The quick verdict
An ASKO washer that trips a protective device, smells hot or gives any tingle should be isolated at the breaker immediately. Then make one observation: does the device still trip with the machine unplugged? Yes means an electrician; no means an appliance technician. Do not run further cycles to gather more evidence.
What the machine is doing
- A protective device tripping during a cycle — Appliance-side, most likely at the heating stage.
- A device that trips with the machine unplugged — House-side. An electrician, not a technician.
- A hot or acrid smell during a cycle — Overheating insulation or a connector. Isolate.
- A tingle from the cabinet or nearby plumbing — An earthing question, and an electrician's call.
- A warm plug or discoloured socket — Both trades may be needed; the socket is the house's.
What is behind it, in order
- Heating element failed to earth — First, and the commonest appliance-side cause.
- Water reaching wiring inside the machine — Second, and it usually follows a small internal leak.
- Motor or capacitor failure — Third, and it tends to show at spin.
- Socket or plug degradation — Fourth, and it belongs to the house side.
- Circuit or earthing fault — Last, and it is what the unplugged test reveals.
A sequence that saves time
- Switch off at the breaker and unplug the machine — First action, no exceptions.
- Reset the device once with the machine unplugged — It sorts the fault between two trades in one step.
- Note where in the cycle the trip occurred — Fill, heat, wash or spin — each points elsewhere.
- Stop — Everything past this needs an instrument and somebody qualified.
The checks you can run yourself
- Isolate at the breaker and unplug the machine — Do not run another load to confirm the symptom; it will confirm itself.
About 5 min
- Reset the protective device once, machine unplugged — Holds means the appliance. Trips again means the circuit, and that is an electrician.
Tools: torchAbout 10 min
- Write down the point in the cycle where the trip happened — It is the most useful single fact for whoever attends.
About 5 min
- Inspect the plug, flex and socket for heat damage — Discolouration means an electrician replaces both. Stop here.

Power off, panels later
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and a washer's motor capacitor holds enough to injure in a wet room. A standard household branch circuit is 15 A or 20 A. If anybody has felt a shock or tingle from the cabinet, the taps or nearby pipework, stop using the machine and treat it as an earthing fault: that symptom is about the house's protective earthing as much as the appliance, and it is checked before the machine is used again.
When to stop and book someone
Call an electrician first when the device trips with the machine unplugged, when the socket shows heat damage, or when anybody has felt a tingle. Call an appliance technician when the trip only happens while the machine runs, and tell them at which stage. Keep the machine isolated until one of them has attended, and do not move it to another socket to keep using it: that relocates a hazard rather than resolving it.

Where this page stops
This page covers the ASKO washer class and stops where measurement begins. It publishes no element ratings, insulation figures or wiring colours, because those differ between builds under this badge and because publishing them encourages exactly the unsafe testing this page exists to prevent. Household wiring, earthing, sockets and protective devices belong to a licensed electrician rather than to an appliance technician.
