Admiral Dishwasher Clean Light Blinking 7 Times:... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) monitors various sensors and components. The blinking clean light indicates the MCU has detected a fault in the water fill or drain cycle. This error code is often associated with incorrect water levels or flow, causing the MCU to halt the cycle. Voltage paths to the inlet valve, drain pump, pressure switch, and flow meter need to be verified.

Symptoms:

The Admiral dishwasher's clean light is blinking 7 times repeatedly. The dishwasher may not fill with water, may not drain properly, or may not start a cycle.

Possible Causes:

Water inlet valve malfunction
Flow meter issues
Pressure switch failure
Drain pump obstruction
Control board failure

Solution:

1

Disconnect power at the breaker panel. Verify 0V AC at the dishwasher receptacle using a multimeter.
2

Inspect the water inlet valve. Using a 5/16-inch nut driver, remove the valve and check for debris or damage. Test the valve's solenoid for continuity; it should read between 500-1500 ohms.
3

Check the flow meter. Located near the inlet valve, examine it for obstructions. A faulty flow meter can cause incorrect water level readings.
4

Examine the pressure switch. With the power off, disconnect the pressure switch and test for continuity when the tub is empty.
5

Inspect the drain pump. Clear any obstructions. Test the drain pump motor for continuity; typical readings are 10-20 ohms.
6

Check the wiring harness and connections to the control board for any signs of damage or corrosion. Repair or replace as needed.
7

If all components check out, the control board may be faulty and require replacement.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before attempting any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization of the circuit. High voltage is present in the control board and wiring. Exercise caution when working around electrical components.

Prevention:

Regularly clean the dishwasher filter to prevent drain pump obstructions. Ensure adequate water pressure to the inlet valve. Use a dishwasher cleaner monthly to prevent buildup and maintain proper operation.

Expert Tip:

Some Admiral dishwashers have a service mode. To enter service mode, press and hold the 'Start/Reset' button for 5 seconds, then press the 'High Temp Wash' button twice, followed by the 'Air Dry' button once. This will allow you to run diagnostic tests and check individual components.

Frequently Asked Questions

•What is the correct ohm reading for the water inlet valve solenoid?

The water inlet valve solenoid should typically read between 500 and 1500 ohms.

•Where is the flow meter located in the dishwasher?

The flow meter is usually located near the water inlet valve, often connected to the inlet hose.

•How do I check the pressure switch for continuity?

Disconnect the pressure switch and test for continuity with a multimeter when the dishwasher tub is empty. It should typically show continuity in the empty state and open when the water level reaches a certain point.
