The short answer
The usual answer on a SMAD washer is the installation made behind the panel. The drain pump itself is on the list below, and it is the least likely thing on it. On a machine set into cabinetry the ranking shifts toward the install: check whether yours is enclosed on three sides, because a fault that is really the enclosure looks exactly like a fault in the appliance. The first 2 checks need no tools and no panel off, and the point where owner work stops is marked below.
What this looks like
- It drains but very slowly — A slow drain is a restriction rather than a blockage, and that changes which causes matter.
- The cycle ends with water still in the drum — The clearest version of this fault.
- The pump hums but nothing leaves — The motor is running and the water is not moving, which points at the impeller.
- NEAR MISS — water on the floor rather than in the drum — That is a leak and it has its own page.
Causes, most likely first on SMAD
- The installation made behind the panel — On a built-in the pipework and the cord run out of sight through the carcass, and every place the installer had to bend something to make it fit is a candidate that an owner would never think to look at. Ranked first on SMAD because of the kind of machine this is: an appliance set into a run is only as good as the enclosure and the connection made behind it, and neither is ever inspected.
- The pump filter and what is in it — The filter is there to catch coins, hair, buttons and lint before they reach the impeller, and it does its job until nobody empties it. A packed filter slows the drain to a trickle and then stops it. Ranked second — less common than the cause above, and the one most often mistaken for something expensive.
- The level sensing hose — The machine decides the tub is empty by air pressure in a small hose. A hose that has silted or trapped water reports a level that is not there, and the machine stops pumping while water is still in the drum. Third on SMAD: not rare, simply behind two checks that cost nothing.
- The drain pump itself — A machine that makes its usual pumping noise while nothing leaves is the more common version, and it usually means the impeller is jammed or broken rather than the motor. Ranked last, and the order matters most right here: this is the one item that changes what the repair costs.
Check in this order, and why
- First: Open the adjacent cabinet and look at the hose run — First on the list because the whole hookup is reachable from the next cupboard without moving the machine at all.
- Second: Open the filter flap at the front of the machine — It comes second because it is the only one that needs nothing but a towel.
- Third: Only after the visible drain path is known to be clear — It is last here because it can only be judged once every mechanical blockage has been excluded.
The checks you can do yourself
- Open the neighbouring cabinet and follow the hoses by eye and hand — Look for a hose bent hard around a carcass edge, a fitting that is not square, and any damp on the cabinet floor.
Tools: torchAbout 10 min
- Open the pump filter and clear it completely — Unplug the washer, lay a towel and a shallow tray down, unscrew the filter slowly to let water out in stages, then clear it and check the impeller turns.
Tools: shallow tray, towelAbout 30 min
- STOP HERE if the next step needs a meter on live terminals — Everything past this point needs test equipment and an appliance that is open. Call from here.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close both taps before undoing a hose, and put a tray and a towel down before opening a filter — what comes out is hot on some cycles. Never defeat the door lock to open a machine mid-cycle: that lock is holding a drum full of water.
When to call a technician
Stop at the first step needing a meter on live terminals, and call from there. Anything that needs the cabinet off, a meter on live terminals, or the drum assembly disturbed is a service call rather than an afternoon. Call sooner if the fault is getting worse rather than staying the same, because a cheap cause left alone is how an expensive one arrives.

What this page does not do is speak for one family or one model. It covers SMAD washers generally, and no family-specific page exists for it yet to send you to — when one is published, this page will link down to it and defer to it. Also absent by choice: part numbers, wiring detail and dismantling order.
