What are the symptoms of error code UC?

Washer stops mid-cycle with UC on the display, Washer begins to spin but suddenly aborts, Washer shakes or vibrates excessively before stopping, Washer drains unexpectedly and halts, Washer may attempt to restart spin multiple times

What causes error code UC?

Worn or slipping clutch assembly, Unbalanced load causing erratic torque readings, Worn tub bearings allowing basket wobble, Motor unable to maintain controlled RPM, Loose or damaged wiring to the motor controller, Control board misreading torque or speed feedback, Objects trapped between basket and tub

How do I fix error code UC?

Redistribute the load and restart the cycle., Remove heavy or waterlogged items and spin separately., Rotate the basket by hand --- it should spin smoothly without wobble., Inspect the clutch for slipping, wear, or contamination., Check for items trapped between the basket and tub., Inspect tub bearings for grinding or excessive play., Test motor windings and wiring harness connections., If mechanical components test good, inspect the control board.

Maytag Washer - UC Error Code

The washer detected an uncontrolled or unsafe spin condition.

Meaning

The washer detected an uncontrolled or unsafe spin condition.

The Maytag UC error code appears only on Neptune TL washers (FAV6800AWW and FAV9800AWW). It indicates that the washer detected an uncontrolled spin condition --- meaning the basket speed increased or behaved unpredictably outside the expected torque and RPM profile. The Neptune TL platform uses torque feedback, clutch monitoring, and motor speed sensing instead of a traditional tachometer. If the control detects unexpected acceleration, slipping, or loss of basket control, it immediately stops the cycle and displays UC.

Symptoms

Washer stops mid-cycle with UC on the display
Washer begins to spin but suddenly aborts
Washer shakes or vibrates excessively before stopping
Washer drains unexpectedly and halts
Washer may attempt to restart spin multiple times

Causes

Worn or slipping clutch assembly
Unbalanced load causing erratic torque readings
Worn tub bearings allowing basket wobble
Motor unable to maintain controlled RPM
Loose or damaged wiring to the motor controller
Control board misreading torque or speed feedback
Objects trapped between basket and tub

Step-by-Step Fixes

Redistribute the load and restart the cycle.
Remove heavy or waterlogged items and spin separately.
Rotate the basket by hand --- it should spin smoothly without wobble.
Inspect the clutch for slipping, wear, or contamination.
Check for items trapped between the basket and tub.
Inspect tub bearings for grinding or excessive play.
Test motor windings and wiring harness connections.
If mechanical components test good, inspect the control board.

Safety Notes

Disconnect power before accessing the clutch, bearings, or motor.
Do not continue running the washer if it shakes violently.
Avoid washing single heavy items without balancing items.

Model-Specific Notes

UC is most commonly caused by a slipping clutch or failing tub bearings. Because the Neptune TL relies heavily on torque feedback, even small mechanical inconsistencies can trigger UC. If the basket wobbles or the clutch slips under load, the control interprets this as an unsafe spin condition.
