What is actually happening
A WGA washer that starts a cycle and then stops is usually waiting for a condition it cannot reach - enough water, a locked door, a drained tub or a temperature - rather than suffering a broken part. The machine is not stuck; it is stalled at a step, and finding the step is the diagnosis.
The observable tells
- The programme time stops counting down and stays put — The machine is waiting at a step. Where the timer froze is the most useful single clue you have.
- The cycle finishes but the drum is still full of water — A drain gate that was never satisfied, which is why the door stays locked afterwards.
- NEAR MISS - the cycle takes much longer than the label says — Programme times are nominal and adapt to conditions. A long cycle is not a stalled cycle.
- The display shows a fault and the machine stops immediately — The control has detected the failed condition itself; read what the machine says before overriding it.
- The time remaining goes up instead of down — Normal adaptive behaviour when the fill is slow or the load is unbalanced, not a fault on its own.
Ranked causes for these models
- Restricted fill: taps part-closed or inlet filters blocked — First on this family because the machine will not proceed until it has its water, and a partly open tap produces exactly this stall.
- Pressure or level sensing reading wrong — The machine acts on a level that is not true, so it either never fills enough or believes it is already full.
- Drain blocked at the filter or the hose — Second, and the reason so many stalled cycles end with a full drum and a locked door: no drain, no progress, no release.
- Control board or wiring fault — Last, because every cause above produces the same stall for far less money, and because a board is diagnosed by elimination rather than by inspection.
The order the layout dictates
- Check the drain hose height and that it is not pushed deep into the standpipe — An installation fault rather than a component fault, and one that produces an intermittent stall that looks electrical.
- Run the shortest programme available with an empty drum — Removes the load and the heating variables at once and shows whether the basic sequence can complete at all.
- Watch the fill rate with the drum empty — A fill that trickles is a restriction upstream, and seeing it removes the guesswork about whether the water is arriving.
- Open the drain filter and clear it — Do this early whenever the drum is holding water: it is both the test and the repair for the second-ranked cause.
Safety first
Safety
Switch the breaker off before a panel comes off. Mains, water and a heavy rotating drum share a small cabinet here, and the order of operations - power, water, then panel - is what keeps them apart.

Where the owner fix ends
Stop and call if the machine has already been part-dismantled and will not go back to a known state. A half-assembled drum machine is the one situation where a service call actually gets cheaper by being made earlier.
