What this usually is
An Arctic Wind dishwasher that trips the household protective device, smells of hot plastic or shows scorching at its plug has a fault with a fire or shock dimension and should be isolated rather than run again. Owner work here is limited to observation: when it trips, what the plug and socket look like, and whether the circuit misbehaves with the machine unplugged.
What you actually see
- A trip that repeats at the same point in the programme — Almost always the heating element leaking to earth, because that is when it is energised.
- Trips at unpredictable points — A harness or a pump winding, and much harder to catch.
- A hot plastic or fishy smell near the socket — Overheating insulation at a poor joint. This is a fire precursor.
- Discoloured or melted plug pins — A long-running high-resistance connection. The socket needs replacing as well as the plug.
- Any tingle from door, trim or worktop — An earthing fault. Stop, isolate, and call an electrician today.
Ordered by what we actually find
- Heating element earth leakage — First for repeatable trips, because it is the mains component permanently under water.
- Damaged flex or a pinched cable — Second, and this is where the what-changed question pays: cables get crushed during kitchen work.
- A degraded plug or socket — Third. Produces smells and heat damage rather than clean trips.
- Water in the base tray or on wiring — Fourth. A tolerated leak ends here, weeks or months later.
- A house fault rather than an appliance one — Also common: an ageing protective device, or another appliance on the same circuit.
Check them in this order
- Note when the trip happens — Fill, heat or random. Three groups of causes.
- Unplug and inspect the plug, flex and socket — Visible damage means part of the fault is in the house.
- Reset once with the appliance unplugged — If it still trips, the machine is innocent.
- Stop there — Insulation testing is done on an isolated machine by somebody insured for it.
The checks you can run yourself
- Isolate at the breaker and unplug the machine — Then leave it isolated. On this page that is the instruction rather than a preamble.
About 5 min
- Inspect the flex along its whole length — Look behind the machine and under the plinth for crushing, especially if work has been done recently.
Tools: torchAbout 15 min
- Examine the plug pins and the socket face — Discolouration or melting means both are replaced, not just the plug.

- Look for water tracks under and behind — Dried mineral trails record leaks that are dry today. Stop here.

What can hurt you here
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A standard household branch circuit is 15 A or 20 A, and a fault on it can start a fire inside a cabinet before anyone smells anything. Never fit a higher-rated device to stop nuisance tripping, never run the machine on an extension lead, and if you smell burning during a cycle kill the circuit at the consumer unit rather than pulling a plug that may itself be the hot part.
What is not a homeowner job
Call at the first appearance of any symptom here and leave the machine isolated until someone has measured it. Call an electrician first when the socket is damaged, when the circuit trips with the appliance unplugged, or when anybody has felt anything through a metal surface. Call an appliance technician when the circuit is proven sound and the fault follows the machine, and tell them which phase it trips in, because that decides what they bring.

Scope of this page
This page covers the Arctic Wind dishwasher class and stops where measurement begins. It publishes no element resistances, no wiring colours and no terminal layouts, because those differ between builds under this badge and because publishing them invites unsafe work. Household wiring, sockets and protective devices are outside this page and belong to a licensed electrician. Where a family- or model-specific page exists, it carries the component layout for that build.
