In short
Burning smells, scorched plugs, tripping breakers and shocks come from the supply connection, from water reaching wiring, or from a motor or heater breaking down under load. None of them improves with another cycle. These platforms decide almost everything in software, so a sensor that drifts rather than fails keeps the appliance behaving plausibly and wrongly. Work the conditions first; the components are the shorter half of this list.
What you actually see
- A hot or burning smell, especially during the spin — Friction or a failing motor circuit under the heaviest load of the cycle.
- The breaker trips at the same point in every cycle — A circuit that is only energised at that point, which identifies itself.
- Scorching or melting at the plug or socket — A connection making heat rather than contact.
- NEAR MISS: a burning smell only from newly washed clothes — That is usually detergent or fabric rather than the machine.
The causes in order of likelihood
- Heating circuit failing to earth — The one to suspect first. It leads because loosened connections make heat under load, and a washer loads its supply harder than almost anything else in the house. An element that has broken down internally trips protection as soon as it is energised.
- Motor or motor-control failure — The second suspect. A motor breaking down under load trips protection during spin, which is why the fault so often appears at the same point in the cycle.
- Loose or overheated supply connection — Third, and less common. A washer draws hard while heating and again at spin, and a connection that has loosened makes heat at exactly those moments.
- Water reaching wiring or a connection block — Fourth, and less common again. A leaking hose, pump seal or tub seal drips onto wiring beneath the machine. Water plus an electrical symptom is one fault, not two.
- Body: The order below is what makes this page worth reading. It is a ranking rather than a measurement, and it carries no numbers because no fact bundle supports any.
The diagnostic order
- Switch off the circuit at the breaker — Everything else here is done on a dead machine.
- Inspect the plug, socket and cable for heat damage — Discolouration and a hot-plastic smell both point at the same place.
- Note the point in the cycle at which the fault occurs — Fill, heat, wash or spin: each convicts a different circuit.
- Body: The order below is done with the machine isolated. There is no owner-side live test in this category.
What you can do now
- Isolate at the breaker and leave the machine unused — Do not run a cycle to reproduce the symptom.
- Photograph any scorching before touching anything — It is the evidence that tells a technician where to start.
Tools: torch
- Check whether anything else on the circuit is affected — A circuit-wide symptom moves the investigation out of the machine.
- STOP. Do not open the casing or test anything live — A washer casing holds a heavy drum and live connections, and neither is an owner task.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. If anyone has felt a shock from the machine, leave the circuit off and do not use it again until it has been checked.
When this becomes a service call
Every symptom on this page is a service call. Isolate the machine, keep a note of where in the cycle the fault appeared and what you smelled, and have it checked before it is used again. Describe what you heard as well as what you saw; both narrow it.

What this page does not cover
This page is written for the appliance class rather than for one Blomberg family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and should be preferred over this one; the brand and appliance hub linked below routes to everything more specific that exists today.
