Yes, with the cold off only c appears. It does seem to be working now... Since shutting off the cold first time round then opening it up again. Tho the blue light keeps flashing and the boiler clicks on and off. Should it be doing this? I guess it should click on and off - but the blue light...
Oh dear!! Well... Since the above the the boiler is now heating the ch for 30 seconds before returning to fault d flashing. Consequently the house is warm for the first time in 3 days! Inbetween flashing d faults it goes to a fault c, which seems to kick start it. Any ideas??!!
Brilliant! Thankyou for your advice... Did as you said and sure enough, the d dissappears and turns to a c. Also just found the isar fault webpage and it shows that I need to get the leak fixed! Thanks again!!
No hot tap dripping no... But I do have a minor leak in the ch system - literally a drip or two per hour. My plumber is going to come out and fix this. Will that fix my problem?? Thanks for your help.
Hi All,
I've got a ISAR HE24 combi and though it heats the hot water fine, the CH isn't working! The blue light is flashing so I'm guessing that it's not igniting?? Can anyone point me in the right direction of a fix or is more info needed??
Having read all previous posts I'm wondering...
