Start here
On this platform the filter and the spray arms account for most cleaning complaints, and both are reachable without a tool. Blocked jets, an arm that cannot turn because a handle is hanging through the rack, and a filter nobody has cleaned cover most of it. Work the list in order and the expensive suspicion usually never comes up.
How it presents
- 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.
- Dishes are wet as well as dirty — Two symptoms with one cause where the machine is not reaching temperature at all.
- Gritty deposits left on everything in the machine — Debris is being recirculated rather than removed, which points straight at the filter assembly.
- The top rack is dirty and the bottom rack is clean — The upper arm is not getting water or not turning. A shadow on one rack is an arm problem, not a detergent problem.
- 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 — Top of the list by a wide margin. The machine returns its own wash water to the spray arms through this filter, so a full one delivers last week's debris back onto clean plates under pressure.
- 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 that fills cool and cannot raise it does everything else correctly and still leaves a film.
- Circulation pump or diverter fault — Last on the list. A pump that cannot build pressure, or a diverter stuck feeding one arm, produces a consistent dead zone and 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.
- 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.
- Run an empty cycle with the racks out — Separates a machine fault from a loading fault definitively, which is worth knowing before anything is ordered.
- Feel the door and the outer panel partway through the main wash — A machine that never warms is a heating fault wearing a cleaning fault's clothes.
Safety before diagnosis
Safety
Nothing below happens with the machine live. Unplug it or switch off its breaker, and treat any capacitor as charged until it has been discharged properly.

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.
