Maytag Dishwasher Error Code 3-2

The 3-2 code means the dishwasher has detected a shorted connection or component in the Temperature Sensing Circuit. This can be caused by a failed temperature sensor, damaged wiring, a faulty input on the control board, or incoming water that is hotter than 75 degrees Celsius (167 degrees Fahrenheit). The dishwasher stops normal operation when this fault is present to protect the system.

It is not recommended to continue running the dishwasher while this fault is active. The Temperature Sensing Circuit is critical for controlling water heating during the wash and dry cycles. Running the machine without reliable temperature monitoring could result in improper washing or overheating conditions.

Resetting the dishwasher by unplugging it or cutting power may temporarily clear the displayed code, but the fault will return if the underlying problem has not been corrected. A reset is useful as part of diagnosing the issue, but it is not a fix for a shorted sensor, damaged wiring, or a faulty control board input.

Some causes are approachable for a confident DIYer. You can check the incoming water temperature and inspect visible wiring and connectors without any special tools. Testing the temperature sensor and circuit wiring requires a multimeter. Replacing the sensor is a straightforward repair, but if the control board is the cause, that replacement is more involved and may warrant professional service.

Repair costs depend on the root cause. A replacement temperature sensor is generally an inexpensive part, with DIY repair costs typically ranging from $15 to $40 for the part alone. If the control board is the cause, parts and labor costs can range from $150 to $350 or more depending on the model and service rates in your area.
