How to reset your boiler

As experienced plumbers serving the Medway, Dartford, and Gravesend areas, we often receive calls about boiler issues that can be resolved with a simple reset. While we're always here to help, we want to share our professional knowledge to help you understand when and how to safely reset your boiler.

Why Boilers Need Resetting

A boiler might need resetting for several reasons:

• After a power cut

• Following a system error

• When the boiler has locked out for safety

• If there's been a temporary interruption in the gas supply

• When water pressure has dropped too low

Before You Reset Your Boiler

Check the Power Supply

First, ensure your boiler is receiving power. Check if other electrical appliances are working and look at your fuse box for any tripped switches.

Check the Gas Supply

Verify that your gas supply is working by checking if other gas appliances are functioning correctly. Look at your gas meter to ensure the supply hasn't been interrupted.

Check the Water Pressure

Look at your boiler's pressure gauge. The ideal pressure should be between 1 and 1.5 bar. If it's lower, this might be why your boiler has stopped working.

How to Reset Different Types of Boilers

Combi Boilers

Most modern combi boilers have a dedicated reset button, typically marked with a red light or LED display. The process usually involves:

1. Locating the reset button on your boiler's control panel

2. Pressing and holding the button for about 10 seconds

3. Waiting for the boiler to complete its reset cycle

4. Checking if normal operation has resumed

System Boilers

System boilers often have a similar reset process to combi boilers, but might require:

1. Turning the boiler off completely

2. Waiting for 5 minutes

3. Turning it back on

4. Pressing the reset button if available

Regular Boilers

Older regular boilers might need:

• Checking the pilot light is lit

• Following the manufacturer's specific reset sequence

• Ensuring all controls are in the correct position

When Not to Reset Your Boiler

While resetting can solve many issues, there are times when you shouldn't attempt it:

• If you smell gas

• If the boiler is making unusual noises

• If you've already reset it multiple times without success

• If there's visible damage to the boiler

• If you notice water leaking from the unit

In these cases, it's essential to contact a professional plumber immediately.
