Speed Queen UE Error Code — What It Means
The Speed Queen UE error code (also displayed as UB or Er. UB) indicates an unbalanced load fault. The washer has detected a severe imbalance in the tub during the spin cycle and stops to protect the machine from damage. You will typically see excessive shaking or the washer will refuse to complete the spin cycle. This code is a safety feature designed to prevent the machine from damaging itself or the surrounding area when the load is not distributed evenly.
Common Causes
- Single bulky item or clumped laundry Large items like blankets or sheets can wrap around themselves, or mixed loads can ball up on one side of the tub during spin, creating an unbalanced condition.
- Washer not level or unstable floor If the cabinet rocks or the leveling feet are loose, or if the washer sits on flexible flooring, the machine cannot compensate for normal spin dynamics and trips the unbalance fault.
- Washer touching wall or cabinet Contact with surrounding surfaces during spin can cause excessive vibration that the control interprets as a dangerous imbalance.
- Worn suspension or shock absorbers If the code appears repeatedly on properly distributed loads, the suspension components may no longer dampen tub movement correctly.
- Faulty unbalance switch or sensor A defective switch or damaged wiring connector can send false imbalance signals to the control board even when the load is balanced.
Step-by-Step Fix
- Stop the cycle and redistribute the load. Open the lid, manually separate any clumped items, and spread the laundry evenly around the tub. Remove one or two items if the load is too large or add a few towels if the load is very small.
- Verify the washer is level and stable. Place a torpedo level on top of the cabinet in both directions and adjust the leveling feet until the washer sits flat without rocking. Tighten the lock nuts on the feet once level.
- Check clearance around the washer. make sure at least one inch of space on all sides so the cabinet cannot contact walls or cabinets during spin.
- Run a test load with mixed items. Use a small to medium load of mixed towels and garments, then run a spin cycle. If the error reappears on this balanced test load, the problem is mechanical rather than loading related.
- Inspect the tub suspension and shocks. With power off, manually rock the tub and watch for excessive play or weak damping. Look for leaking fluid on shock absorbers or cracked suspension springs.
- Examine the unbalance switch and wiring. Locate the unbalance switch (typically near the tub or suspension mounting) and check the harness connector for looseness, corrosion, or damaged pins. Wiggle the connector while observing for intermittent faults.
- Replace faulty components and retest. If you find worn shocks or a defective unbalance switch, replace the part and run a drain and spin test cycle to confirm stable high-speed operation without the error code.
Parts Often Needed
| Part | Notes |
|---|---|
| Speed Queen unbalance switch | Amazon | Required if the switch tests faulty or the connector shows damage after inspection. |
| Speed Queen suspension shock absorbers | Amazon | Sold individually or in sets. Replace if leaking fluid or weak damping is observed. |
| Unbalance switch wiring harness | Amazon | Order if the connector or wire insulation is cracked or corroded beyond cleaning. |
When to Call a Pro
Call a professional if the error persists after you have redistributed the load, leveled the washer, and ensured proper clearance. Repeated UE codes on properly balanced test loads indicate a suspension or sensor problem that requires disassembly and component replacement. A qualified technician can accurately diagnose whether the unbalance switch, wiring harness, or shock absorbers need replacement and has the tools to test tub movement under load. If your washer is still under warranty, contact Speed Queen or an authorized service provider before attempting internal repairs.
