Amana Washing Machine Error Code oL: Oversized Load... | appliancefaults.com

Technical Background:

The washing machine's MCU (Motor Control Unit) monitors the motor current and drum speed to detect load size and balance. The 'oL' error indicates the MCU has detected a condition exceeding the pre-programmed load limits. This can be due to genuine overload, a miscalibration of the sensing circuit, or physical obstruction.

Symptoms:

The washing machine displays the 'oL' error code on the control panel. The washer may stop mid-cycle, or the drum may not spin properly. The homeowner may report loading the washer as usual.

Possible Causes:

Overloading the washer with too many clothes.
Unbalanced load distribution within the drum.
Faulty load sensing system.
Obstruction in the drain pump restricting drum movement.
Defective motor control unit (MCU).
Worn or damaged drive belt (if applicable).

Solution:

1

Unplug the washing machine from the 120V AC outlet.
2

Manually redistribute the load evenly within the wash drum.
3

Remove some items to reduce the load size if it appears excessive.
4

Check the drain pump for obstructions (coins, lint, small objects) using a flat-head screwdriver to access the pump.
5

Inspect the drive belt (if applicable) for wear or damage and replace if necessary. Use a 5/16-inch socket to remove the rear panel if needed.
6

Plug the washer back in and run a test cycle with a smaller load.
7

If the error persists, test the load sensor wiring harness for continuity with a multimeter. Replace the sensor if needed.

Safety Warning:

Disconnect power to the washing machine at the breaker panel before performing any repairs. Use proper Lock Out Tag Out (LOTO) procedures to prevent accidental power-up. Be aware of potential electrical shock hazards when working with electrical components.

Prevention:

Avoid overloading the washing machine. Refer to the manufacturer's guidelines for maximum load capacity. Regularly check and clean the drain pump filter. Ensure proper leveling of the washing machine to minimize vibration and imbalance.

Expert Tip:

On some Amana models, entering service mode by pressing and holding specific button combinations (refer to the service manual) allows you to recalibrate the load sensing system. This may resolve the 'oL' error if the sensor is simply miscalibrated.

Frequently Asked Questions

•How do I access the drain pump on my Amana washing machine model?

Typically, the drain pump is accessible from the front lower panel. You will need to remove the screws holding the panel in place using a Phillips head screwdriver and then locate the drain pump assembly. Be prepared for water spillage.

•What is the typical load capacity for my Amana washing machine model?

Check the model number inside the washer lid or on the product sticker at the back of the appliance. Then, refer to the owner's manual for the specific load capacity, usually expressed in pounds (e.g., 10 lbs).

•Where is the load sensor located, and how can I test it with a multimeter?

The load sensor is typically integrated into the motor assembly or attached to the suspension system. Refer to the wiring diagram specific to your model. To test, disconnect the sensor wiring harness and use a multimeter set to ohms to check for resistance according to the service manual specifications.
