Truma CP plus lost icons on control panel. (1 Viewer)

[SteveE72]

Unfortunately that won’t work for me, as bpitas I don’t seem to have any power at the boiler, I have no errors or icons on the control panel either. Thanks anyway.

I have a new Truma 2e pcb panel, I bought in error and I cant see any reset switch on it either. If anyone wants it they can have it cheap as it's just sat there.

SteveE72 Have you checked the combi power supply fuse at your PSU.

Yes I have

Yes I have

The 12V fuse on the accessible part of the circuit board is another candidate. Have you checked it with a meter to see if there is 12V on both sides of the fuse? If there is 0V on both sides the fault will possibly lie in the circuits leading to the boiler.

As Allanm says the top row of icons disappears when everything is off but you should be able to select from the lower row as shown in his pictures. However I had a similar problem as your friend when my unit was new. The fault was simply that the rotary control knob had slipped too far down the shaft of the controller and this was stopping the push function from selecting anything. Having pulled the knob off the shaft I found all the functions returned to normal, I then put the knob back carefully making sure it was not too far down the shaft. If I push the button too hard it sometimes repeats the problem, I have learned to live with it.

Great to find information on older threads.
This has sorted the "getting less and less responsive" button on mine.
It was getting quite frustrating but now all good.
Thanks.
