Read this first
When the DDS line will not begin a cycle, separate three states first: nothing lights at all, the panel lights but nothing happens, or the cycle starts and immediately stops. Each points at a different part of the chain, and on this platform the middle case is the most common and the cheapest to resolve.
The observations that matter
- The door feels different when it closes — On each of the models covered here, a latch beginning to wear changes the closing action before it stops working, and the change is felt rather than seen.
- The machine starts if the door is pressed firmly while starting — 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. It is the same on all the models in the table on this page.
- NEAR MISS: the machine runs but the load stays dirty — That is a cleaning fault, and the cleaning-performance page for this family covers it.
The causes in likelihood order
- The door is closed but not latched — First on the DDS 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. The same is true of each model covered here.
- 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. This applies to the whole line rather than to one model.
- Child lock or control lock armed — A lock arms with a long press and is easily set by accident during cleaning. The panel then acknowledges a press and refuses the cycle, which reads exactly like a failed start button.
- A latch switch that has become marginal — Between working and failed there is a stage where the switch makes contact only when the door is pressed, which produces an intermittent no-start that owners find maddening.
- 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 order to work in
- Press the door firmly shut and listen for the latch — First because it is the most common cause on the DDS line and because the latch makes an audible click when it engages that a nearly-closed door does not. Every model in this family behaves this way.
- 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. That holds across every model this page covers.
- Read the panel legend for the lock symbol — Every build marks the lock button, and the legend tells you the press duration that clears it without guesswork.
Before you open anything
Safety
Isolate the machine at the breaker before any panel is removed; stored charge can remain after the supply is cut. Do not operate the latch mechanism with a tool while the appliance is powered, and never wedge, prop or hold the door closed to make a cycle run.

The service boundary
The line here is the door panel: everything in front of it is an owner check and everything inside it is service work. Call immediately if the appliance trips the household circuit, because that is an electrical fault rather than a start fault. That is true of every model this family spans.
