What the F3-E1 error code actually means

Your Maytag dishwasher is displaying this error because it cannot read the water temperature during a wash cycle. The temperature sensor, which tells the dishwasher how hot the water is, either has a broken connection or has stopped working entirely. The dishwasher pauses operation until this is resolved to avoid running a cycle without knowing the water temperature.

Questions people ask about F3-E1

What does F3-E1 mean on a Maytag dishwasher?
F3-E1 indicates an open connection or faulty component in the temperature sensing circuit. The dishwasher's control board is not receiving a valid signal from the temperature sensor, which monitors water temperature during the wash cycle. The appliance stops normal operation until the circuit issue is identified and repaired.
Is it safe to keep using my dishwasher while F3-E1 is displayed?
It is not recommended to continue running the dishwasher with F3-E1 active. Without accurate temperature data, the control board cannot properly manage the wash and dry cycles, which may result in poor cleaning performance or improper sanitization. The dishwasher will typically halt operation on its own when this code is present.
How much does it cost to repair a Maytag dishwasher F3-E1 error?
Repair costs vary depending on the root cause. A replacement temperature sensor typically costs between $15 and $50 for the part alone. If the control board requires replacement, parts alone can range from $100 to $250 or more. Adding professional labor will increase the total, generally ranging from $100 to $200 for a service call and repair.
Can I fix the F3-E1 error code myself?
Some causes of F3-E1 are DIY-friendly, such as reseating a loose wiring connector or cleaning corroded terminals. However, replacing the temperature sensor or control board requires basic electrical knowledge and comfort working with appliance wiring. Always unplug the dishwasher before inspecting or handling any components.
Will resetting the dishwasher clear the F3-E1 error?
A reset may temporarily clear the code, but F3-E1 will return if the underlying fault in the temperature sensing circuit has not been repaired. To clear the code permanently, the failed sensor, damaged wiring, or faulty connector must be addressed. Use the Service Diagnostics Cycle after any repair to confirm the circuit is functioning correctly.
