Dear mike husband,
One reasin for this fault could be a damaged lance or turbo lance. Try by replacing with new ones. If the problem is not solved, then the fault is due to a damaged spill valve. The spill valve could easily be damaged by using not suitable chemical or detergents. After using chemical detergents, one must always rinse the machine by passing pure water. The spill valve could also be damaged by leaving the machine for a long time with pressure in the system. One must never store such machines with pressure still inside. Always press the gun before storing.
Well the solution is to change the spill valve with a new one. In some cases even faulty suction valves can give this problem. But in the majority of cases it is the spill valve.
If you do not know how to fix this problem, it is better to be done by an expirienced technician.
Regards,
MG.

I have an electric power washer k3.99M. I just replaced the pressure hose and now the washer will not turn on. If I remove the unit from the water hose, it works, but when I hook everything back up, it...


This sounds like the hose is plugged or the nozzle itself is plugged. If the water cannot get through, the washer senses that the trigger is off and will not turn on the pressure. First just attach the hose without the gun and nozzle. If it pumps water, you know the hose is OK. Then attach the hose and gun ant try it. If it still works then you know it is the nozzle.

Karcher Power Washer that surges up and down with water pressure.


Before you start it up:
1. Disconnect the high pressure hose 2. Connect the water supply and turn on 3. Make sure water is flowing through the pump
Start the motor, run for about 10 seconds and then turn off.
Turn off the water supply, connect the high pressure hose, turn water back on, start the motor and away you go.

Dear Pajodi,
I just came across your problem. I have just joined FIXYA, and solved various Karcher problems. First of all with all respect, the shop from where you bought the machine, must have told you all necessary instructions to operate your machine.
Now the soap always works on low pressure. So if you have a variable lance, turn it to low pressure. You can also remove the lance, and the soap will surely starts to work. With turbo lances, the soap system does not work. This concludes that the soap does not work when high pressure is used. Bigger machines do spray soap at high and low pressures. But these have regulating knobs, to swith off and on, the soap supply.

MG.
