Maytag Dishwasher Error Code Motor low current

This error means the control board detected insufficient current draw from the wash motor during the Field Service Test. The Delay LED and Light Wash LED will flash together to indicate this fault. It points to a problem with the motor itself, its wiring connections, or the harness leading to it. The motor is responsible for circulating water during the wash cycle, so the dishwasher will not perform correctly until this is resolved.

Running the dishwasher with this error active is not advisable. Because the fault is with the wash motor or its circuit, the dishwasher may not circulate water properly, leaving dishes unwashed. In some cases the unit may stop mid-cycle. Continuing to run it does not typically cause further damage, but it will not clean effectively and the underlying issue will not resolve itself.

Disconnect power to the dishwasher before beginning. Locate the wash motor and identify terminals ST5 and ST8 on the motor connector. Set a multimeter to the ohms setting and place the probes on these two terminals. A reading of 3 to 4 ohms indicates the motor windings are intact. A reading significantly below or above this range confirms the motor has failed and needs to be replaced. If resistance tests good, shift focus to the wiring harness and connectors leading to the motor.

Start by checking the wiring connections at the motor, particularly at terminals ST5 and ST8. Look for corrosion, loose connectors, or damaged wires. Next, use a multimeter to measure resistance between ST5 and ST8 on the motor itself. A healthy motor should read 3 to 4 ohms. If the resistance is outside this range, the motor needs to be replaced. If wiring and motor resistance both check out, the control board may need to be evaluated by a technician.

If the fix is simply reseating a loose connector or cleaning a corroded terminal, there is no parts cost. If the wash motor needs replacement, expect to pay between $80 and $200 for the part depending on the model, plus labor if you hire a technician. A service call from an appliance repair technician typically runs $75 to $150, with total repair costs for a motor replacement commonly falling between $150 and $350. Testing the motor resistance yourself with a multimeter before calling a technician can help you avoid paying a diagnostic fee for a simple wiring fix.
