pressure control valves are non adjustable
They operate to unload the pump when the trigger is released
What can vary pressure is the jet size at the end of the wand
The screw and nut on the valve is only to regulate the stop/start pressure as the trigger is pressed/ released
low pressure at the wand jet can be from low water supply to the pump or pump internal problems
It is a water inlet problem, perhaps pressure too low, or restriction in valve, check the valve filters by turning off supply to washer, and checking the filters in the valves.
Low water pressure from source is generally not a problem unless water hose to washer collapses when use. You only need to supply the pump just 3 to 5 gallons of water per minute. Easy to check. Just open water supply to hose and capture water flowing out of hose into 5 gallon bucket (capture water in bucket for 1 min., should pretty much fill it ). Just use as normal. Good luck
TAKE TUBE OFF JETS AND TRY IF WATER FLOODS OUT THE THE PIPE, JETS ARE BLOCKED, CLEAN OR CHANGE, IF NO WATER TO THE JET END OF PIPES CHECK INSIDE THE BOTTLE FOR DIRT, IF THAT'S CLEAR, THE THE MOTOR IS SPINNING BUT BUSTED INSIDE
Dear Osville,
It is not clear what type of lance or nozzel you have. You said that the machine works fine with the circulating water jet(the turbo). So it seems the machine is fine. I do sometimes service variable nozzels and variable lances. But the best solution is to replace nozzels and variable nozzles and lances with new ones. Regarding the fan spray setting it could have no pressure because it might be in the chemical setting. The chemical setting lets out a fan shape flow of water, but with less pressure. The chemical system only works on low pressure in domestic washers, that is why it needs a low pressure flat spray. The pencil jet has 2 jets comming out because if it is a lance or nozzel with ball bearings, these ball bearings must have stuck in a wrong position. Also 2 jets can come out, due to a damaged nozzel hole.
Altogether, the best advice is to buy a new nozzel or lance...which ever your machine uses. All Karcher machines have their own specific nozzels, lances and high pressure hoses. You cannot change these from one model to another.
Regards,
Fulltech.
Get yourself a small gauge/thin piece of wire. Poke the jet holes with the wire until they spray like they used to. If you have an air compressor you can also blow through the sprayer with compressed air after poking them with the wire and they should be good as new. If that doesn't work you might have a blockage in the line at the one-way valve or at the pump in the washer tank.
