Maytag Dishwasher Error Code 1F5

The 1F5 code means the control board has detected that the current sensor is not responding to any electrical load changes in the machine. Normally, the sensor detects shifts in current as components like the motor or pump turn on and off. When the board sees a flat, unchanging signal, it flags 1F5 to indicate the current sensor circuit is not operating correctly. This can result from a wiring connection problem or a faulty control board.

A reset may temporarily clear the 1F5 code, but it will return if the underlying cause has not been corrected. Because the error is triggered by a consistent lack of sensor response, the board will detect the same fault condition again as soon as a new cycle runs. Addressing the wiring connection or board issue is necessary for a lasting repair.

If the fix is simply reseating or reconnecting the black power line at the spade terminal, there may be no parts cost involved, though a service call fee typically ranges from $75 to $150. If the control board needs to be replaced, parts and labor combined can range from $200 to $400 or more depending on the model and local labor rates. Getting a diagnosis first helps determine which scenario applies before committing to a repair.

Start by checking that the black power line is properly connected to the 1/2 inch spade terminal on the control board, as this is the most common cause. Also inspect all harness connectors at the board for corrosion, bent pins, or loose seating. If connections are all confirmed secure and correct but the code returns, the control board may need to be replaced.

It is best not to run the dishwasher while this code is active. The current sensor is part of the board's ability to monitor electrical loads, and operating without proper sensing could prevent the machine from detecting fault conditions that protect components. Resolving the wiring or board issue before resuming use is the recommended course of action.
