Hi guys I also checked the problem of the valve antiscuotimento of my 159 I have decided to make it exclude electronically (no one has done anything to the valve right?nn the has mechanically locked... ) after that I did the work yesterday while I was walking to me. Check again the error I switch off I switch on the machine and everything returns to appost(removal from the unit and was made yesterday, after that episode no problem, as. Me. See if the valve and blocked really?
