Hello
My Ideal FF260 has been boiling the water in the hot water loop recently, it does it every month or so, and the rest of the time it works perfectly. Today I removed the PCB and found black carbon deposits inside the clear housing of one of the relays so I am going to change that since I think it could be sticking closed and causing the problem.
I also want to change the thermistor, but it wont come out of its hole in the front of the heat exchanger block, I suspect that it has glued itself in due to a small amount of white paste on and around it. It is either a Boss white type sealant, or it is a thermal paste which has gone hard. I have already removed the metal locking cover disc by the way.
I have tried pulling and jiggling on the cable, I have tried a bit of WD40 down to hole to soften the paste, and I have tried pushing a bit of copper wire down the side of the cable to try to break the adhesion. Nothing will budge it.
Does anyone have a good trick for getting it out of its hole?
Lastly, is this a blind hole? I think it must be but I am not 100% sure. If it is, and push comes to shove could I give the thermistor a good hard pull with pliers and if it breaks can I then use a drill bit to clean the remnants out of the hole. Or will I risk getting bits of crud inside the heat exchanger?
Thanks
Chris
