Dear forum,
My boiler (HE36) has just been serviced following an intermittent L F error and had a new pcb (primary and secondary controllers) installed by the local reputable and popular engineer.
At first they put a new (orange) pcb in with the old face (not compatible I believe).
Then they added a new face plate but did not read the instructions and simply copied the old jumper settings. At that point it ran at 18kW.
I called them back and they read the instructions and set the jumpers to the right places.
It now only uses a maximum of 31kW of gas versus 41kW last year.
The gas pressure is okay, the jumpers in the correct places. It comes up with 2.2 code on start up so the controller really thinks its an HE 36.
This is the maximum it will run at (boiler thermostat as max and boiler fully cold).
Can anyone advise whether the boiler in simply knackered or point to a specific issue which might be rectified?
Do you think that inserting the pcb with wrong jumpers would damage the pcb?
Assuming the pcb is okay - what might cause the boiler to remain under powered (10kW lower compared to last year).
