Vaillant boiler error code F75 urgent help needed

[mdea]

Hi Staffs,
I am having problems with Eco Tec 824 boiler (see mdea posting) I had Vaillant out to fix boiler which is constantly breaking down due to F75 error and sensor but he said that there isn't a known fault on this model despite the fact that they changed the position of the sensor on later models. I am interested to hear that there is a repair kit. How come they don't know anything about it. Are they trying to pull the wool over my non technical eyes. Cheers mda

They put the sensor in the wrong place and now with f75 there is a f75 repair kit part no 0020023721 I know you will have sorted yours but this may help others

HI,

I have the same problem with my boiler and when spoke to their technical department they recommend the F75 repair kit. I understand that the repair kit cost is around £140, can somebody tell me how much will/should a plumber charge to install the repair kit.
