Re: ariston evolution code f08
As most of these problems are due to burnt contacts from the amount of current the heater draws through them, have any of you lads ever considered changing the heater relay on the board, rather than the complete module. These relays are dirt cheap from places like CPC. All you need is a solder sucker and iron and it takes a few minutes to do. No doubt the customer will be well impressed with your expertise, and not to mention the cash you will save them.
Re: ariston evolution code f08
I’ve come across this problem on EVO 2 equipped machines, in most of the ones I’ve dealt with, (if it’s an IDC machine, that is, thin wires to everything), the problem is usually down to wiring and crimp joints. On the non IDC (thick wires to everything), the problem is usually either the thermistor or a board fault.
