Topic: Ideal Sprint RS75

Hope someone can help.

Got an old Ideal combi which was working fine. Just had to move a rad, so turned off boiler, drained down, fitted rad, pressured up, bled air out and turned back on.

Now, although the pilot light is alight, and the led's are on on the main panel, there is no DHW or heating. When heating is selected, pump runs.

i've gone through fault guide, told me to replace PCB driver board. (80 quid) still the same
Can someone offer any ideas?

Many thanks
