Admiral Dishwasher Cycle Resetting: Troubleshooting... | appliancefaults.com

Technical Background:

Dishwashers use a Main Control Unit (MCU) to manage the wash cycle. The MCU relies on sensor inputs and timing to sequence through wash, rinse, and dry stages. A cycle reset suggests an interruption in the MCU's logic or power supply. Voltage fluctuations or component failures can trigger unexpected resets.

Symptoms:

The Admiral dishwasher starts a cycle, runs for a short period, and then unexpectedly resets back to the beginning or shuts off completely. There are no error codes displayed, and the unit appears to be randomly restarting.

Possible Causes:

Faulty door latch switch
Defective control board (MCU)
Wiring harness issue or loose connection
Overheating motor
Stuck or shorted keypad button
Water inlet valve malfunction

Solution:

1

Disconnect power to the dishwasher at the breaker panel.
2

Inspect the door latch switch for damage or continuity issues. Use a multimeter to test for continuity when the latch is engaged (should be closed circuit) and disengaged (open circuit).
3

Check the wiring harness connections to the control board, motor, and other components. Look for loose or corroded terminals.
4

Examine the control board for any signs of burning or damage. Specifically, check the relay contacts and capacitors.
5

Test the water inlet valve using a multimeter for proper coil resistance (typically around 500-1500 ohms). Also, ensure the valve is not stuck open or closed.
6

Measure the motor windings for shorts to ground. Resistance to ground should be infinite. Winding resistance should be as specified on the motor’s nameplate.
7

If all components check out, consider replacing the control board (MCU).

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before performing any diagnostics or repairs (Lock Out/Tag Out procedure). Dishwashers operate on 120V AC, which can cause serious injury or death. Use caution when working around electrical components.

Prevention:

Regularly clean the dishwasher filter and spray arms to prevent blockages that can strain the motor. Periodically inspect the wiring harness for any signs of damage or wear. Run a dishwasher cleaner through the unit every month to remove buildup.

Expert Tip:

Some Admiral dishwashers have a service mode. Check the tech sheet behind the kick panel. If the dishwasher has service mode, it can run diagnostics and show error codes. Activate the service mode, typically by pressing a combination of buttons (e.g., Hi-Temp Wash and Heated Dry) simultaneously for a few seconds. This can reveal hidden error codes or allow you to run a diagnostic cycle.

Frequently Asked Questions

•How do I access the control board on my Admiral dishwasher?

Typically, you'll need to remove the outer door panel and the inner door panel. The control board is usually located behind the inner door panel or at the base of the unit. Refer to your model's service manual for specific instructions.

•What voltage should I expect to see at the door latch switch when the door is closed?

You should measure 120V AC at the input side of the door latch switch when the dishwasher is connected to power and the breaker is on. The output side will only show 120V AC when the door is fully closed and the latch is engaged, completing the circuit.

•Where can I find a replacement control board for my Admiral dishwasher?

You can find replacement control boards at appliance parts retailers like AppliancePartsPros, RepairClinic, or through the manufacturer's website. Make sure to have your dishwasher's model number handy to ensure you order the correct part.
