Maytag Dishwasher Error Code SF5

SF5 indicates that the control board has detected a problem with the current sensor, either reading an out-of-range value or receiving an intermittent signal. The current sensor monitors the power draw of the wash motor during operation. The dishwasher stops running when this code appears to protect the motor from potential damage. The fault is typically traced to a wiring or connector issue, a bad sensor, or a failed control board.

It is not recommended to continue running the dishwasher while the SF5 code is active. The code indicates the control board cannot reliably monitor motor current, which means a motor overload or electrical fault could go undetected. Continuing to operate the appliance in this state risks damage to the motor or other electrical components.

Repair costs vary depending on which component is at fault. If the issue is just a loose connector, there may be no parts cost at all. Replacing a current sensor typically runs in the range of $20 to $60 for the part. A replacement control board is the most expensive scenario, often ranging from $100 to $250 or more for the part alone, with additional labor costs if a technician is hired.

Some causes of SF5 are accessible to a knowledgeable DIYer. Checking and reseating the wiring connectors at the current sensor and along the harness between the motor and control board requires basic tools and no specialized equipment. If those steps do not resolve the code, testing or replacing the current sensor or control board is more involved and may be better handled by a technician.

A reset may temporarily clear the SF5 code, but if the underlying cause is not repaired, the code will return once the dishwasher runs again and the control board re-detects the sensor fault. Resetting is useful for confirming whether the issue is intermittent, but it is not a fix. The wiring, connectors, current sensor, and control board all need to be inspected and tested.
