my potterton boiler is only 3 months old and i am getting a e168 message, how is this fixable?

I understand that E164 is water pressure problem due to clogged filter.

E168 is a faulty PCB that needs to be replaced - well over 100 pounds

I think this error code relates to low water pressure in the boiler - check your user manual. If so then open the 'filling loop' to inject some water in - close it off when boiler pressure guage comes to 1 bar. easy eh?
if that doesnt fix it then the water pressure switcvh inside will need replacing
