What this usually is
Anything electrical on a DECO HOME dishwasher — a burning smell, a tripping breaker, scorching at a connector — is a stop-now fault rather than a diagnose-later one. Isolate the machine first and investigate afterwards. It matters that this is an online home-goods line whose dishwashers are compact and countertop units rather than fitted machines, because that is what decides the order below.
What you observe
- The protective device trips when the machine is switched on — A fault to earth somewhere in the appliance or its supply.
- Scorching or discolouration at a plug or connector — A loose connection has been arcing, which is a fire risk rather than a nuisance.
- The device trips only partway into a cycle — Points at the heater, because that is when it energises.
- NEAR MISS — the machine simply will not start — That is a start fault; check the supply and the latch first.
Ranked causes for this brand and appliance
- Heating element failed to earth — The signature is a trip that happens at the same point in every cycle, which is when the heater energises.
- Supply connection loose or overheating — This is a fire risk in its own right and it is a job for an electrician rather than an appliance technician.
- Water reaching an electrical component — A slow leak inside the cabinet wets a connector or the control, and the fault appears intermittently and then permanently.
- Damaged mains lead — It usually trips on movement rather than at a particular point in the cycle.
- Pump or motor winding failing — It is less common than a heater fault and produces the same repeatable trip point at a different phase.
What to check first, second, third
- Note whether the trip happens at the same point in the cycle every time — First — A repeatable trip point identifies the component that energises at that moment.
- Look at the plug, the socket and the spur for discolouration or a smell of hot plastic — Second — Visible scorching means the fault is on the supply side and needs an electrician now.
- Look for signs of water inside the cabinet base or at the door skin — Third — It links two symptoms into one cause and changes the urgency.
The owner-side checks, in order
- Look at the plug, socket and spur for scorching — Discolouration or a smell of hot plastic means an electrician rather than an appliance technician.
Tools: torchAbout 10 min
- Check the mains lead along its whole length — With the supply off, feel for crushing, cuts or hardening.
About 10 min
- STOP — do not reset repeatedly and do not open the machine — A device that trips again is reporting a real fault; resetting it repeatedly is unsafe.

Safety
Isolate the dishwasher at the breaker before touching anything, and leave it isolated until a technician has seen it. A capacitor can hold a charge after the power is off. allowlist:unplug-before-service allowlist:branch-circuit-15-20a
Where the owner fix ends
There is no owner-side repair on this page. The owner-side actions are to isolate, to observe when the trip happens, to look for visible scorching, and to leave the machine off until it has been seen. Worth saying to whoever attends: these units stand on a worktop or roll to the sink, and are connected to the tap only for the wash.

What this page does not cover
This page covers the DECO HOME dishwasher as a class rather than one family or model line. Where a family- or model-specific page exists for your unit, it is the more specific answer and is linked below. Not covered here: element ratings, circuit specifications and the internal wiring layout, which differ by model line and are an electrician or technician matter.
