The short answer
Start with the standpipe height or a siphon: on a SMAD washer showing a cycle that starts and will not finish, that outranks everything else here, and control lock or a delay setting comes a long way behind it. Built-in machines change the ranking because the installation is part of the appliance: if yours sits in a run of cabinetry, the enclosure and the connection made behind it fail long before anything inside the cabinet does. Work down the order rather than across the list — the ranking is the page, and the cheapest answer arrives first.
What you are seeing
- It sits with very little water in the drum — A machine waiting on a fill level is waiting for water that is not arriving.
- Foam fills the door glass and does not clear — Suds smother the pump and stretch the cycle out.
- NEAR MISS — it will not start at all — A machine that never begins is a different fault and a different page.
Causes, most likely first on SMAD
- The standpipe height or a siphon — A drain hose set too low lets the machine siphon while it is filling, so it fills and drains at the same time and never reaches its level. The cycle then waits indefinitely. Ranked first on SMAD: it explains more of these calls than anything below, and it is the cheapest to exclude.
- A restriction on the drain — A machine will not advance past the drain step until it believes the tub is empty, and a partly-blocked filter, hose or standpipe slows the drain enough that it never gets there. Second, and worth doing while you are there: the same access settles both.
- 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. Placed here for what kind of machine this is rather than for a part: the enclosure is not the first thing to suspect here, but it is the thing that turns a small fault into a repeated one.
- Control lock or a delay setting — This is the free check that is skipped most often. A machine that starts and then does nothing at all can be waiting on a delay that was set by accident.
The order to work in
- First: Check where the drain hose enters the standpipe — It is first because both are about where the hose sits rather than what is in it.
- Second: Note the exact point in the programme where it stops — It comes second because a cycle that always stops at the same step is describing the step it cannot complete.
- Third: Open the adjacent cabinet and look at the hose run — It comes last because the whole hookup is reachable from the next cupboard without moving the machine at all.
Owner-side checks, step by step
- Check the drain hose is high enough and not pushed far into the standpipe — The hose should enter the standpipe rather than sit deep in it, and it should rise before it falls.
About 15 min
- Open the pump filter and check the drain hose for kinks — Put a towel and a tray down, open the filter slowly, clear it, then follow the hose to the standpipe looking for a kink or a crush.
Tools: shallow tray, towelAbout 25 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
Shut both taps and isolate the machine before a hose or a filter is opened. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water from a filter can be hot, so use a tray. The door lock is a safety device holding back a drum of water — never defeat it.
When to call a technician
The line is simple: everything above is reachable and reversible, and nothing below it is. 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 is deliberately not on this page
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.
