I have a main eco combi boiler.My timer is Grasslin FM1 .There is on off and timer switch.Recently my timer stopped working.If I turned it on off manually the boiler was working fine.If I bring the switch to the clock , nothing works.So I thought I have a problem with the timer bought a new one from ebay.I put the brown wire on number 1, blue on 2 and the 2 black on 3 and 4.The new timer has 5 as well.Again if I turn it on off manually it is working but the timer is not.I have spent £28 on the timer and nothing has changed please help!
