How to re-pressurize potterton promax combi he plus


I have a potterton promax combi he plus boiler. I woke up this morning and had no hot water. Checked the boiler and it says Error 119. I researched online and in the manual but the pictures in manual and others online did not look like the set up I have. Thanks!

If you need to re-pressure your Potterton Promax combi he plus boiler this means you are getting E1 error code
There should be 2 black valve under your boiler one on the left turn it left then one on the right turn to right you will then hear water passing true it , watch the gage until it gets 1.5 bar then turn the both valve back to original state
