What you are actually seeing
- The machine restarts the same phase repeatedly
- The cycle ends but the dishes are cold and wet
- The cycle runs for hours and never ends
- The cycle stops part-way with water in the tub
- Not this fault: A long cycle on an eco programme
Ranked causes on a Conservator dishwasher
- Water not reaching temperature so the cycle will not advance — Ranked here because: the temperature control is a mechanical thermostat, which either makes contact or does not — it is a quick, decisive check
- Cycling thermostat or thermistor out of range — Ranked here because: there is very little electronics on this line, so a board is the last thing to accuse rather than the first
- Control or timer fault — Ranked here because: the temperature control is a mechanical thermostat, which either makes contact or does not — it is a quick, decisive check
- Drain step failing — 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
- Fill step not reaching level — Ranked here because: a restriction builds gradually, so performance falls off long before anything stops
- Overfill float tripping mid-cycle — Ranked here because: a machine that cannot fill correctly fails in ways that look like every other fault
What to check, and in what order
- Check the base pan for water with a paper towel
- Confirm the supply valve is fully open and the fill hose is not kinked behind the machine
- Run a cycle and note exactly where it stops, and whether there is water in the tub at that point
- Open the door mid-cycle and judge whether the water is hot
Steps you can safely do yourself
- Run a cycle and note exactly where it stops, and whether there is water in the tub at that point — Tools: none — Estimated time: one full cycle
- Open the door mid-cycle and judge whether the water is hot — Tools: none — Estimated time: a couple of minutes
- Clean the filter and confirm the machine drains fully when the cycle is cancelled — Tools: gloves, cloth — Estimated time: about twenty minutes
- Run the kitchen tap hot before starting, then compare the cycle length — Tools: none — Estimated time: one full cycle
- Check the base pan for water with a paper towel — Tools: paper towel — Estimated time: a few minutes
