The short answer
The DW line is a Bertazzoni dishwasher line covering the models in the table below. The service record on these machines is dominated by the filter stack: it explains both the poor-cleaning complaints and most of the drainage ones.
The problem classes on these models
- Will not start — A dark panel is usually the switched spur; a lit panel that refuses to run is the door latch. For the whole of it, read “Bertazzoni DW Dishwasher: Will Not Start” — the link is below.
- Will not drain — Standing water covering the filter plate at the end of a cycle, often with dirty water redeposited on the load. For the whole of it, read “Bertazzoni DW Dishwasher: Will Not Drain” — the link is below.
- Not cleaning properly — Dishes coming out dirty is nearly always the filter stack or the spray-arm jets on this line. It is covered in full on “Bertazzoni DW Dishwasher: Not Cleaning Properly”, linked below.
- Leaking water — Water at the door face during the wash is the gasket or foam; water under the cabinet is a hose or a fitting. For the whole of it, read “Bertazzoni DW Dishwasher: Leaking Water” — the link is below.
- Poor drying — Wet plastics are normal; wet china is not. No separate page covers it in this set, so the first move is simple: top up the rinse aid and check whether the tub gets warm.
- Film, spotting and hard water — Scale and spotting are a chemistry problem; no repair will fix them. It has no page of its own on this line; the opening move is to fill the salt and rinse-aid reservoirs and set the water hardness.
Causes, most likely first
- Leaking water — First — and it is not close. Water at the door face during the wash is the gasket or foam; water under the cabinet is a hose or a fitting.
- Will not drain — Second on this list. A sump that will not empty. The filter sits directly over the pump inlet, so one blockage stops both.
- Not cleaning properly — Third most likely. Grit redeposited on the load, or a clean bottom rack with a dirty top one. Both are flow problems rather than detergent problems.
- Film, spotting and hard water — Less common than the three above. White film on glassware is water chemistry rather than a fault, and it is cured with salt and rinse aid.

When to call a technician
Everything reachable with the door open, plus the plumbing behind the machine, is yours on these dishwashers. Call when the tub never gets warm, when the pump is silent at the drain step, or when water reaches the kitchen units.
