The answer first
The Beko DDN 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 problem list for this family
- 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 DDN Dishwasher: Will Not Drain.
- Dishes come out gritty, filmed or still soiled — Read the pattern before the cause: part of the load dirty is a flow problem, the whole load filmed is a chemistry one. See Beko DDN 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 DDN 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 DDN Dishwasher: Will Not Start.
Frequency order for this family
- 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 — 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.

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
Power the appliance down at the breaker first and mop any standing water before you kneel beside it. A wet floor under a built-in cabinet is the likeliest injury in this whole job.
When to stop and call
The owner boundary on this family is the kick panel. Filters, spray arms, the door gasket, the loading and the household waste connection are all reachable without tools; the pumps, the heater and the control are not.
