Admiral Dishwasher White Film on Dishes: Troubleshooting... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) governs wash cycles, including water intake, detergent and rinse aid dispensing, wash and rinse cycles, and water draining. The MCU energizes solenoids (120V AC) to open the water inlet valve and detergent/rinse aid dispensers. Thermistors provide water temperature feedback to the MCU. A pressure switch (or flow meter) confirms adequate water level. Voltage fluctuations or component failures can impact cycle execution.

Symptoms:

US homeowner observes a persistent white film on dishes after a complete wash cycle in their Admiral dishwasher, despite using rinse aid. The film appears on glassware, plates, and cutlery.

Possible Causes:

Hard water issues
Low water temperature
Detergent overuse or incorrect type
Faulty dispenser
Clogged spray arms
Circulation pump malfunction

Solution:

1

Test water hardness using a test strip. High hardness requires more detergent or a water softener.
2

Verify water temperature reaching the dishwasher. It should be at least 120°F. Check the hot water heater setting.
3

Reduce detergent amount or switch to a low-phosphate detergent. Follow detergent manufacturer's recommendations.
4

Inspect rinse aid dispenser for clogs or damage. Clean with warm water and a small brush. Verify proper dispensing.
5

Remove spray arms and check for clogs. Clean with a small wire or toothpick. Ensure free rotation.
6

Check circulation pump for proper operation. Listen for unusual noises. A multimeter can check continuity of the pump motor windings. (Expect around 10-20 ohms).
7

If all else fails, check the water inlet valve for proper operation. Make sure the valve is fully opening and supplying adequate water pressure.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. Some components carry 120V AC. Use caution and appropriate safety equipment.

Prevention:

Regularly clean the dishwasher filter. Use a dishwasher cleaner monthly. Periodically check and clean spray arms. Ensure proper water heater temperature. Adjust detergent usage based on water hardness.

Expert Tip:

On some Admiral models, you can initiate a diagnostic cycle by pressing the 'High Temp Wash' and 'Heated Dry' buttons simultaneously, followed by pressing 'Start'. Consult the service manual for specific model instructions. This cycle can reveal error codes.

Frequently Asked Questions

•What is the ideal water hardness level for a dishwasher?

Ideally, water hardness should be below 7 grains per gallon (gpg). A water softener is recommended for levels above this.

•How do I check the circulation pump for proper operation without disassembling it?

You can listen for unusual noises during the wash cycle. A failing pump may whine or sound labored. Also, check if the water pressure inside the dishwasher is adequate during operation. A weak spray pattern can indicate a pump issue.

•Where is the water inlet valve located on an Admiral dishwasher?

The water inlet valve is typically located at the lower front or side of the dishwasher, behind the kickplate. It's connected to the water supply line.
