Start here
On this platform the filter and the spray arms account for most cleaning complaints, and both are reachable without a tool. The wash water on this platform is filtered and recirculated, so a filter left unattended puts the food back on the dishes. Every one of the first checks is owner work and needs nothing but hands.
What you actually see
- Cutlery comes out clean and plates do not — The basket sits in the middle of the spray pattern and the racks do not. It points at reach rather than at chemistry.
- The problem appeared after a change of detergent — Worth eliminating first. Tablets, powder and gel behave differently in soft water and at low temperatures.
- Gritty deposits left on everything in the machine — Debris is being recirculated rather than removed, which points straight at the filter assembly.
- A white film on glassware that wipes off — Hard water and rinse aid rather than a fault. It is a water chemistry story, not a mechanical one.
- NEAR MISS — there is standing water in the bottom — That is a drainage fault and it has its own page for this family. It also produces dirty dishes, from the other direction.
What it turns out to be, in order
- Filter assembly blocked — First on this roster by a wide margin. The machine filters its own wash water and returns it to the spray arms, so a filter full of last week's debris puts that debris back onto the dishes with pressure behind it.
- Spray arm jets blocked, or an arm that cannot turn — Second. Scale closes jets from the inside where you cannot see it, and one tall item hanging through a rack will stop an arm for an entire cycle.
- Loading faults — overlap, shadowing, blocked arms — Not a failure at all, and responsible for more complaints than any component on the list. Items nested together present one surface to the water and hide the other.
- Water arriving too cool, or the heater not working — Detergent needs heat to dissolve and fat needs heat to move. A machine filling with cool water and failing to raise it does everything else correctly and still leaves a film.
- Detergent stale, wrong or in the wrong compartment — Powder loses its ability to work long before it looks any different, and a dispenser flap blocked by a tall item never opens at all.
- Circulation pump or diverter fault — Bottom of the list. A pump that cannot build pressure produces a consistent dead zone, and that is where owner diagnosis ends.
The diagnostic order for this family
- Take out the filter assembly and look at it — If it is loaded, that is the answer and the rest of the page is academic. Rinse it under a tap and run the machine empty.
- Spin both spray arms by hand — They should turn freely through a full revolution without touching anything in either rack.
- Open the door mid-cycle and feel the water — Genuinely hot means the heating side is working. Lukewarm explains undissolved detergent and greasy dishes at once.
What to do before the panel comes off
Safety
Kill the supply before anything else happens: unplug it, or switch the breaker off. A capacitor can hold a charge long after the power has gone.

When this stops being owner work
Clean the filter and reload before calling anyone — a large share of cleaning complaints end there. Call when the same dead zone survives a clean filter, clear jets and a half-empty machine, because at that point the fault is in the water delivery and not in what the owner can reach.
