The answer before the explanation
Cycle faults on the WGG line split cleanly by where the machine stops. This page works through the gates in the order the machine itself does, because diagnosing them out of order means testing components the cycle never reached.
The observable tells
- 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 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 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
- 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.
- 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.
- 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.
- 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.
Check in this order, and why
- 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.
- 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.
- 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.
- 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.
What to do before you start
Safety
Pull the plug before you open anything, and leave the door lock alone. It holds the door shut while the drum is turning and while there is water in the tub; it is not the component to defeat to make a test easier.

When to stop and book a visit
Call once the owner-side checks are clean, or the moment the fault points at the bearings, the motor or the control board. Those need the machine stripped or a meter on a live circuit, and neither is a kitchen job.
