Thanks again for your advice :D

Your help is much appreciated, i had a bit of a panic on, christmas in Cumbria with no CH not a good mix :D , just one last question, is there any manufacturer you would recommend to use with regards to buying the timer/programme box??

Thanks ratonnastick, are the timers easy to fit is it worth changing manufacturer or is the Landis & Gyr quite reliable?? Also is it something i need to do straight away?? or can i keep the test loop in between pin's 3 & 4 just while i'm in the house to keep it warm, the boiler runs just like...

Just somthing i've thought there in regards to the timer control, it's a Landis & Gyr RWB100 i'm sure when it was switched on & everything working that there use to be a red L.E.D in the bottom right corner as your looking at it, i just realised tonight after doing the 3 & 4 pin test that the...

Hi which micro switch is it the top red one?? ive pressed that in but it doesnt make a difference the boiler just doesn't fire up :( when trying to use the CH. I cant see any leaks it had a one a while ago which has since stopped it seemed to be coming out of the auto air bleeder at the top &...

All i can see on the diverter valve is the top & bottom (red) micro switches with a plastic cover over them, it is at the lower right as you look at the boiler, the switches are pressed by 2 pins on a plate which moves to the right as the DHW is switched on, the DHW pin being the lower spring...

Sorry i worded that wrong i'm not sure how old the boiler is i should of said its at least 10 year old as there is a label inside saying it had some additive put in it in 2001 & not to drain so i kind of guessed the age off that :oops: , however i can't afford a new one at the moment & a lot of...
