Amana Dishwasher: Troubleshooting Detergent Pods Not... | appliancefaults.com

Technical Background:

The Dishwasher's Main Control Unit (MCU) controls the dispenser release based on the wash cycle timing. Voltage is sent to the dispenser solenoid at the appropriate time to release the detergent. If the solenoid fails, or if the voltage path is interrupted, the dispenser door will not open. Low water temperature reduces the detergent's ability to dissolve.

Symptoms:

Homeowners report that the detergent pod is left intact in the dispenser after the wash cycle, indicating it's not dissolving properly. Dishes may not be clean, and there may be residue on the dishes.

Possible Causes:

Low water temperature.
Clogged spray arms preventing proper water circulation.
Malfunctioning detergent dispenser (door not opening or solenoid failure).
Overloading the dishwasher, which blocks water flow.
Using old or hardened detergent pods.
Low water pressure affecting spray arm performance.

Solution:

1

Verify the incoming water temperature. Use a thermometer at the kitchen faucet; it should be at least 120°F. Adjust the water heater if necessary.
2

Inspect and clean the spray arms. Remove them and use a small wire or toothpick to clear any clogs in the spray nozzles.
3

Check the dispenser door mechanism. Ensure it opens and closes freely. If it's sticky, try cleaning it with a damp cloth and mild detergent. If the problem persists, the dispenser assembly may require replacement.
4

Check the dispenser solenoid. Using a multimeter, test for continuity across the solenoid terminals during the wash cycle. If there's no continuity, replace the solenoid.
5

Check the water inlet valve screen for debris that might be restricting water flow. Clean the screen if necessary.
6

Run a cleaning cycle using a dishwasher cleaner to remove mineral deposits.
7

If the detergent dispenser is irreparably damaged, replace the entire dispenser assembly. Use a 1/4-inch nut driver to remove the mounting screws.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should always be followed. High voltage (120V AC) is present in the control panel and near the dispenser solenoid. Exercise caution when working in these areas.

Prevention:

Run hot water at the kitchen sink before starting the dishwasher. Regularly clean the dishwasher filter and spray arms. Use fresh detergent pods and store them in a cool, dry place.

Expert Tip:

Many Amana dishwashers have a diagnostic mode. Press and hold the 'Start/Cancel' button for 5 seconds, then press the 'High Temp Wash' and 'Heated Dry' buttons simultaneously. This may display error codes or allow you to test individual components.

Frequently Asked Questions

•How do I access the dispenser solenoid to test it?

You'll typically need to remove the inner door panel of the dishwasher. This usually involves removing several screws around the perimeter of the panel. Once the panel is removed, you should be able to access the detergent dispenser and its solenoid. Be careful not to damage any wiring when removing the panel.

•What is the correct ohm reading for a functional dispenser solenoid?

A typical dispenser solenoid should read between 200 and 500 ohms. However, it's best to consult the service manual for your specific Amana dishwasher model for the exact resistance range.

•My water temperature is fine, and the spray arms are clean. What else could prevent the pod from dissolving?

If the water temperature and spray arms are good, focus on the water pressure feeding the dishwasher. Low water pressure can significantly reduce the effectiveness of the spray arms and prevent the detergent from dissolving properly. Check the water supply valve under the sink to ensure it's fully open. Also, inspect the inlet valve screen on the dishwasher itself for any blockages.
