Hello
Have been battling with this issue for a while now.
Icos HE15 starting firing up by itself every 6 to 7 minutes for about 20 seconds then would switch off. The only way to stop this was to actually switch the boiler off.
Boiler would always switch on normally for central heating in the evenings.
After much research most likely problem seemed to be a stuck micro-switch in the Drayton ZA5 actuator (2 port) so I have just fitted a new one.
The valve is not stuck and can be turned by hand.
Now, the boiler won't fire up. I switch on and the boiler code goes from 0 to 2 and back to 0 and then just stays there.
Anyone any ideas please, this is driving me nuts!
Thanks
Neil
