Start here
A Deco Home dishwasher that does nothing when you press start is most often held by its door latch or by a setting rather than by a failed board. Work down the ranking below: the first three causes account for the great majority of these calls and none of them need tools.
What you are seeing and hearing
- The whole unit is affected at once rather than one part of it — A compact machine has one small circuit, so nothing here fails by halves.
- The lights come on only when the door is pressed hard — That is the latch, and it is a complete diagnosis on its own.
- NEAR MISS: the machine starts and then stops part-way — That is a cycle fault and belongs on a different page.
The causes, most likely first on this brand
- No power reaching the machine — Dishwashers are commonly fed from a switched socket in the adjoining cupboard or a spur switch above the counter. Ranked first on a Deco Home dishwasher: this is proved in a minute and it rules out the whole list below it.
- A shared or protected circuit that has tripped — Where a kitchen circuit is protected, a fault anywhere on it takes the dishwasher with it. Ranked second on a Deco Home dishwasher: these are routinely pushed under a counter or built into a cabinet, and the clearance the manufacturer asks for is rarely there.
- A delay timer, a control lock or a programme not confirmed — Most machines can be locked against children, and most offer a delayed start. Ranked third on a Deco Home dishwasher: a small cabinet is overfilled more often than a large one, and the symptoms of that look like a fault.
- The door latch not making — No dishwasher will start with a latch that does not close its switch, and a latch can fail to make while the door still feels shut: a plate handle in the way, a hinge that has dropped, or a worn catch. Ranked fourth on a Deco Home dishwasher: the electronics are minimal on a unit this size, so there is less of it to go wrong than owners expect.
Check in this order, and why this order
- Find the switch or socket that feeds the machine and check the breaker — A completely dark panel is a supply story until proved otherwise.
- Check whether other outlets on the same circuit are also dead — Several things dead at once is a circuit, not an appliance.
- Look for a lock or delay symbol and read what the panel is showing — A symbol nobody recognises is the answer surprisingly often.
Owner checks, in order
- Switch the spur or socket back on and check the breaker at the panel — Check the socket with something else before assuming the machine is at fault.
About 10 min
- Reset the protective device once and see whether it holds — If it trips again immediately, stop and get the circuit looked at.
About 10 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch off the breaker before removing the lower panel or the door skin: the heating element and the junction box are both live under the machine, and there is standing water in the sump. Never defeat the door latch to watch a cycle run. Let a hot machine cool before you reach into it.
When this becomes a service call
Call when the supply is proved, the door latches, the taps are on and no lock or delay is set, because what remains is the latch switch, the board or the panel. Call sooner if a breaker trips whenever the machine is switched on, and do not keep resetting it: repeated tripping is the circuit telling you something real.

The scope of this page
This page covers the Deco Home dishwasher as a class, not one family or model line. Filter designs, sump layouts, wash-arm arrangements and part numbers differ between builds and are deliberately left out. Where a family- or model-specific page exists for your machine, go there first: it is the more specific answer.
