Boiler error E133

[Adrian rowlands]

Hi we purchased a property ag christmas and had no issues over winter however my boiler has currently stopped working and displays the errors code E133 which is gas supply error, I've tried resetting it with no success, ive checked the pressure and it's fine and then main gas valve is open but had no luck with getting it working again

Boiler model - Potterton promax Combi 28 HE A

Anh advice would be appreciated

A very common fault on that boiler, unfortunately we cant give advice as to what it is as it is against site rules , you need an RGI to change the part that is faulty, the new part is much more robust and reliable
