How to diagnose hot water loss
If there's an issue with your hot water supply, follow our tips to help you diagnose the problem.
Check the Power Supply
Make sure that there is actually power going to the boiler.
If you can't turn it on then check that all switches are on and the fuse hasn't gone in the plug.
Try putting a new fuse in the plug and seeing if this sorts out the problem.
Check the Pump
Have a quick check to make sure that your pump is running by feeling the side of the pump for motion. If it doesn't appear to be running, you will need to get a heating engineer in to investigate.
Check the Thermostat
Check that your thermostat is switched on and not set too low.
You should also check that the power switch is turned to ‘On' and that the thermostat controlling the water temperature is set high enough.
Check the pilot light
Make sure that the pilot light is lit. If it isn't, then your water definitely won't be hot.
To re-light it, follow the instructions in the manual or on the boiler.
If none of these checks solve the problem then it's time to call in a Gas Safe Register heating engineer.
