Amana Washer Out of Balance Error: Troubleshooting Guide... | appliancefaults.com

Technical Background:

The Washer's Main Control Unit (MCU) monitors drum movement via an accelerometer or load sensor. When excessive vibration or imbalance is detected, the MCU triggers the out-of-balance error to prevent damage to the machine. The voltage signal from the sensor is processed by the MCU, and if the signal exceeds a programmed threshold, the error is displayed.

Symptoms:

The homeowner reports that the Amana washer displays an out-of-balance error message on every load, regardless of the size or weight of the laundry. The drum may shake violently, and the cycle may stop prematurely.

Possible Causes:

Worn suspension rods
Damaged tub dampening straps
Defective basket drive
Faulty load sensor
Unlevel washer system
Blocked drain pump

Solution:

1

Unplug the washer from the 120V AC outlet. Always verify power is off using a non-contact voltage tester.
2

Access the washer's internal components by removing the top or front panel, typically secured with screws (using a 1/4-inch nut driver).
3

Inspect suspension rods for wear or breakage. Replace if necessary. These rods are crucial for stabilizing the wash tub.
4

Check tub dampening straps for damage or detachment. Secure or replace as needed. Straps dampen tub oscillations.
5

Examine the basket drive for wear, looseness, or damage. Tighten or replace if required, using a socket set. A worn basket drive can cause imbalance.
6

Verify washer is level using a bubble level. Adjust legs as needed. An unleveled machine will exaggerate any imbalance.
7

Check the load sensor using a multimeter. Refer to the service manual for resistance values or voltage output. A faulty sensor can give false readings.
8

Reconnect power and test washer operation. Run a small test load to observe drum behavior.

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage is present when the machine is plugged in. Follow Lock-Out/Tag-Out (LOTO) procedures to prevent accidental electrocution.

Prevention:

Periodically inspect suspension components for wear. Avoid overloading the washer. Ensure the machine is level and stable. Use HE detergent.

Expert Tip:

Enter the washer's service mode (Consult the service manual for the specific key sequence - this often involves pressing a combination of buttons on the control panel). Run a calibration cycle to reset the load sensor and balance parameters. This can sometimes resolve persistent out-of-balance errors after repairs.

Frequently Asked Questions

•What are the correct resistance readings for the load sensor on this model?

Refer to the Amana washer's service manual for the specific resistance values for the load sensor. These values will vary depending on the model and sensor type. Typically, you'll measure resistance across the sensor's terminals with a multimeter while the tub is empty and again with a known weight inside.

•How do I properly level the washer on a sloped floor?

Use shims under the washer's legs to compensate for the slope. Adjust the legs to achieve a level surface, then insert shims to maintain that level. Secure the shims to prevent them from shifting.

•Where can I find replacement suspension rods for this Amana washer?

You can find replacement suspension rods at appliance parts retailers, both online and in local stores. Provide the washer's model number to ensure you get the correct parts. Search online using the model number and 'suspension rods'.
