I've inherited this boiler from the previous occupants, I've downloaded the isntructions and it seems to be doing its job ok. But... the display keeps flashing. It's usually flashing "0.3", but sometimes "0.0". The LED above the reset key is not on or flashing, and the two codes do not resemble the fault codes listed in the manual.
So, do I ignore these flashing numbers or do they need dealing with?
Thanks!
