Amana Washer Error Code Int: Cycle Interrupted... | appliancefaults.com

Technical Background:

The 'Int' error code on an Amana washer indicates an interruption in the wash cycle. This can be due to a loss of power, a problem with the lid switch circuit, or a failure within the motor control unit (MCU). The MCU monitors various inputs, including the lid switch, motor speed, and water level, to ensure the cycle progresses correctly. If any of these inputs are disrupted, the MCU will trigger the 'Int' error.

Symptoms:

The Amana washer displays the error code 'Int' on the control panel and the wash cycle is interrupted. The washer may stop mid-cycle, fail to start, or display the error code immediately after starting.

Possible Causes:

Power interruption during the cycle.
Lid switch malfunction.
Motor control unit (MCU) failure.
Wiring harness issue between the MCU and other components.
Water inlet valve problem causing insufficient water fill.
Drain pump malfunction causing slow draining.

Solution:

1

Unplug the washer from the outlet.
2

Check the breaker panel for tripped breakers. Reset if necessary.
3

Inspect the lid switch for proper operation. Use a multimeter to test for continuity when the lid is closed. Should read 120V AC with lid closed.
4

Examine the wiring harness between the MCU, motor, and lid switch for any loose connections or damaged wires. Use a wiring diagram for reference.
5

Test the water inlet valve for proper function. Ensure it receives 120V AC when the washer calls for water.
6

Check the drain pump for obstructions. Test the drain pump for 120V AC during the drain cycle.
7

If the above steps do not resolve the issue, suspect a faulty MCU. Replacing the MCU may be necessary.

Safety Warning:

Disconnect the power to the washer before performing any repairs. High voltage is present within the appliance. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization.

Prevention:

Avoid overloading the washer. Ensure the power cord is securely plugged into a dedicated outlet. Regularly inspect the water supply hoses for leaks or damage. Check the drain hose for clogs.

Expert Tip:

Some Amana washers have a diagnostic mode. To access it, press and hold the Start/Pause button for 3 seconds, then simultaneously press and hold the Cycle Selection button for 3 seconds. This may display more specific error codes or allow for component testing.

Frequently Asked Questions

•What is the resistance reading I should expect from a functioning lid switch?

A functioning lid switch should have near-zero resistance (continuity) when the lid is closed and infinite resistance (open circuit) when the lid is open. Use a multimeter on the ohms setting.

•How do I test the motor control unit (MCU) without replacing it?

Testing an MCU requires advanced diagnostic skills and a thorough understanding of the washer's circuitry. You can check for proper voltage supply to the MCU and verify that the input signals from the lid switch and other sensors are present. If these are correct, the MCU is likely faulty.

•Where can I find a wiring diagram for my Amana washer model?

A wiring diagram is usually included in the service manual for your specific Amana washer model. You can often find these manuals online by searching for the model number and "service manual". The diagram is also often affixed to the inside of the washer cabinet.
