Admiral Dishwasher White Film on Glasses: Hard Water Fix... | appliancefaults.com

Technical Background:

The dishwasher's MCU controls the water inlet valve, detergent dispenser, rinse aid dispenser, and heating element. Insufficient rinse aid or inadequate water temperature prevents proper drying and mineral removal, leading to film. A faulty water softener exacerbates the issue by not reducing the mineral content of the water.

Symptoms:

US homeowner observes a white, cloudy film on glasses and dishes after running the Admiral dishwasher, especially noticeable in hard water areas. The film doesn't easily wipe off and reappears after subsequent washes.

Possible Causes:

Hard water minerals (calcium, magnesium)
Low rinse aid dispenser level
Incorrect detergent usage
Low water temperature
Malfunctioning water softener (if applicable)
Clogged spray arms

Solution:

1

Test water hardness: Use a hard water test strip to determine the grains per gallon (GPG). Over 7 GPG is considered hard.
2

Increase rinse aid: Fill the rinse aid dispenser to the maximum level and adjust the dial to a higher setting.
3

Use appropriate detergent: Use a dishwasher detergent specifically formulated for hard water. Check the phosphate content.
4

Increase water temperature: Verify the water heater is set to at least 120°F (49°C). Run hot water at the sink before starting the dishwasher.
5

Inspect and clean spray arms: Remove the spray arms and check for clogs. Use a small wire or toothpick to clear any obstructions.
6

Check water softener (if applicable): Ensure the water softener is functioning correctly and has sufficient salt. Regenerate the softener according to the manufacturer's instructions.
7

Run a cleaning cycle: Use a dishwasher cleaner like Affresh or Lemi Shine according to the package directions.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before performing any repairs. Verify the power is off with a multimeter before touching any internal components. High voltage is present inside the appliance. Lock Out / Tag Out procedures are mandatory.

Prevention:

Regularly clean the dishwasher filter, use a dishwasher cleaner monthly, and check/replenish the rinse aid dispenser. Ensure the water softener (if present) is properly maintained with sufficient salt and regular regeneration cycles.

Expert Tip:

Try adding 1/2 cup of white vinegar to the bottom of the dishwasher before running a cycle. The vinegar helps dissolve mineral buildup. Some Admiral dishwashers have a diagnostic mode; consult the service manual for the specific key sequence to access error codes.

Frequently Asked Questions

•How do I test the water inlet valve for proper operation?

Disconnect power. Use a multimeter to check for continuity across the valve's solenoid terminals. If there's no continuity, the valve is likely faulty. Reconnect power and test for 120V AC at the valve terminals during the fill cycle. No voltage indicates an issue with the control board or wiring.

•What are the typical settings for the rinse aid dispenser?

Rinse aid dispenser settings usually range from 1 to 6. Start with a setting of 3 and adjust based on the severity of the filming. Higher settings dispense more rinse aid.

•How can I tell if my water softener is working effectively?

Use a hard water test strip to measure the water hardness before and after the water softener. The softened water should have a significantly lower GPG (grains per gallon) value than the unsoftened water.
