The short answer
A Cove dishwasher that stalls or runs far longer than its stated time is usually waiting for water or for temperature rather than failing. On a quiet machine you cannot hear it waiting, so a cycle that has simply extended reads as a stall. Check the supply and the hot water before looking inside the machine.
What you are actually seeing
- The cycle stops partway with water still in the tub — Means: on-page
- The cycle runs far longer than its stated time — Means: on-page
- The machine pauses at the same point every time — Means: on-page
- The cycle indicator stops changing — Means: on-page
- The machine restarts its cycle from the beginning — Means: on-page
- The machine never begins a cycle at all — Means: different-fault — Go to: cove-dishwasher-wont-start
- The cycle completes but the tub still holds water — Means: different-fault — Go to: cove-dishwasher-drainage-failure
- Body: Match what you see before you take anything apart. The cycle stops partway with water still in the tub. The cycle runs far longer than its stated time. The machine pauses at the same point every time. The cycle indicator stops changing. The machine restarts its cycle from the beginning. Some near-miss symptoms belong on a different page: The machine never begins a cycle at all points at a start or interlock fault, covered on cove-dishwasher-wont-start; The cycle completes but the tub still holds water points at a drain fault, covered on cove-dishwasher-drainage-failure.
Causes, ranked for this machine
- A restricted or closed supply valve, so the machine waits for a fill it never completes — Why this rank: First because a machine waiting for water looks exactly like a stalled machine, and the valve in the adjacent cabinet is disturbed by other kitchen work
- A cool hot supply, so the control extends the heating step — Why this rank: This produces a cycle that runs for hours with no error at all, and on a quiet machine it is invisible until the end
- A restricted drain, so a drain step cannot complete — Why this rank: Directly linked to the filtration and the drain path, and free to check
- The door being opened mid-cycle and not properly re-latched — Why this rank: The machine holds where it was and looks stalled, which owners rarely connect to the interruption
- A failed sensor, valve or control board — Why this rank: Last because it needs a part and everything above it is free to rule out
- Body: Ranked for a premium built-in dishwasher: hard-plumbed, on a dedicated supply, installed under a worktop by a fitter, quiet by design, with hand-cleaned filtration and a condensation dry that depends on rinse aid. Most likely: A restricted or closed supply valve, so the machine waits for a fill it never completes. First because a machine waiting for water looks exactly like a stalled machine, and the valve in the adjacent cabinet is disturbed by other kitchen work. Next most likely: A cool hot supply, so the control extends the heating step. This produces a cycle that runs for hours with no error at all, and on a quiet machine it is invisible until the end. Third: A restricted drain, so a drain step cannot complete. Directly linked to the filtration and the drain path, and free to check. Fourth: The door being opened mid-cycle and not properly re-latched. The machine holds where it was and looks stalled, which owners rarely connect to the interruption. Fifth: A failed sensor, valve or control board. Last because it needs a part and everything above it is free to rule out.
What to check, in order
- Check the supply valve in the adjacent cabinet is fully open
- Run the kitchen hot tap until hot, then restart the cycle
- Clean the filtration and confirm the machine drains fully
- Note the exact point in the cycle at which it stalls
- Body: Each check rules out the causes above it. First, check the supply valve in the adjacent cabinet is fully open. Second, run the kitchen hot tap until hot, then restart the cycle. Third, clean the filtration and confirm the machine drains fully. Fourth, note the exact point in the cycle at which it stalls.
Checks you can safely make yourself
- Open the adjacent cabinet and confirm the supply valve is fully open rather than part turned — Tools: torch — Time estimate: a quarter of an hour
- Run the kitchen hot tap until hot, start a normal cycle immediately and watch whether it progresses — Tools: none — Time estimate: one cycle
- Switch off at the breaker, clean the whole filter assembly, restore power and run a short cycle to confirm it drains — Tools: brush, gloves — Time estimate: half an hour
- Start a cycle and write down the elapsed time and the indicator state when it stalls — Tools: notepad — Time estimate: one cycle
- Switch off at the breaker, restore power, close the door firmly and run a short cycle through without opening it — Tools: none — Time estimate: one short cycle
- Body: Checks an owner can make with the machine switched off at the breaker, or by watching a cycle. Step one: Open the adjacent cabinet and confirm the supply valve is fully open rather than part turned. Tools: torch. Time: a quarter of an hour. Step two: Run the kitchen hot tap until hot, start a normal cycle immediately and watch whether it progresses. Tools: none. Time: one cycle. Step three: Switch off at the breaker, clean the whole filter assembly, restore power and run a short cycle to confirm it drains. Tools: brush, gloves. Time: half an hour. Step four: Start a cycle and write down the elapsed time and the indicator state when it stalls. Tools: notepad. Time: one cycle. Step five: Switch off at the breaker, restore power, close the door firmly and run a short cycle through without opening it. Tools: none. Time: one short cycle.
Safety first
Safety
Switch off at the breaker before removing filtration or reaching into the sump, and do not open the door on a stalled machine full of hot water. Unplug the appliance or switch off its breaker before removing any panel. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. unplug-before-service
Where the owner fix ends
Call a technician when the supply valve is fully open, the hot tap runs hot, the filtration is clean and the machine drains, and the cycle still stalls at the same point. The fill valve, the level sensor and the control all sit behind panels that require the machine to be drawn out.
