namsag. I think I´ll get one and hook it up - although I can´t tell whether the clock is connected to the faulty timer. Thanks for the tip as well to look for a pump failure. If this does not work I guess I will check if the clock is at fault as well and check the 240V.
Thank you.

Combi boiler Potterton Midas , Myson BF ( 1993 - ALAH336).
Problem,
HW works ok, but CH does not. Pilot is lit up but main burner does not light.
Observations:
- Programmer´s internal battery is gone. I disconnected the prog.
- The pilot light ( should be on all the time)...
