The short answer
The usual answer on this unit is a kinked, crushed or badly positioned drain hose, with a blocked standpipe or household waste next. Both are reachable without moving the machine. Most of this page is owner work and none of it needs the machine opened up.
The symptoms, and their near misses
- Nothing at all happens at the drain phase — No pump noise, which is a different fault from a blocked one.
- It drains but will not spin — The machine will not spin on a full tub, so this is still a drain problem.
- NEAR MISS: water is on the floor rather than in the drum — Read the water-leak page for this unit instead.
Causes, most likely first on this unit
- A kinked, crushed or badly positioned drain hose — The hose is crushed against the wall when the machine is pushed back, or it is pushed so far down the standpipe that it siphons. Either way the water does not leave. It leads the list on a Wascomat washing machine because it is disturbed every time the machine is moved, which is precisely what happens before this fault appears.
- A blocked standpipe or household waste — Lint and detergent scale build up in the standpipe over years. Second on this unit, because if the sink beside it is also slow, the appliance is not the problem at all, and that is a free test.
- A blocked pump filter or coin trap — The filter behind the flap at the bottom front catches everything that leaves a pocket. Third, once the two above are clean: it is the first restriction in the drain path, it is designed to be opened by the owner, and on most machines it has never once been cleaned.
- A failed drain pump — Complete silence at the drain phase, with the filter clear and the impeller free, means the pump is not being driven or has failed. Last on purpose: everything above it produces the same full drum at no cost, and it is genuinely the least common.
Check in this order, and why
- Pull the machine out and follow the hose to the standpipe — A kink, a crush or a hose pushed too deep are all visible at once.
- Pour a bucket of water down the standpipe and watch it go — Slow there means plumbing, and no amount of appliance work will help.
- Open the flap at the bottom front and look at the filter — A packed trap explains a slow drain and a dead one equally well.
Owner-side checks, step by step
- Pull the machine forward and check the drain hose for kinks and crushing, and that it enters the standpipe only a hand's depth — It must not sit in standing water at the end.
Tools: a torchAbout 20 min
- Take the hose out of the standpipe and pour a bucket of water down it — If it backs up, the blockage is the plumbing.
Tools: a bucketAbout 15 min
- STOP AT THIS POINT if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.

Safety
Cut the power at the breaker and close both taps before starting. Expect water at the filter and expect it to be hot on a machine that has just run, so open it in stages over a tray. Never force a locked door with water still in the drum, and never tape or wedge a lid switch to get a cycle to run.
The line between a fix and a service call
Call once the filter, the drain hose, the standpipe and the impeller are all clear and there is still silence at the drain phase. Call sooner if the machine trips a breaker, smells hot, or has a door locked shut on a full drum that will not empty through the filter.

What is deliberately not on this page
This page covers the Wascomat washing machine as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: pump part numbers, hose lengths, standpipe height figures and any wiring detail, all of which differ by family and belong on the page for that family.
