The short answer
A Cove dishwasher that appears dead is usually running silently, waiting for its door latch, or off at a dedicated breaker rather than broken. On an integrated machine the controls are hidden along the top edge of the door and the machine is quiet by design, so the first job is to establish whether it is actually running.
What you are actually seeing
- No indicator and no sound at all after pressing start — Means: on-page
- The cycle indicator shows nothing with the door closed — Means: on-page
- The door will not latch fully against the custom panel — Means: on-page
- The machine beeps once and stops — Means: on-page
- Nothing has worked since a power interruption in the kitchen — Means: on-page
- The cycle starts and then stops partway — Means: different-fault — Go to: cove-dishwasher-cycle-fault
- A dedicated breaker trips when the machine starts — Means: different-fault — Go to: cove-dishwasher-electrical-safety
- Body: Match what you see before you take anything apart. No indicator and no sound at all after pressing start. The cycle indicator shows nothing with the door closed. The door will not latch fully against the custom panel. The machine beeps once and stops. Nothing has worked since a power interruption in the kitchen. Some near-miss symptoms belong on a different page: The cycle starts and then stops partway points at a cycle-progression fault, covered on cove-dishwasher-cycle-fault; A dedicated breaker trips when the machine starts points at an electrical fault to stop using the machine over, covered on cove-dishwasher-electrical-safety.
Causes, ranked for this machine
- The dedicated breaker or the isolating switch for the machine is off — Why this rank: First because a hard-plumbed machine on a dedicated supply is fed from a switch or a breaker the owner rarely sees, and it is routinely switched off during other kitchen work
- The door is not latching, often because the custom panel is fouling the cabinetry — Why this rank: On an integrated machine the panel has to clear the surrounding cabinets, and a panel that has swollen, shifted or been refitted stops the latch making
- The machine is actually running and the owner cannot tell, because it is quiet by design — Why this rank: Worth ruling out early, since a silent machine with a hidden control is easily assumed to be dead
- A control lock or delay start left set on a hidden top-edge control — Why this rank: Easy to set by accident on a control you operate without seeing it
- A failed door latch switch 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: The dedicated breaker or the isolating switch for the machine is off. First because a hard-plumbed machine on a dedicated supply is fed from a switch or a breaker the owner rarely sees, and it is routinely switched off during other kitchen work. Next most likely: The door is not latching, often because the custom panel is fouling the cabinetry. On an integrated machine the panel has to clear the surrounding cabinets, and a panel that has swollen, shifted or been refitted stops the latch making. Third: The machine is actually running and the owner cannot tell, because it is quiet by design. Worth ruling out early, since a silent machine with a hidden control is easily assumed to be dead. Fourth: A control lock or delay start left set on a hidden top-edge control. Easy to set by accident on a control you operate without seeing it. Fifth: A failed door latch switch or control board. Last because it needs a part and everything above it is free to rule out.
What to check, in order
- Find the isolating switch or breaker for the machine and confirm it is on
- Open the door and check the panel is not fouling the adjacent cabinetry
- Look for a cycle indicator or listen at the door before assuming the machine is dead
- Read the top-edge control for a lock or delay indicator
- Body: Each check rules out the causes above it. First, find the isolating switch or breaker for the machine and confirm it is on. Second, open the door and check the panel is not fouling the adjacent cabinetry. Third, look for a cycle indicator or listen at the door before assuming the machine is dead. Fourth, read the top-edge control for a lock or delay indicator.
Checks you can safely make yourself
- Find the isolating switch or the dedicated breaker serving the machine and confirm it is on, switching it off and on once — Tools: torch — Time estimate: a quarter of an hour
- Open and close the door slowly, watching whether the custom panel clears the adjacent cabinetry and the worktop edge — Tools: torch — Time estimate: a quarter of an hour
- Press start, close the door and put your ear to it, or look for a cycle indicator, before concluding the machine is dead — Tools: none — Time estimate: a few minutes
- Read the whole top edge of the door for a lock or delay symbol and clear it following the markings — Tools: torch — Time estimate: a quarter of an hour
- Switch off at the breaker, leave it long enough for the control to clear, restore power and try a short cycle — Tools: none — Time estimate: half an hour
- Body: Checks an owner can make with the machine switched off at the breaker, or by watching a cycle. Step one: Find the isolating switch or the dedicated breaker serving the machine and confirm it is on, switching it off and on once. Tools: torch. Time: a quarter of an hour. Step two: Open and close the door slowly, watching whether the custom panel clears the adjacent cabinetry and the worktop edge. Tools: torch. Time: a quarter of an hour. Step three: Press start, close the door and put your ear to it, or look for a cycle indicator, before concluding the machine is dead. Tools: none. Time: a few minutes. Step four: Read the whole top edge of the door for a lock or delay symbol and clear it following the markings. Tools: torch. Time: a quarter of an hour. Step five: Switch off at the breaker, leave it long enough for the control to clear, restore power and try a short cycle. Tools: none. Time: half an hour.
Safety first
Safety
Switch off at the isolating switch or the breaker before reaching behind the machine or into the cabinetry, and never tape or bypass the door latch. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.

Where the owner fix ends
Call a technician when the supply is proven on, the panel clears the cabinetry, the door latches, no lock is set and the machine is still dead. On an integrated machine the latch and the control sit behind a door skin and a custom panel, and disturbing that assembly is service work rather than owner work.
