The short answer
Heat plus lint is the hazard that defines this appliance class, so an electrical complaint is stopped rather than nursed. A facility machine is usually installed to a building standard, which makes the supply side well documented and moves suspicion onto the machine itself.
What you actually observe
- The plug or receptacle is warm after use — Resistance where there should be none. Check whether it happens every time or only sometimes.
- A hot or scorched smell during the cycle — Something is running above its intended temperature.
- The machine is fed through an adapter — That is the fault. Whether it happens constantly or in bursts changes the answer.
- NEAR MISS — heat stops partway through and returns next cycle — A thermal device is resetting. If that is your Direct Supply dryer, the bottom of the ranking below is where to start — and this may not be the nearest page for it.
Causes, most likely first on a Direct Supply dryer
- Heat damage at the plug — Most likely on this platform. A machine that was moved, reconnected or converted between supply types is the one where this is found. It stays at this place in the Direct Supply dryer order until the checks above it are clean.
- Lint in the cabinet and the duct — Second. It is free to correct and it is the one cause here an owner can genuinely resolve.
- An improvised or shared supply — Third. Extension leads and adapters on a heating appliance are a fault in themselves. It stays at this place in the Direct Supply dryer order until the checks above it are clean.
- A safety device doing its job — Least likely, and the most expensive. It ranks here because a machine that keeps stopping on its thermal protection is reporting a restriction rather than a failure.
What to check first, second, third
- Step one: With the breaker off, look at the terminal block behind the access cover. — It is the cheapest thing to prove on a Direct Supply dryer.
- Step two: Feel whether the outlet flap outside actually opens when the machine runs. — This is the check that tells the two mid-list Direct Supply dryer causes apart.
- Step three: Check for any adapter or extension lead in the supply. — This is the check that confirms the expensive answer on a Direct Supply dryer, so it comes after the cheap ones.
What an owner can safely check
- Switch off the breaker before any inspection — Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off.
About 5 min
- Clear the whole exhaust run — Disconnect the duct at the machine and clear it end to end, including the outside flap.
Tools: vacuum, duct brushAbout 45 min
- Remove any temporary lead — A heating appliance on an extension lead should be shut down until it is wired properly.
About 10 min
- Go no further than the checks above — Everything beyond them on a Direct Supply dryer is behind a panel or on a live terminal, which is the boundary this page keeps.
Before any panel comes off
Safety
None of the checks on this Direct Supply dryer page require a live appliance. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Let the appliance come down to room temperature before reaching inside; a cavity or a drum holds heat long after a cycle ends. Lint is fuel and this appliance makes heat, so a restricted exhaust is a fire question rather than a performance one. Do not test elements or terminals with the appliance energised, and do not bridge a protective device that has operated.
Where the owner side ends
On a Direct Supply dryer the handover point is easy to define. An overheating symptom is a fire question, and the right response is to stop using the appliance now rather than to finish the diagnosis. If a check needs nothing more than your hands, a vacuum and a torch, it is yours; if it needs a meter on a live terminal, it is a technician.

The limits of this page
Read this as the class-level answer for a Direct Supply dryer; anything more specific to your model lives on its own page. Where a family- or model-specific page exists for your unit it is the more specific answer, and it is the one to read first if your model is named on it. The DIRECT SUPPLY Dryer Problems overview links them together. What is deliberately not here: wiring colours, torque figures, part numbers and service-mode sequences, all of which differ by family and belong on the page for that family.
