SOURCE: B302 - unable to start detergent flowing - How should it work?

It will only pick up detergent if you use a low pressure detergent nozzle - or no nozzle at all. It also takes a while for the detergent to get to the nozzle.

SOURCE: karcher washer went dead

Dear jimbocom,
The problem is that the spill valve got stuck. When the machine is working and the gun is closed, a valve( spill valve) moves with the accumilated pressure and switches the machine off. So what happened is that when the spill valve did its job, it found no water...and remained stuck. This leaving the machine in an off position. Service and lubrication to the spill valve must be done or completely replacing with a new spill valve. In my opinion you have no serious damage, but this job must be carried out by an expirienced technician.
Regards,
MG.

SOURCE: Karcher pressure washer won't start

Dear ralph_birtwi,
Most pressure washers when their gun is released, the machine stops automaticaly. This is done ny means of a control valve. When the gun is closed...pressure is built and the control valve moves and switches a micro switch off. In your case the micro switch is still closed in off position. Now this happens if a machine is left and stored with pressure in it., This control valve could get jammed and leaving the micro switch in off position. It could also stay in off position by sticking, due to incorrect chemical.
So the control valve or even called spill valve, must be renewed.
Sometimes a little lubrication with the right type of silicon grease will get the control valve working again. This job is sometimes delicate and better done by a qualified technician.
Regards,
fulltech.

Gun could be the problem if you hear the engine pick up speed and you can feel the pressure on the hose.if engine speed doesn't increase than there is a governor issue with the engine.

Karcher k3.00 lack of power


Are you using the same water supply as before when you had good pressure? Some house water lines have pressure reducers to protect your pipes and appliances. This can restrict the water flow and reduce the pressure the machine develops. If the flow surges (good, then weak, then good etc) you are not getting enough water to the pump. Try a larger diameter garden hose (5/8"). If you know where your water line enters the house, try the hose bib closest to it. Often times it is at street pressure instead of (reduced) house pressure.

Does not give a continous high pressure flow cuts in and out


that is sure signal of insufficient water supply!

try easy solution first:
make sure that your mains is fully open, that tap on whihc hose is hook up is fully open and hose is of "decent" diameter to allow sufficient flow.

if above solution do not work then you need to make another, more difficult arrangement:
prepare 20litres pressure tank with inlet connected to mains and outlet by short hose to power washer, fill it with water from mains, keep it under mains pressure and use karcher power washer normaly. this will solve water supply problem. twenty litres will last about 2min, because it is re-filled, under standard pressure therefore it will last about 3min...

third possibility is to stop washing...

if you find my advice helpfull, please do not hesitate to left the comment and vote for me, thanx!

Karcher K2.36 motor cut out and won't restart


Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.

No pressure HOSE IS BIG ENOUGH,NO KINKS, FILTER IS CLEAN. TOOK THE PUMP APART AND CHECKED ALL THE CHECKS, THEY WERE ALL OK.WHAT ELSE CAN I LOOK FOR? THE PUMP IS A KARCHER-MODEL G 1800 LB Thanks, Art


Brother Art,

Try this trick; it always works for me. Assemble the garden hose to the washer, install the HP hose, turn on the water. Now, make sure that there is no air trapped in the garden hose. Manipulate so as to direct any air trapped in the line to the washer. Connect the gun and continue to allow water to "free flow" for several minutes. Now, work the trigger, allowing the unit to rise to "house pressure, and then pull the trigger, dropping the pressure suddenly. This displaces any air hidden in the system. Do this several times, and start the washer up. If this doesn't get you up to pressure, repeat the above on an abbreviated scale, and hold the trigger on the gun down while you start the washer. This should do it.
Regards, --W/D--

I started working with the Karcher KB4040 pressure washer and all was well for 1-2mins, then it sputered a bit and all power died. All hoses were still attached properly, it hadn't blown a fuse in my house...


if the water is in anyway impeded, like kink in hose the unit turns off and goes into protection mode. That it it shuts down for a pewriod of time depending on how hot it may have got.
When its rested try it again ensuring you definitely have water flow.If the solenoid has failed it costs about !60-200 to fix as they replace all seals regardless

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.
