Maytag Dishwasher Error Code 88

The 88 code on a Maytag dishwasher indicates that the appliance has entered Field Service Test mode. This is a diagnostic routine used by technicians to test individual components such as the wash motor, drain pump, and heating element. It is not a fault code and does not indicate a broken part. The display of 88 simply confirms the test sequence has started.

The dishwasher is not in a normal operating mode when 88 is displayed, so you should exit the test mode before running a regular wash cycle. The code itself does not indicate any safety hazard. Once you exit the service mode, the appliance should function normally.

In most cases, no repair cost is involved when 88 appears. The code indicates test mode entry, not a component failure. If the mode was triggered accidentally, simply resetting the unit resolves the situation at no cost. If a stuck or faulty control panel button is causing repeated unintended activation, replacement of the control panel or button assembly may be needed, with parts and labor typically ranging from 80 to 250 dollars depending on the model.

To exit Field Service Test mode, you can typically cycle the power to the dishwasher by pressing the cancel or power button, or by turning off the circuit breaker for 30 to 60 seconds. Restoring power should return the dishwasher to its normal standby state. If the mode reactivates on its own, inspect the control panel for stuck buttons.

Yes, a power reset will generally clear the 88 display and exit the Field Service Test mode. Turn off power to the unit at the circuit breaker or unplug it, wait at least 30 seconds, and then restore power. The dishwasher should return to its normal operating state.
