Ideal Response 120 boiler fault?

check low water pressure switch ? a= they can weep / leak on to overheatstat thus causing fuse to blow. b= low water pressure switch could also be blocked with sludge thus preventing closed electrical circuit

Hi Ady,
I've just had a very similar problem with our Response 120 this morning. The fuse had blown, and when I replaced it it only ran for 15mins before blowing again. Against my better judgement I tried another fuse and this one blew as soon as it made contact. Did you get anwhere with fixing your problem?
Other searches have turned up lots of problems for this boiler model, but yours was the first mention of the fuse blowing.

Does anyone else have any suggestions? I'll go through the MI later today to see if that sheds any light on the matter.

Cheers,
Dan
