permanently. For a failed thermistor, damaged wiring, or shorted connector, the hardware issue must be repaired before the code will stay cleared.
