The short answer
Control complaints on a Cove dishwasher are usually a lock, a supply interruption or the machine correctly reporting a water problem rather than a failed board. On an integrated machine the control lives along the top edge of the door where it is operated without being seen, which makes an accidental lock unusually easy to set.
What you are actually seeing
- The control shows nothing although the machine has power — Means: on-page
- An indicator repeats a pattern rather than a cycle state — Means: on-page
- Buttons respond but the selected programme does not start — Means: on-page
- A code appears at the same point in every cycle — Means: on-page
- The control behaves differently after a kitchen power interruption — Means: on-page
- Nothing at all happens and the control is dead — Means: different-fault — Go to: cove-dishwasher-wont-start
- The control is normal and the cycle stalls — Means: different-fault — Go to: cove-dishwasher-cycle-fault
- Body: Match what you see before you take anything apart. The control shows nothing although the machine has power. An indicator repeats a pattern rather than a cycle state. Buttons respond but the selected programme does not start. A code appears at the same point in every cycle. The control behaves differently after a kitchen power interruption. Some near-miss symptoms belong on a different page: Nothing at all happens and the control is dead points at a supply failure, covered on cove-dishwasher-wont-start; The control is normal and the cycle stalls points at a cycle fault, covered on cove-dishwasher-cycle-fault.
Causes, ranked for this machine
- A control lock or child lock set on a top-edge control — Why this rank: First because it is free to clear and because a control you operate without seeing it is unusually easy to set by accident
- A supply interruption leaving the control in an odd state — Why this rank: Explains a control that misbehaved from the moment of a power cut in the kitchen
- A door interlock that is not making cleanly, often through panel fouling — Why this rank: The control cannot proceed without it, and a marginal latch produces confusing intermittent behaviour
- A genuine fault the control is correctly reporting, such as a fill or drain problem — Why this rank: Treating the code as the fault sends owners after the wrong part
- A failed control panel or board — Why this rank: Last because it needs a part and everything above it is free
- 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 control lock or child lock set on a top-edge control. First because it is free to clear and because a control you operate without seeing it is unusually easy to set by accident. Next most likely: A supply interruption leaving the control in an odd state. Explains a control that misbehaved from the moment of a power cut in the kitchen. Third: A door interlock that is not making cleanly, often through panel fouling. The control cannot proceed without it, and a marginal latch produces confusing intermittent behaviour. Fourth: A genuine fault the control is correctly reporting, such as a fill or drain problem. Treating the code as the fault sends owners after the wrong part. Fifth: A failed control panel or board. Last because it needs a part and everything above it is free.
What to check, in order
- Switch off at the breaker and restore power, then read the control again
- Read the whole top edge for a lock symbol and clear it
- Close the door firmly and watch whether the behaviour changes
- Write down the exact code or indicator pattern and when it appears
- Body: Each check rules out the causes above it. First, switch off at the breaker and restore power, then read the control again. Second, read the whole top edge for a lock symbol and clear it. Third, close the door firmly and watch whether the behaviour changes. Fourth, write down the exact code or indicator pattern and when it appears.
Checks you can safely make yourself
- Switch off at the breaker, wait long enough for the control to clear, restore power and read the control — Tools: none — Time estimate: half an hour
- Read the whole top edge of the door with a torch for a lock or key symbol and clear it following the markings — Tools: torch — Time estimate: a quarter of an hour
- Close the door firmly, select a short cycle and watch whether the control responds normally — Tools: none — Time estimate: a few minutes
- Write down the exact code or the indicator pattern and the point in the cycle when it appears — Tools: notepad — Time estimate: one cycle
- Check whether the custom panel is fouling the cabinetry and preventing a clean latch — Tools: torch — Time estimate: a quarter of an hour
- Body: Checks an owner can make with the machine switched off at the breaker, or by watching a cycle. Step one: Switch off at the breaker, wait long enough for the control to clear, restore power and read the control. Tools: none. Time: half an hour. Step two: Read the whole top edge of the door with a torch for a lock or key symbol and clear it following the markings. Tools: torch. Time: a quarter of an hour. Step three: Close the door firmly, select a short cycle and watch whether the control responds normally. Tools: none. Time: a few minutes. Step four: Write down the exact code or the indicator pattern and the point in the cycle when it appears. Tools: notepad. Time: one cycle. Step five: Check whether the custom panel is fouling the cabinetry and preventing a clean latch. Tools: torch. Time: a quarter of an hour.
Safety first
Safety
Switch off at the breaker before removing any panel or disturbing the door console. A capacitor can hold a charge after the power is off, and on an integrated machine the console sits behind the custom 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 machine has been fully powered down, no lock is set, the door latches cleanly and a code still repeats. Give them the exact pattern and the point in the cycle, because that is what identifies the circuit involved.

Fully integrated machines carrying a custom cabinet panel and machines with a finished front share the ranking above but not every part, and this page does not cover a specific model, control revision or installation.
