Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
There are only two things that would cause this. Either the machine is not dropping to low pressure or the chemical injector valve is stuck.
Taking a look at the troubleshooting guide there are other obvious problems. I have listed all possible problems here.
Detergent suction tube not properly connected to the machine.
Detergent is too thick.
Filter on detergent suction tube is clogged.
Damaged or clogged detergent suction tube.
Quattro Nozzle is in high pressure position.
Discharge nozzle is obstructed.
Most of these are obvious problems that you have most likely already checked or would have noticed.
