The answer first
The Beko DDT family covers a set of built-in dishwashers with the same core layout: a single pump feeding both spray arms through a hand-removable filter stack, and a single drain route into household waste. That layout determines the problems this page routes you to.
The faults, and where each is covered
- The tub still holds water when the programme ends — The single most reported fault on this line, and the filter stack over the pump inlet is behind most of it. See Beko DDT Dishwasher: Will Not Drain.
- Plates coming out with grit, film or dried-on soil — Flow rather than heat in most cases, since both arms are fed through the same filter. See Beko DDT Dishwasher: Does Not Clean or Dry.
- Water reaching the floor during or after a cycle — The base tray carries any internal escape forward, so the puddle proves that water escaped and not where from. See Beko DDT Dishwasher: Water Leak.
- The panel lights but no cycle begins — Almost always the door latch, a control lock or a delay setting rather than a failed board. See Beko DDT Dishwasher: Will Not Start.
The problem classes, most reported first
- Drainage faults — The largest share of reports on this family. The filter stack sits directly over the pump inlet, so one handful of debris restricts filtration and drainage at the same moment.
- Cleaning and drying complaints — Second, and closely related to the first: both spray arms draw through the same stack, so a partial restriction degrades the wash weeks before it stops the drain.
- Leaks at the door or the base — Then leaks, where the door gasket leads. It is one moulded strip, so a hardened corner breaks the seal along the whole edge rather than at a point.
- No-start conditions — Fourth and usually not a fault at all: a latch that has not engaged, a control lock, a delay setting or a closed supply tap account for most of them.

Problem classes on this family, ranked
General guidance| Problem class | Reported share | Usual cause |
|---|---|---|
| Drainage failure | Highest | Filter stack and drain hose |
| Cleaning performance | Second | Filter stack, spray arms, loading |
| Water leak | Third | Door gasket and detergent foaming |
| Will not start | Lowest of the four | Door latch, locks and delay settings |
Based on: No counted sample stands behind this ranking: it orders the problem classes against each other from technician experience on this line, and is not a share of any corpus.

Safety
Isolate the machine at the breaker before anything is dismantled, and close the supply tap before touching the fill connection. Wear gloves for the filter stack.
When to stop and call
Everything reachable from inside the tub or through the kick panel is owner work on the Beko DDT line, and anything that needs the machine out of its housing is not. Call immediately if the appliance trips its breaker or if water has reached a socket.
