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.

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!!
if your leak is on your heating system that isnt causeing the blr to go to d.
the test you have just proved is you have a leak on your htw domestic pipework or a driping tap.
sorry to be a killjoy

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??!!
'd' and 'c' are NOT fault codes.
'd' is telling you the boiler is in dhw mode and 'c' that it is responding to a call for heat from the heating controls.
You have a drip or leak on your HW pipe work it seems.
With the cold isolated under the boiler, it should remain on 'c' all the time the heating is on, apart from possibly going to 't' occasionally.
Other than this you should see '0' if there is no demand from anything.

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 usually only flashes when its going wrong!! Sorry to pester!
like dave said.. d is for domestic htw c is call for heat from external controls an t is for pre heat when the wtr in the plate drops below 30 degrees. so by turning off the isolation vlv on the cold in will stop the blr showing d & it should stay on c t or 0 this will prove you have a leak on your htw pipework etc.
