What Motor low current means on a Maytag dishwasher

The Motor Low Current error on a Maytag dishwasher is detected during the Field Service Test, when the control board monitors current draw from the wash motor and finds it is pulling less current than expected. Low current draw typically points to a motor winding failure, a broken or corroded connection in the motor circuit, or a motor that is not receiving proper voltage. The Delay LED and Light Wash LED flashing simultaneously is the visual indicator for this specific fault. Technicians should begin diagnosis by measuring resistance across the motor terminals ST5 and ST8, which should read 3 to 4 ohms on a properly functioning motor.

For homeowners, this error means the dishwasher's main wash motor is not working correctly. The motor is responsible for circulating water through the spray arms during a wash cycle, so a fault here usually means the dishwasher will not clean dishes properly or may stop mid-cycle. The control board noticed the motor is drawing less electrical current than it should, which signals a problem with the motor itself or the wiring connecting it. This is not a software glitch or a sensor issue. The motor or its wiring connections need to be physically inspected and tested before the dishwasher will operate reliably again.

Common causes of Motor low current

  1. 01

    Loose or corroded motor wiring connections

    Wiring / connection

    A poor connection at the motor terminals, particularly at ST5 or ST8, can reduce current flow enough to trigger this fault. Corrosion, a partially unseated connector, or a damaged wire terminal are common culprits and should be inspected first.

  2. 02

    Failed wash motor windings

    Part replacement

    If the motor windings have broken down internally, resistance will fall outside the 3 to 4 ohm range measured between ST5 and ST8. A motor reading significantly below or above this range needs to be replaced.

  3. 03

    Damaged motor wiring harness

    Part replacement

    A chafed, pinched, or broken wire in the harness running to the motor can interrupt current flow. Visual inspection along the full length of the harness may reveal the damaged section.

  4. 04

    Faulty control board

    Part replacement

    If the motor and all wiring connections test within spec, the control board's motor drive circuit may be failing to supply proper voltage, causing a false low-current reading. This is the least likely cause but should be considered after all other components are confirmed good.

Frequently asked questions about Motor low current

What does the Motor Low Current error mean on a Maytag dishwasher?
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.
How do I fix the Motor Low Current error on my Maytag dishwasher?
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.
Can I still use my Maytag dishwasher when the Motor Low Current error is active?
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.
How much does it cost to fix a Motor Low Current error on a Maytag dishwasher?
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.
How do I check motor resistance to diagnose the Motor Low Current error on a Maytag dishwasher?
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.
