The short version
On the DIN line the useful first question is not what has broken but which of three silences you have: a dark panel, a lit panel that refuses, or a cycle that begins and aborts. Each points at a different part of the machine and each is answered in under a minute.
What you will notice
- The machine beeps when the start button is pressed but does nothing — On the models this family spans, an acknowledged press with no action is the control refusing the cycle, which is a lock or precondition state and not a failed button.
- A delay indicator is lit — The programme has been accepted and deferred, so the machine is behaving correctly and will start later than expected.
- Only some buttons respond — A partially responsive panel is usually a child lock rather than a failed touch surface, and the lock is cleared with a button combination. The same is true of each model covered here.
- 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.
What is usually behind it
- The door is closed but not latched — First on the DIN 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 models in the table behave the same way 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. Every model in this family behaves this way.
- 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 service tap closed during unrelated work — The machine checks for fill before committing to a programme, so a closed tap produces a total and completely silent refusal with no error an owner can read.
- A failed supply component inside the door panel — Last because it cannot be confirmed without stripping the door and because everything upstream of it is free to check. It is suspected only when the socket is proven and the panel stays dark.
How to narrow it down
- Press the door firmly shut and listen for the latch — First because it is the most common cause on the DIN line and because the latch makes an audible click when it engages that a nearly-closed door does not. That is true of every model this family spans.
- 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. It does not vary across the models listed on this page.
- Power the machine down for a few minutes and retry — A control that has latched into an error state clears on a full power cycle, which distinguishes a transient fault from a failed component.
- Press the door firmly while pressing start — If the cycle begins, the latch switch is marginal and the diagnosis is complete without any tool at all.
Working safely
Safety
Switch off at the breaker before any panel is removed. A capacitor can hold a charge after the power is off. Leave the latch assembly and its wiring exactly as built, because that circuit is how the machine knows the door is shut.

When to book a visit
Call when the latch engages audibly, the socket is proven live, no lock or delay is set, the tap is open and the machine is still silent. Everything left is inside the door panel. It is the same on all the models in the table on this page.
