hi,ive just been for a look at my mates eco max not sure what kw but he has been complaining of eccessive noise when he has the bath running etc and has to turn it off, there is no fault code present,im not good at the diagnosis side but i did notice that his hot water temp on the boiler was going up over 70 deg C (not normal) and thats when it starts to make that unpleasent vibrating noise,the heating was on at the time when i tried it, it wasnt up full though so not sure if its the same on the heating side,just wondered if any one here has came accross this problem before as i would be gratefull of your help, andrew
