The short answer
A washer that will not drain has a restriction far more often than a failed pump. A pump that has died is silent; a pump fighting a blockage hums, strains and leaves the tub full, and that distinction is the whole diagnosis. Listen during the drain step. A hum with no water leaving means the pump is powered and obstructed; complete silence means the pump is not being driven at all. On a Staber washer the cause that ranks first is pump filter or coin trap blocked.
What you observe
- Water standing in the drum at the end of the cycle — The tub never emptied, so the spin never ran.
- The machine hums during the drain step but the level does not fall — A powered pump working against a restriction or a jam.
- The drain step is completely silent — The pump is not being driven at all.
- NEAR MISS — the machine drains but leaves clothes soaking wet — That is a spin fault, usually imbalance, rather than a drain fault.
Causes, most likely first on a Staber washer
- Pump filter or coin trap blocked — Lint, coins, hair grips and tissue build into a mat in the filter chamber until the pump can no longer draw through it. It ranks first on a Staber washer because these cabinets are built to a price, so the simple wear items go first and they go often.
- Foreign object jamming the pump impeller — A coin or an underwire reaches the impeller and locks it, so the motor buzzes while nothing moves. Second on this platform: it produces a buzz with no flow, which is a different sound from a healthy pump and from a dead one.
- Drain hose kinked, or pushed too far into the standpipe — The hose is crushed behind the machine when it is pushed back, or inserted so deep into the standpipe that it siphons and blocks. Ranked here because the hose is the part that moves every time the machine is moved, so it is the likeliest thing to have changed.
- Drain pump motor failed — A pump that has failed electrically is silent during the drain step and leaves a full tub with no other symptom. Last, and the reason to work down the list rather than guess: silence during the drain step is the signature, and it is the point where owner checks end.
Check in this order, and why
- Open the filter access at the bottom front and look at what comes out — It is the commonest cause and it needs no tools on most machines.
- Listen during the drain step for a buzz with no water movement — A buzz without flow is a jam, not a failed motor.
- Pull the machine forward and follow the drain hose end to end by hand — A crush point or an over-deep insertion is found in a minute.
What an owner can safely check
- Put a tray down, open the filter, clear it by hand and refit it squarely — Expect water: the chamber holds a good deal of it.
Tools: shallow tray, towel, gloveAbout 25 min
- With the power off, open the filter and turn the impeller by hand to check it spins freely — Anything hard you find in there is the cause.
Tools: shallow tray, towel, gloveAbout 20 min
- Straighten the hose, re-clip it, and set it no deeper into the standpipe than the marked depth — Do not tape the hose into the standpipe: it needs an air break.
Tools: torchAbout 15 min
- STOP HERE — the next check means a meter, a panel, or both — The ranking above tells you what to ask for; it does not make the remaining tests owner work.
Before you open anything
Safety
Unplug the machine or switch off its breaker before opening the filter, and shut both taps before disconnecting anything. Put a tray and towels down first — the filter chamber releases far more water than people expect.
When to call a technician
Call when the filter and the hose are clear and the drain step is silent, or when water backs up out of the standpipe — the first needs a meter and the second needs a plumber. On a mechanically controlled machine the repair is usually a discrete part rather than a board, which makes it worth quoting properly instead of writing the machine off.

What this page does not cover
This is the generalized page for a Staber washer. It does not carry anything model-specific: no part numbers, no wiring colours, no panel sequence and no torque figures, because those differ between families sold under the same badge. Where a family- or model-level page exists it is linked above, and it is the more specific answer of the two.
