- If your gas appliance has a plug, check whether there is power at the socket. For example, you can connect another appliance to test this. Is there no power? Then check the fuse in the meter cupboard.
- Are the gas taps under the boiler open? And what about the main tap in the meter cupboard?
- Check whether the water pressure of the central heating system is above 1 bar. If this is not the case, top up the water pressure to a maximum of 1.8 bar (see topping up).
- Set the room thermostat to at least 30°C and see whether the boiler starts. If this happens, there may be a problem with the thermostat. If the boiler does not start, report this as a fault.
- Does your gas appliance have a pilot light? Check whether it is lit. If not, try to light the pilot light again.
- If your thermostat works on batteries, the display will indicate when they need to be replaced. Always use alkaline batteries.
- Does the appliance have a reset option? Try using it, or remove the plug from the socket and reinsert it. Make sure you note down any fault codes and report them when you receive a report.
- If you do not have hot water at a tap, but do have it elsewhere, there is a good chance that the perlator (the sieve) or the shower head is blocked.
- Do you have hot water, but the central heating is not working? Check that there is no leaking hot water tap. This can cause the gas appliance to remain in the hot water position and not switch over to the central heating.
