What you are actually seeing
- Everything wet at the end but otherwise clean
- Food redeposited on everything as a grey smear
- Baked-on residue that will not shift
- Grit and food particles left on the dishes
- Not this fault: Poor results with water left in the tub
Ranked causes on a Conservator dishwasher
- Spray arm jets clogged or arm not turning — Ranked here because: this platform is mechanical by design, so wear parts and couplings fail as parts rather than as symptoms of a board
- Wash water not hot enough — Ranked here because: the temperature control is a mechanical thermostat, which either makes contact or does not — it is a quick, decisive check
- Fill volume or water pressure low — Ranked here because: these machines are commonly installed by the owner or the delivering dealer, and levelling and venting errors are the most frequent finding
- Filter blocked or not seated — Ranked here because: a simple machine gives the owner more ways to load and dose it wrong, and those show up as faults
- Overloading, nesting or blocking the arms — Ranked here because: a simple machine gives the owner more ways to load and dose it wrong, and those show up as faults
- Detergent dose, type or dispenser fault — Ranked here because: dosing and product choice change the result more than any component on the machine
What to check, and in what order
- Run the kitchen tap hot before starting the cycle
- Check that the dispenser flap is not blocked by a tall item and that it opened during the cycle
- Fill the rinse-aid reservoir and, if fitted, the salt reservoir
- Remove the filter assembly, wash it under a running tap and refit it correctly
Steps you can safely do yourself
- Fill the rinse-aid reservoir and, if fitted, the salt reservoir — Tools: rinse aid, dishwasher salt — Estimated time: about ten minutes
- Remove the filter assembly, wash it under a running tap and refit it correctly — Tools: washing-up brush — Estimated time: about a quarter of an hour
- Take out both spray arms, hold them to the light and clear every blocked jet — Tools: toothpick or fine wire, warm water — Estimated time: about twenty minutes
- Load the machine as usual, then spin both arms by hand before starting — Tools: none — Estimated time: a couple of minutes

When to call a technician
the water is not being heated, since that is the element and its thermostat cleaning is poor everywhere with clean filters and clear jets, which points at the wash pump the machine is not filling to its normal level
