Boiler timer, clock not functioning 'Sime format 80he'?

Have had same problem for a couple of months now.
Model is Sime Friendly E.
Plumber has changed clock motor twice so problem lies elsewhere. power is routed from circuit board through a cylindrical component on far left-hand-side - looks like a switching relay but circuit diagram is not in standard electrical symbols.

How many visits does it take from a plumber before it is more cost effective to just replace the boiler with a more reliable model from a reliable manufacturer? not many, I guess!

Did you find out how to check it is correctly connected as I also have this void of knowledge?
