Start here
When the DWT line refuses a programme, the latch is the first suspect and the control board is the last. These models put the display upstream of the latch switch, which is why a fully lit panel proves so much less than owners expect.
What owners actually see
- The machine starts if the door is pressed firmly while starting — For the models in the table on this page, conclusive for a latch fault, and it means the switch is marginal rather than the control being dead.
- Plumbing work was done recently under the sink — The service tap is almost always closed during that work and very often not reopened afterwards.
- The panel was wiped down shortly before the fault — Control locks arm with a long press, and a cloth held against a button does exactly that. That holds across every model this page covers.
- NEAR MISS: the machine runs but leaves water in the tub — That is a drainage fault and belongs on the drainage page for this family.
Ranked causes on this line
- The door is closed but not latched — First on the DWT line by a wide margin. A protruding handle, a tall item in the upper rack or a slightly sagging door stops the latch engaging, and the panel still lights because the display is upstream of the latch switch. It does not vary across the models listed on this page.
- No supply at the socket or a tripped breaker — Second because it is free to check and because a dishwasher shares its circuit with other kitchen loads often enough for an unrelated appliance to have tripped it. It is the same on all the models in the table on this page.
- A delay start left set from a previous cycle — These models keep a selected delay through a door open and close, so a machine that was set overnight and then reopened appears dead when it is simply counting down.
- No water at the supply tap — The machine checks for fill before it commits to a programme, so a closed or partly closed service tap stops the cycle at the very beginning with no error the owner can read.
- A failed thermal cut-out or wiring harness fault — Last because it is rare and because it needs continuity testing rather than observation. It usually follows an earlier fault such as a long overheat, so it is worth mentioning the history to a technician.
The diagnostic order
- Press the door firmly shut and listen for the latch — First because it is the most common cause on the DWT line and because the latch makes an audible click when it engages that a nearly-closed door does not. The same is true of each model covered here.
- Look for a protruding item in either rack — A handle through the upper basket or a tall board in the lower one holds the door a few millimetres proud, which is enough to stop the latch and invisible from the front.
- Check the socket with something else — Third, because it separates the appliance from the circuit in seconds and because a shared kitchen circuit is tripped by other loads more often than by the dishwasher. Every model in this family behaves this way.
Safety first
Safety
Power down at the breaker first. A circuit that trips every time the machine is started is reporting an electrical fault, and repeated resetting is not a diagnostic step.

Where the owner line is
Book a visit if the appliance trips the household circuit on any attempt to start, or if there is any smell of burning at the door edge or the base. The models in the table behave the same way here.
