The short answer
Stop using the machine. A Hotpoint dishwasher that trips its protection, smells of hot insulation or gives any sensation of shock has a fault where water has reached something live, and a dishwasher is full of water by design. Isolate at the breaker, then make the observations below without powering the machine up again to reproduce the fault.
Causes, ranked for this Hotpoint dishwasher
- A leak that has reached electrical components — Why: A dishwasher leaking internally puts water onto wiring and the element, which trips the protection and is the mechanism that turns a plumbing fault into an electrical one.
- Heating element breaking down to earth — Why: An element failing to earth trips the circuit precisely when heat is called for, which is why the trip is timed to the wash or dry stage rather than to the start.
- Damaged supply cord or overheating socket — Why: A machine pushed into its housing repeatedly can trap or chafe its cord, and a loose socket connection generates heat at the plug — an electrician job rather than an appliance one.
- Pump or motor winding insulation failing — Why: A motor breaking down trips under load and often smells before failing outright, and it cannot be confirmed without a meter.
- Missing or interrupted earth connection — Why: A compromised earth leaves metalwork at potential rather than clearing the fault, which is what turns an internal defect into a shock at the door.
What to check, in order
- switch the circuit off at the breaker and stop using the machine. — Because: every symptom here means a live conductor has already gone where it should not.
- look at the socket and plug for heat damage, melting or a loose fit. — Because: a supply-side fault is common, dangerous, and visible without opening anything.
- note exactly when the trip happens in the programme. — Because: the timing separates the element from the pump and is what the technician needs.
- check the floor and the base of the housing for water. — Because: a leak reaching electrics explains the trip and changes the urgency entirely.
Checks you can safely do yourself
- Switch the dishwasher circuit off at the breaker and leave it off; do not run a programme to reproduce the fault. — Tools: none — Time: a minute
- Unplug the machine where it is plug-connected and inspect the plug and socket for discolouration, melted plastic or a loose fit. — Tools: a torch — Time: several minutes
- Look along the visible length of the supply cord for crushing or chafing where the machine sits in its housing. — Tools: a torch — Time: several minutes
- Check the floor beneath and the base of the housing for water, and note whether any has been there long enough to mark. — Tools: a torch and a cloth — Time: several minutes
- Write down when the trip or smell occurs relative to the programme. Stop here: nothing inside the machine should be opened or metered by an owner on this fault. — Tools: none — Time: several minutes
Before you open anything
Safety
unplug-before-service branch-circuit-15-20a
Do not use a dishwasher that has given anyone a shock, that trips its protection, or that smells of burning, and never reset a breaker repeatedly to finish a programme. Keep the circuit off until it has been assessed. A machine that has leaked onto its wiring must not be run again even if it appears to work.
Where the owner fix ends
The observations above are owner work; the repair is not. Call a technician for any trip, burning smell or shock, since each requires insulation and earth-continuity testing with instruments. Call an electrician instead when the socket, plug or cord shows heat damage, or when other appliances trip the same circuit.
