The short answer
A dishwasher that will not start is usually stopped by the door latch, the water supply or a delay state rather than by a failed control. The latch is a switch as well as a catch, and until it reports closed the machine is not permitted to do anything at all. Check the door, the supply and the settings before suspecting anything inside the cabinet.
What you are seeing
- No lights and no sound at all — Means: no supply, or the door circuit is open.
- The panel lights but the cycle never begins — Means: the machine has power and is waiting on a condition.
- It hums and then stops — Means: a fill or drain condition failing immediately.
- It starts only when the door is pressed hard — Means: the latch is making intermittently.
- A delay indication that was not selected deliberately — Means: a delay start left active from a previous cycle.
- Text: Observations that place the fault, and the near misses that mean a different one. A machine that starts and then stops with water inside belongs on the cycle page. A machine that runs a full cycle and cleans badly is a wash-performance problem.
Ranked causes on this platform
- Door latch or its switch not reporting closed — Why: The latch is operated on every cycle, it doubles as the safety switch, and a worn catch produces exactly this complaint.
- No supply, a tripped breaker or a switched spur turned off — Why: A built-in dishwasher is often fed from a switched socket or a spur behind a cupboard that gets turned off by accident.
- A condition the machine is signalling by blink pattern rather than by code — Why: Particular to this class of machine: the fault memory is a blink pattern that is lost as soon as the machine is reset, so an owner who resets first and looks second has usually discarded the only evidence there was.
- Delay start, child-lock or a paused cycle — Why: Free to clear and responsible for a large share of these calls.
- Water supply closed or the inlet screen blocked — Why: A machine that cannot fill sits at the start of the cycle with the timer apparently running.
- Flood-protection float raised in the base tray — Why: On machines with a base tray float, any water in the tray latches the machine off entirely — and it looks like a dead machine.
- Control board or selector failure — Why: By exclusion, after everything cheaper has been ruled out.
- A standard part looked for under the retail name instead of the plate — Why: A documentation problem rather than a machine problem: sump filters, spray arms, inlet hoses and drain pumps for this class are stocked items, catalogued against the model and product numbers on the plate inside the door.
- Text: This is a full-size European built-in dishwasher, and two design decisions shape the ranking. The sump is filter-first: the machine expects the owner to clean a filter, and it recirculates whatever that filter fails to catch, which puts the filter at the top of nearly every list. And the machine reports faults by blinking a programme light rather than by printing a code, so the pattern the panel shows is read as evidence rather than looked up as a code. One more factor belongs in the order here: this is a retail house name on a machine built by a mainstream assembler, so the parts are standard European built-in items — but they are catalogued against the plate inside the door rather than against the name on the front.
What to check, in order
- Record the blink pattern before touching anything — Why: On a machine that signals rather than displays, the pattern is the only fault record it keeps, and every reset erases it.
- Confirm the machine has power at its supply point — Why: A switched spur or an isolator behind a cupboard is the commonest hidden cause and takes a minute to check.
- Close the door slowly and firmly and listen for the latch — Why: The latch ranks first among failures, so testing it early either finds the fault or clears the leading suspect.
- Cancel any delay and release the child-lock — Why: high in the ranking and free.
- Check the supply tap and the inlet screen — Why: Placed after the electrical checks because a fill fault produces a machine that begins and waits rather than one that is dead.
- Tilt the machine gently forward and listen for water in the base — Why: Last of the free checks and the one that explains a completely dead machine with a good supply.
- Read the model and product numbers off the plate inside the door before ordering anything — Why: On a house-brand built-in the plate is the catalogue key, and the retail name on the front will not find the part.
- Text: Each step either finds the fault or removes the next most likely cause from the list above.
Step by step
- Note which programme light blinks and how many times it blinks between pauses, and check that pattern against the fault list in the manual before you reset the machine. — Tools: pen and paper, the manual
About 15 min
- Find the supply point — a switched socket, a spur or an isolator in the adjacent cupboard — and confirm it is on. Test it with a lamp if it is a socket. — Tools: a lamp, a torch
About 10 min
- Switch the machine off at its supply for a full minute and back on to clear a latched control state. — Tools: none
About 3 min
- Close the door slowly, watching the catch enter the strike, and listen for the latch click. Press the door firmly while starting a cycle. — Tools: none
About 5 min
- Cancel any delay start, release the child-lock, and select the shortest programme. — Tools: none
About 5 min
- Check the supply tap under the sink is fully open; close it, disconnect the inlet hose at the machine end and clean the mesh screen. — Tools: pliers, a brush, a bowl
About 20 min
- Tilt the machine gently backward a few degrees and listen for water sloshing in the base tray, which indicates a raised flood float. — Tools: none
About 5 min
- Open the door and photograph the plate on the inner frame, recording both the model number and the product number before ordering any part. — Tools: a phone camera, a torch
About 10 min
- Text: Checks a homeowner can safely make. Stop at the first step that would need a meter on live terminals.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the base. A capacitor can hold a charge after the power is off. A dishwasher combines mains voltage with standing water, so isolate it at the spur or the breaker rather than relying on the door switch. Never bypass or tape the door latch to make the machine run with the door open — the latch is what stops hot water spraying into the room.
When to call a technician
Call a technician when the supply is proven live, the latch clicks, no delay or lock is set, the tap is open and the screen is clear, and the machine still does nothing — or when water is heard in the base tray. Supply, latch, settings and screens are owner checks; the flood float, the control and the wiring are not. On a built-in machine the boundary also has a practical edge: the filter, the spray arms, the seal and the drain are reachable with the door open, while anything that needs the machine drawn out of its housing is a service visit.

Common Essentiell Dishwasher Problems — Slug: essentiell-dishwasher-problems — Relation: the routing page for this brand and appliance
This page is generalized information. It covers Essentiell dishwashers as a class: it carries no model numbers, no family-specific error-code table and no wiring detail, because no fact rows for those exist behind it. European built-ins of this generation share sump filters, spray arms, inlet hoses with integral flood valves and drain pumps across several assemblers; the part is matched by the model plate inside the door. On a machine that signals with a blinking light rather than a code, note exactly which light blinks and how many times before you touch anything — that pattern is the only fault memory the machine has. The more specific pages listed below sit beneath this one, and where one of them differs from anything general said here, it takes precedence.
