How To Reset a Potterton Boiler

Modern boilers have multiple safety features, including those from Potterton. When these newer models encounter an issue, they activate a lockout mode, which prevents the boiler from damaging itself.

As you can imagine, there are multiple reasons why a boiler will shut itself down and now require a proper reset.

Before starting the process to reset your Potterton boiler, check if the unit is displaying an error message.

Common Potterton Boiler Error Codes

There are common reasons why a modern boiler will activate lockout mode. Luckily, the boiler will display error messages to inform you what has gone wrong.

Here is a list of common error codes:

It’s important to note that these codes can vary depending on the Potterton boiler’s model and age. Always consult your Potterton manual to confirm your error code.

Now that we have an idea of what that error code could mean, let’s discuss the different methods for resetting your Potterton boiler.

Methods Of Resetting Your Potterton Boiler

For Potterton boilers, there are generally two reset methods:

Reset Button

Most Potterton units (e.g., Promax Combi) feature a dedicated reset button on the control panel. Press and hold it for 3–5 seconds until the boiler restarts.

Control Dial Reset

Some models (e.g., Titanium Combi) require you to turn the selector switch to the “Reset” position, hold for a few seconds, and then return it to “Hot Water/Heating.”

Once you’re certain which method your Potterton boiler needs, let’s reset your Potterton boiler.

Steps To Reset Potterton Boiler

It’s incredibly easy to reset your Potterton boiler if you follow these steps:

Step One: Identify the Error Code

Before resetting, remember to jot down or take a photograph of the error code.

There’s nothing worse than forgetting what the error code was and having to go through the steps again.

Also, if you are required to explain the fault to a Gas Safe registered engineer, there’s no confusion.

Before you perform a reset, you want to be sure that you’ve done some troubleshooting, which will most likely require performing one of the following tasks:

Check The Gas Supply

If you see the error code E133, or an ignition failure or no gas supply fault, you will want to perform a quick and simple check of the gas mains.

To ensure the mains valve is open, test another gas appliance, such as your home’s hob, to check if it has a gas supply issue. If you discover that the gas mains were accidentally shut off, simply open it up.

However, if you suspect a more significant issue, such as discovering that other appliances are not functioning, contact your gas provider immediately.

Check The Water Pressure

Potterton boilers typically operate between 1.0 and 1.5 bar when cold.

If pressure is too low, you will need to repressurise the heating system via the filling loop.

For boiler systems with a pressure that’s too high, you will need to bleed a radiator to bring it down.

Check The Power Supply

Another troubleshooting task you can perform as a homeowner is to check the boiler’s power supply.

Close to your boiler should be a fuse spur. If you’re uncertain what a fuse spur is, it’s a square white box with a large switch in the middle.

Flip this switch on and off.

Allow a few seconds for the boiler to shut down.

Sometimes, a boiler is simply plugged into a socket, and you just need to flip the switch.

If you cannot locate your boiler’s plug point, try switching it off and on at the distribution board, also known as:

• Panelboard
• Circuit breaker panel
• Breaker panel
• Electric panel,
• Fuse box,
• Or DB board/box.

Once you’ve turned the power back on, your Potterton boiler should have automatically reset itself. However, if you were troubleshooting for gas and pressure issues, you would need to perform the reset.

Step Two: Perform the Reset

Use the reset button or dial method, depending on your Potterton model.

After a minute or two, the boiler should reignite.

Test both hot water and heating to confirm everything is working correctly.

If, however, you perform this hard reset and your Potterton boiler is still displaying an error code, we’d strongly advise calling in a professional.
