Amana Dishwasher: Accessing Soft Water Settings in the... | appliancefaults.com

Technical Background:

The dishwasher's MCU (Microcontroller Unit) reads the signals from the water hardness sensor (or receives manual user input) to adjust the amount of rinse aid dispensed and the cycle's water temperature. Incorrect settings can lead to poor washing performance. Voltage paths connect the sensor to the MCU on the control board.

Symptoms:

The homeowner may observe excessive spotting or filming on dishes, even with detergent, indicating an improper water hardness setting. If the dishwasher has a salt dispenser, the low salt indicator might illuminate prematurely or excessively.

Possible Causes:

Incorrect water hardness setting.
Faulty salinity sensor (if equipped).
Software glitch in the control board.
Incorrectly calibrated water softener.
Mineral buildup affecting sensor readings.

Solution:

1

Turn off the Amana dishwasher by pressing the power button.
2

Locate the specific button sequence for accessing the service or configuration menu. Common sequences involve pressing and holding two buttons simultaneously (e.g., 'High Temp' and 'Start/Resume') for 3-5 seconds until the display changes.
3

Once in the service menu, use the 'Cycle Select' or 'Options' buttons to navigate to the 'Water Hardness' or 'Soft Water' setting.
4

Check your water hardness level. If you're using a water softener, the setting should be low (0-6 grains per gallon). If you have hard water, adjust accordingly based on your local water test results.
5

Use the 'Start/Resume' button to confirm the new setting. The display should indicate that the setting has been saved.
6

Exit the service menu, usually by pressing the power button or a designated 'Exit' button.
7

Run a test cycle to ensure the new settings are implemented.

Safety Warning:

Disconnect power to the dishwasher at the breaker panel before attempting any repairs or adjustments beyond the user interface. High voltage (120V AC) is present in the control board and wiring. Lock Out/Tag Out (LOTO) procedures should be followed.

Prevention:

Periodically check and adjust the water hardness setting based on your local water supply. Clean the salinity sensor (if applicable) with a mild vinegar solution to prevent mineral buildup. Ensure your home's water softener is functioning correctly.

Expert Tip:

If the soft water setting consistently reverts to the default, the control board may need replacement. Some models allow you to initiate a factory reset via the service menu; consult the service manual for the exact procedure.

Frequently Asked Questions

•Where can I find the specific button sequence for accessing the service menu on my Amana dishwasher?

The button sequence is often found in the dishwasher's user manual or service manual. You can also search online using your specific model number to find instructions or videos demonstrating the process.

•How do I test the salinity sensor in my dishwasher?

Testing the salinity sensor typically involves using a multimeter to measure resistance or voltage across the sensor's terminals. Refer to the service manual for the correct testing procedure and expected values. You may need to access the sensor by removing lower access panels.

•My dishwasher doesn't have a display. How do I adjust the soft water setting?

Some Amana dishwashers without digital displays use a series of indicator lights and button presses to configure settings. The procedure will be specific to your model, so consult your user manual for instructions. The soft water setting may be indicated by a specific light pattern.
