I'm having a problem with my Vokera Linea 735 boiler that I hope someone on the forum can help with.
The boiler is losing pressure until it triggers the 04 fault code, however, the pressure loss only happens when a hot water tap is opened.
I can have the central heating on for a couple of hours and the pressure is fine, however, as soon as a hot water tap is turned on the boiler pressure starts to drop and if the tap is left on the fault code appears after about 5 mins.
There are no evident leaks in the boiler when this happens.
Any help on this is much appreciated!!
