Hi All learned friends, I have a Stihl RE 530W Steam/hot water pressure washer which is not working. If I hold in the trip switch on the contactor it will operate and pressurize but will not fire, there is no smoke, so I presume it is not injecting(the filter is clean).I have the manufactures handbook,but don`t find it very helpful so was hoping that someone could enlighten me as what to look for(it has diesel in it)

Merry xmas to all.
