What you are actually seeing
- A cycle that runs but ignores the selected programme
- A code or a flashing light pattern on the panel
- The panel is dead and no button does anything
- Not this fault: A dead panel with a tripped breaker
Ranked causes on a Conservator dishwasher
- Door not latching or the latch switch failed — Ranked here because: this platform is mechanical by design, so wear parts and couplings fail as parts rather than as symptoms of a board
- Touch panel or membrane worn through — Ranked here because: a simple machine gives the owner more ways to load and dose it wrong, and those show up as faults
- Marginal supply, tripped breaker or GFCI — 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
- Overfill float stuck or the tub has leaked into the base — Ranked here because: a machine that cannot fill correctly fails in ways that look like every other fault
- Control reporting a drainage or fill fault — Ranked here because: the pump is the only powered part in the drain path and it takes everything the machine washes off
- Control latched after a power event — Ranked here because: a supply fault imitates a component fault exactly and costs nothing to eliminate
What to check, and in what order
- Press every button on the panel in turn and note which respond
- Close the door firmly and listen for the latch to click, then check nothing in the racks crosses the door line
- Check the breaker and any GFCI outlet on the kitchen circuit
- Switch the machine off at the breaker for five minutes, restore it and try again
Steps you can safely do yourself
- Check the breaker and any GFCI outlet on the kitchen circuit — Tools: none — Estimated time: a few minutes
- Switch the machine off at the breaker for five minutes, restore it and try again — Tools: none — Estimated time: under ten minutes
- Look for standing water in the tub and check the filter and the drain — Tools: gloves — Estimated time: about a quarter of an hour
- Slide a sheet of paper under the machine and check for water in the base pan — Tools: paper towel — Estimated time: a few minutes
- Press every button on the panel in turn and note which respond — Tools: none — Estimated time: a few minutes

When to call a technician
a code names the heating circuit or the pump the machine trips a breaker or a GFCI when it runs the door latch assembly needs replacing rather than adjusting
