First, drain the tub
Bail water out with a bowl into a bucket. You can't service the pump with water still in the drum.
Three things to check
- Drain hose behind the washer — is it kinked or pushed in too far? It should curve into the standpipe, not jam into it. The standpipe needs a 1–2" air gap or the washer siphons.
- Pump filter (front-loaders) — small access door bottom-front of the machine. Have a towel and a shallow tray ready. Spin out the trap clockwise. Coins, hair pins, and lint come out.
- Lid switch (top-loaders) — if the switch is broken, the spin cycle won't engage. Tap it firmly. If that wakes the cycle, the switch needs replacing (~$25 part).
When to call service
- Burning smell from underneath = drive belt or motor coupling.
- Pump runs but no water moves = bad pump impeller.
