Hi
I have a Worcester cdi rsf combi boiler, it is I'd say 8-10 years old. Today the heating didn't come on this morning. It has a little clock on the front, that has a dial with arrow pointing and a switch on it that goes from 0 to I. It is on I for clock on.
I am suspecting the clock to be faulty. But when fault-finding it seems a bit confusing. I have removed the mechanical clock from the boiler, removing the 4 wire links from it (with it turned off of course).
The is a permanent live and neutral connection to the M connections. And a switch connection between the other 2 terminals, 5 and 3.
When testing for continuity the meter always buzzes and shows 0 resistance. Which I am confused about, as surely that means it's OK? It seems to buzz and show 0 resistance on all settings
How does the clock work? I'd have thought it made continuity at the set times ie between 6 and 8 when the black clogs were set?
