Error code e10 on boiler

E10 showing as a error on the boiler generally means low or no boiler pressure. My advice is if your confident to do so top up the boiler pressure (from the filler loop) to the correct working pressure. At this point the boiler should start to try and fire up. Then leave heating on for at least twenty minutes and check for leaks or cold spots in the radiators. Take care

if you are not boiler engineers, you can't touch the boiler, including filing loop

hi, pressure drop .. Adding water to the system to increase the pressure will bring it up to the required level. needs to be above 1.5 if unsure post job on my builder . thks.
