E119 Boiler Fault And How To Fix E119 On Your Baxi Potterton Boiler

Handling a problem with your boiler doesn’t have to be overwhelming; the solution comes in knowing what the fault code actually means, allowing you to take swift, decisive action.

What is a E119 Error Code?

An E119 error code will usually point to low boiler pressure, and this can have a number of different causes, including water leaks on your central heating system pipework.

In most cases, a E119 fault on a Baxi Potterton boiler indicates that there is water leaking somewhere in the system, and this is a job usually best handled by the professionals; leaks can be tricky to track down, and may require specific specialist knowledge to repair and rectify. This is very similar to the Vailliant F75 boiler fault code. We have also published a guide to Worcester Bosch Boiler Fault Codes.

How To Fix The E119 Fault Code

An E119 fault means that your system is not functioning correctly, and this will typically result in a lack of heating and hot water. Repressurising the system is usually a fairly easy job and can be a great way to monitor the situation – if the pressure suddenly drops again, this is a strong indication that there is a leak or flaw in your boiler, pipes or radiators.

Please only follow the steps if you are competent and have also read the manual for your particular boiler.

How To Increase The Pressure Of My Baxi / Potterton Boiler

To repressurise your boiler, you need to just follow a few simple steps:

  • Turn the boiler off before commencing, and always ensure that the system has had a chance to cool down completely before you try and touch anything – the last thing you want is a painful burn.
  • Once you are convinced that everything is cool, you need to locate the filling loop. This is constructed from a metal hose, with two valves – one at either end – and should be easily identifiable.
  • Check to see whether your pipes have end caps; if so, you will need to remove them.
  • Attach the filling loop to the system – make sure that it is properly in place and totally secure to avoid the chance of leaks.
  • When you are sure that the filling loop is firmly in place, you can open the valves. Once these are open, water will begin to flow steadily from the mains, into the main body of your heating system.
  • Take a moment to listen closely to the boiler – can you hear water beginning to wake up and flow? If this is not happening, there could be a more serious issue with the boiler – now is the time to call in the professionals.
  • If all is going according to plan, the dial on the pressure gauge will begin to steadily rise. Once it reaches 1, you have hit the ideal pressure. Take care not to repressurise – this can come with its own set of problems.
  • When the gauge hits 1, turn the valves on the loop back to their original position, and gently remove the filling loop from the boiler. You may encounter a few drops of water, but this is not usually an area for concern.
  • Once water has stopped dripping through, you will know that you have tightened the valves adequately. At this point, you can replace the end caps, if these needed to be removed.
  • Keep an eye out over the next few days, particularly when you fire up the heating or hot water. If your system loses pressure again, this can be a sign of a leak.
