What is most likely happening
Electrical symptoms on a washer are not a category to work through patiently — they are a stop-and-isolate situation. The good news is that the common causes are specific and a technician can confirm them quickly; the bad news is that none of them are owner repairs. On a Avanti washer the order below is what makes this page worth reading — the causes are ranked for this kind of machine, not listed alphabetically.
What you observe
- The breaker or the earth-leakage device trips when the machine runs — Often at a particular point in the cycle, which is itself the clue: a trip when the heater comes on is a different fault from a trip at the spin.
- A faint tingle from the cabinet or the taps — Stop using the machine now. That is current finding a path it should not have, and it can be a fault in the appliance or in the earthing of the outlet.
- A hot-plastic or fishy smell around the panel or the plug — Overheated insulation smells like that. It usually comes from a connection rather than from a component.
- Scorching or discolouration at the plug or the outlet — A loose connection generates heat every time the machine draws current, and it gets worse each cycle.
- NEAR MISS — the machine simply does not power up at all — A dead machine with no smell and no trip is a supply or no-start question, and that is a different page.
Ranked causes on this platform
- Heater element breaking down to earth — Ranked first on any washer that heats its own water: the element sits in the sump, it corrodes from the outside, and the failure mode is a leak to earth that only shows up when the element is energised. That is exactly why the trip happens partway into the cycle rather than at switch-on.
- Water on a connector, a motor or the board — Second, because a washer that has leaked has usually leaked onto something electrical. Dried-out boards work intermittently, which produces the maddening pattern of a machine that trips on some cycles and not others.
- A damaged supply cord or an overloaded outlet — Third: the cord gets pinched behind the machine when it is pushed back, and the damage is on the side nobody looks at. Shared outlets and extension leads belong in this rank too.
- Motor or capacitor insulation failure — Last of the four, and the one most likely to arrive with a smell rather than a clean trip. It ranks low because it is genuinely less common than the heater, not because it is less serious.
Working through it
- Note exactly when in the cycle the trip happens — Wash-heat, spin or fill — each points at a different circuit, and it is the single most useful thing an owner can hand a technician.
- Check whether other appliances on the same circuit trip it too — That separates an appliance fault from a circuit fault before anyone opens anything.
- Look at the plug and the outlet face for heat damage — Done with the plug out. Browning, melting or a loose pin explains the smell without going any further.
The owner-side checks
- Stop using the machine and unplug it — This is the first step, not the last. A machine that trips or tingles stays off until it is diagnosed.
About 5 min
- Record the cycle point at which it trips — Run nothing new to find out — use what already happened. If you must confirm, do it once and stop.
About 5 min
- Inspect the cord along its whole length — Pull the machine forward and look for crush damage where the cabinet meets the wall. A pinched cord is visible and it is the one cause an owner can definitively find.

- Look under and behind for signs of a past leak — Water marks, rust tracks or a salt bloom on a bracket tell you where the water went, and electrical faults follow water.

- STOP — do not open the cabinet on an electrical fault — Insulation testing needs an instrument and a method. This is the point where the job is a technician visit, without exception.
Power, water and the limits of owner work
Safety
Unplug the machine or switch off its breaker before removing a panel, and close the water supply before touching a hose or a fitting. Components inside can hold a charge after shutdown. Never run the machine with a panel off or with the lock defeated — the interlock is a safety device, not an inconvenience.
When this stops being a home job
Call immediately, and leave the machine unplugged until someone has looked at it. A breaker that trips is doing its job, and resetting it repeatedly to finish a load is the one action that turns a contained fault into a fire or a shock. Any tingle from the cabinet or the taps is an emergency-grade symptom: it means the earth path is compromised somewhere between the appliance and the supply, and that is licensed work in both directions.

What is deliberately left out
Treat this as the generalized Avanti washer page. It is written to be true across the platform, which means it stops short of the details that only hold for one family — connector pinouts, specific board revisions, the order the cabinet comes apart in. Those live on the family- and model-level pages linked here, and where one exists for your unit, that page outranks this one.
