Alliance SWNBX2PP112TW02 washer Parts

Common problems we see with the Alliance SWNBX2PP112TW02 washer include not draining or spinning, leaking, excessive vibration, and lid or control-related issues. Many are caused by clogs, worn drive components, or sealing problems; targeted checks and the right replacement part usually restore normal operation.

Most common symptoms and what they usually mean

• Won’t drain or leaves water in the tub: drain path restriction, pump issue, or a slipping/worn belt.
• Won’t spin or spins weakly: belt/pump drive wear, drive block wear, or load balance problems.
• Leaks: tub gasket wear, hose connection issues, or a failing seal/gasket.
• Loud noise during agitation/spin: worn drive components, loose hardware, or something rubbing the cabinet.
• Excessive vibration or walking: unlevel washer, weak suspension, or overloaded/unbalanced loads.

Quick checks we recommend before replacing parts

1. Power reset: unplug for 2 minutes, then retry a cycle.
2. Load and leveling: redistribute the load; confirm all feet are firmly on the floor.
3. Drain basics: check the standpipe height and make sure the drain hose is not kinked or crushed.
4. Leak tracing: run a small fill and watch where the first drip appears (front, bottom, or rear).
5. Listen for clues: a humming motor with no movement often points to a drive or pump load issue.

Parts that commonly solve these problems

If symptoms match, these model-compatible parts are common fixes:

• Drain/spin issues tied to belt and pump drive: speed queen belt and pump kit - includes items 16 and 18 (38174 belt) RB150003
• Leaks at the tub or sealing surfaces: speed queen washer tub gasket 36425 and speed queen gasket 39122
• Spin/drive engagement problems: speed queen washer drive block 39508P

In an Alliance washer model SWNBX2PP112TW02, the parts that fail most often are the ones that move water, transfer power, or seal against leaks. In real-world repairs, we most commonly see issues with the drain system, drive components, lid/lock hardware, and tub seals.

Most common washer parts that fail (and what you notice)

• Drain and pump-related parts: washer won’t drain, drains slowly, or leaves water in the tub
• Drive system parts (belt, drive block, gear case): won’t spin, weak spin, burning rubber smell, or loud squealing/grinding
• Seals and gaskets: water leaks under the washer or around the tub area
• Lid hardware and safety/lock components: lid won’t close correctly, won’t start, or stops mid-cycle
• Control components: dead panel, erratic cycle behavior, or intermittent operation

Model-relevant examples you can check first

These are common failure points that match parts available for SWNBX2PP112TW02:

• If it won’t spin or drains poorly, inspect the belt and pump drive system; the speed queen belt and pump kit - includes items 16 and 18 (38174 belt) RB150003 is a typical fix when the belt is worn or the pump drive is compromised.
• If you have leaks, tub and cabinet sealing surfaces are key; a worn gasket such as the speed queen washer tub gasket 36425 is a common culprit.
• If the washer agitates/spins poorly or bangs, the speed queen washer drive block 39508P is one part that can wear and cause drive slippage.

Quick symptom-to-part checklist

Symptom	Most likely part area	What to do first
Won’t drain / slow drain	Pump, belt, hoses, clamps	Check for clogs, then inspect belt/pump drive
Won’t spin / loud squeal	Belt, drive block, gear case	Look for belt wear, then check drive engagement
Water on floor	Tub gasket, other gaskets, hose connections	Inspect gasket surfaces and hose clamps
Lid won’t close right	Lid hinge/bearing, lid alignment	Check hinge play and lid alignment

Why it matters

Catching a failing belt, gasket, or drive component early helps prevent secondary damage (like water damage from leaks or extra wear on the gear case and motor). It also keeps cycle times and spin performance consistent.
