Stop first if there are danger signs
If there is gas smell, a CO alarm, burning, overheating or a serious electrical concern, stop use and seek appropriate help. For suspected CO exposure, get outside and follow medical advice. Do not keep an appliance running while trying to understand an unsafe symptom.
Check current guidance: NHS carbon monoxide advice.
Identify the appliance and operating mode
Record the make, model, selected energy source and exact error message. Note when the problem occurs and whether it changes on another supported mode. A model label and a clear account are more useful than describing every appliance as simply “not working”.
Check only what the manual permits
Only perform checks the manual permits: for example confirming the selected mode and that the expected supply is available. Do not dismantle gas fittings, mains electrical components or protective equipment. Stop if you cannot understand the instructions or safely access the area.
Choose the right repair specialist
Choose a specialist with the relevant appliance and fuel or electrical competence. Ask about diagnosis, access and parts, especially for older equipment. A general vehicle garage may not service living-area appliances.
Record the outcome
Keep the repair record and understand what was tested afterward. If the same fault returns, report the conditions rather than repeatedly clearing it. Make sure any untested mode or unresolved concern is documented.
Questions you might still have
Why does the fridge work on one energy source but not another?
Separate modes may have different supplies or components. Record the working and failing conditions and follow the appliance’s permitted checks.
Should I keep resetting a heater fault?
No. Repeated faults need appropriate investigation, particularly with danger signs. A temporary restart does not establish safe operation.
What model information helps a repairer?
Provide the make, model, energy mode, error message and conditions. Photographs of the identification label can help if it is safely accessible.
Your next useful step
- Stop for danger signs.
- Record the exact appliance and mode.
- Use only permitted manual checks.
- Arrange suitably qualified diagnosis for unresolved faults.
