The short answer
Three things account for nearly every will-not-start call on this platform, and none of them is the control board. The door latch has to make fully before anything happens, there is usually an isolator switch hidden in the cupboard under the sink, and the anti-flood float in the base pan stops the machine dead once water reaches it. Check all three before considering anything electronic.
What you are seeing
- The panel accepts a program and then nothing happens at all — Note: The door latch has not fully engaged. Close the door slowly and listen for the second click.
- The panel is completely dark with no lights — Note: No supply. Look for the isolator switch in the cupboard under the sink before anything else.
- The drain pump runs immediately and the machine never fills — Note: Flood protection has latched on water in the base pan.
- It starts, runs briefly and stops with the lights still on — Note: It is waiting for a condition it cannot reach, most often a fill or a drain.
- It worked until a power cut and has not since — Note: A latched program that needs a cancel and drain sequence to clear.
- Nothing happens and the breaker has tripped — Note: An electrical fault. Leave it isolated and read the electrical safety page.
Ranked causes on this brand
- Door latch not fully engaged — Why this rank: First because it produces the exact and unmistakable behaviour of a program accepted and then abandoned, and because the latch carries the weight of every close for the life of the machine.
- Isolator switch under the sink switched off — Why this rank: Second because these machines are almost always wired through a switched isolator hidden in the sink cupboard, and it gets knocked off by anything stored in there.
- Flood protection latched on water in the base pan — Why this rank: Third: it produces a machine that is clearly alive and clearly refusing to work, which is why owners so often conclude the board has failed.
- A program latched by a power interruption — Why this rank: Fourth because it is easy to clear once you know it exists, and impossible to diagnose if you do not.
- Water inlet not opening at the anti-flood hose head — Why this rank: Fifth: the machine is silent and waiting rather than dead, which distinguishes it from every cause above.
- Door latch microswitch or control board failure — Why this rank: Last, because they are genuine failures but far less common than the five conditions above them, and because a board on a discontinued badge is the hardest part in the machine to source.
What to check, in order
- Look at the panel and note whether any light comes on at all — Why: A dark panel is a supply problem; a lit panel is not, and this splits the page in two.
- Open the cupboard under the sink and find the isolator switch — Why: It is the most commonly overlooked cause on a built-in machine and it costs nothing to check.
- Close the door slowly and listen for the latch to make its second click — Why: A door that appears shut but has not latched will accept a program and abandon it.
- Start a program and listen for the drain pump running continuously with a dry tub — Why: That sound is flood protection and it points at the base pan rather than at anything electrical.
- Switch off at the isolator for several minutes and back on, then try the shortest program — Why: This clears a latched program without clearing anything that matters.
Checks you can do safely
- Open the door and press a button. Note whether any light or indicator responds at all before doing anything else. — Tools: none — Time: one minute
- Open the cupboard under the sink, find the isolator switch and confirm it is on. Check the breaker as well. — Tools: torch — Time: five minutes
- Close the door slowly and deliberately, listening for the latch to make its second click, then select the shortest program. — Tools: none — Time: five minutes
- Switch off at the isolator, wait several minutes, switch back on, and try a program again to clear anything latched from a power interruption. — Tools: none — Time: ten minutes
- Confirm the tap under the sink is fully open and the inlet hose is not kinked where the machine was pushed back. — Tools: torch — Time: ten minutes
- Switch off, remove the kick panel and inspect the base pan for water. Dry it completely and leave the machine off with the door ajar overnight. — Tools: screwdriver, torch, cloths — Time: half an hour plus overnight
Before you open anything
Safety
Switch off at the isolator and at the breaker before removing the kick panel or drying the base pan, where the flood float, its microswitch and machine wiring all sit together. Never tape, prop or otherwise defeat the door latch to make the machine run with the door open: the latch is what stops a tub of near-boiling water being opened mid-cycle. If a breaker has tripped, leave the machine isolated rather than resetting it repeatedly. Never cut or repair the inlet hose, which carries mains wiring in its outer sleeve to a solenoid at the tap end. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. — Id: unplug-before-service
Where the service line falls
The panel is lit, the isolator is on, the door latches with a clear second click, the base pan is dry, and the machine still does nothing. The panel is completely dark with the isolator on and the breaker holding, which means the supply is reaching the cupboard but not the machine. The base pan refills after drying, because the leak has to be found before the machine should run again. The machine waits silently at fill with a fully open tap and an unkinked hose, which points at the solenoid in the anti-flood hose head. The machine will run with the door open, which is a latch safety fault and means stopping use immediately.

What this page does not cover
This page is generalized across families and models on this European built-in platform. It prints no fault codes, because the indication scheme differs by generation and no code table for this brand exists in this reference. It does not cover a specific model family, nor freestanding variants wired to a plug and socket rather than through a fixed isolator. Identify your machine from the rating plate on the edge of the door or inside the tub rim rather than from the badge, because this manufacturer supplied the same platform under several group badges and a parts desk cross-references by platform, not by name.
