What To Do If Your Boiler Stops Working

When your boiler stops working, here are the key checks to make in order of priority:

Safety first:

• Check for any gas smells - if you smell gas, don't use electrical switches, open windows, and call the gas emergency line immediately on 0800 111 999 

• Ensure the boiler area is well-ventilated

Basic checks you can do:

• Power supply - Check if the boiler is getting electricity (look for display lights or error codes)

• Gas supply - Try other gas appliances like your hob to see if gas is reaching your home

• Water pressure - Look at the pressure gauge on your boiler (should typically be between 1-2 bar when cold)

• Thermostat settings - Ensure your thermostat is set above current room temperature and is calling for heat

• Timer/programmer - Check if heating is scheduled to be on

• Pilot light - On older boilers, check if the pilot light is lit (blue flame)

Simple fixes to try:

• Reset the boiler using the reset button (usually red, hold for 10 seconds)

• Check your fuse box for any tripped switches

• Bleed radiators if they're cold at the top but warm at the bottom

• Top up water pressure if the gauge shows low pressure (consult your manual for the filling loop)

When to call a professional:

• If you smell gas

• If there are error codes you can't resolve

• If the boiler is making unusual noises

• If you're uncomfortable doing any checks

• If basic checks don't resolve the issue

Most boiler problems require a Gas Safe registered engineer, so please call Milards if you're unsure about anything.
