Has someone been messing about with the PCB? This usually means the jumpers have been fitted wrong.
No-ones been messing with it - I just got up in the morning and no hot water. The boiler is about 3years old I think and serviced after 1st and 2nd year. Someone said could be the fuse?

Hi
The CH is not working either, it's definately H5 or HS.

either the jumpers are on wrong or it's a pcb fault. check the polarity too
If the fuse had gone there wouldn't be anything on the display, boiler would be dead.
Our boiler was fitted new 13 month ago and was recently checked by the company that fitted it. However, the pressure was lower than I thought it should have been, way less than 1 bar and this morning we had problems with H5 fault code flashing. (Can't understand why the service man didn't spot the low pressure last month, mind you he appeared more interested in listening to the radio than checking the boiler.) Nothing in the manual about H5 so I re pressured the system to the approved setting (I did this every couple of years on our old boiler). After a restart everything OK up to now.
