The short answer
A dishwasher that does nothing is usually not broken in the way it looks. The door latch, the power supply and the control lock account for most of them, and all three are checkable in a few minutes without tools. On a Euhomy dishwasher the place to start is the control lock or a delayed start, because a countertop or slimline machine has a short drain path and a small filter bowl, so the parts that silt up first are the ones nearest the sump.
What you actually observe
- The cycle starts and stops within a minute — It began, failed a check it makes early, and stopped.
- Nothing at all when the door is closed and start is pressed — No lights, no sound.
- Lights come on but the cycle never begins — The machine has power and has decided not to proceed, which is a different and more informative fault.
- NEAR MISS: it runs but never fills — That is a fill fault, not a start fault, and the checks are different ones.
Causes, most likely first on this brand
- A child lock, a demo mode or a delayed start already set — Almost every machine has a key lock that disables the panel, and most have a delay timer. Ranked first on a Euhomy dishwasher: these are compact units sold online and used harder than their size suggests, so how they are loaded and how full they are kept drives the failure profile more than any component does.
- The door latch is not making its switch — No dishwasher will run with the door circuit open, and it is the latch rather than the door that decides. Where it sits here: the most common cause of a dead dishwasher on any machine, because the latch is a moving part used several times a day.
- The supply valve is closed or the inlet is blocked — A machine that starts and stops within a minute has usually failed its fill check. Where it sits here: ranks here because it explains the specific pattern of a cycle that starts then quits, rather than one that never begins.
- A failed touch panel or control board — Membrane panels lose contact with age, particularly at the buttons used most, and a board that has taken a surge simply does nothing. Where it sits here: last, because every cause above it is more common and cheaper, and this is the only one needing a meter.
Check in this order, and why
- Start at the control lock or a delayed start — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Open and close the door firmly and try again — Lift the door slightly as you push it to.
- Check the spur switch and the breaker — The switch behind the adjacent cupboard is the single most-overlooked cause of a dead machine in a fitted kitchen.
What an owner can safely do
- Reseat the racks and close the door with a lift — Pull the lower rack fully in, check nothing is standing proud of the inner door, then close it with slight upward pressure on the handle.
About 5 min
- Power-cycle the machine at the breaker — Off for a minute, then on.
About 10 min
- STOP HERE before opening the door panel — The latch switch and the control board are behind the inner door skin, and they are measured live.
Before you open anything
Safety
Switch the machine off at the wall or its breaker before opening any panel; a capacitor can hold a charge after the power is off. Never defeat the door latch to make a machine run with the door open, because that switch is what stops the pump spraying hot water into the room. If the breaker trips again as soon as it is reset, leave it off and call.
When to call a technician
Call when power is proven at the socket, the latch is proven to close its switch and the panel still does nothing, or when the breaker trips each time the machine is switched on. A machine that trips a breaker is a machine with an earth fault, and that is the one version of this fault to stop using immediately.

What this page does not cover
This page covers Euhomy dishwashers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: latch and board part numbers, panel membrane references and the service-mode key sequences, all of which differ by family.
