This page profiles the Beko DUT dishwasher family: the models the line spans, what they have in common, and the problems that actually occur on them. Drainage and cleaning faults are the two that dominate, and they share a cause often enough that they are usually diagnosed together.
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 DUT 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 DUT Dishwasher: Does Not Clean or Dry.
- Water on the floor at the front foot or behind the cabinet — Usually the door gasket or over-foaming detergent, with the base tray carrying water forward and disguising where it came from. See Beko DUT 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 DUT Dishwasher: Will Not Start.
The problem classes, most reported first
- Drainage faults — Reported more than any other fault on this line, and for a structural reason: the filter stack sits directly over the pump inlet, so one obstruction stops filtration and drainage together.
- Cleaning and drying complaints — Next, and usually the same blockage at an earlier stage. Both spray arms draw through that stack, so the wash degrades weeks before the drain ever fails.
- Leaks at the door or the base — Third. The door gasket is a single moulded strip, so a hardened or lifted section 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.

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 first
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.
Where the owner line is
Everything reachable from inside the tub or through the kick panel is owner work on the Beko DUT 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.
