Question about Karcher 1750 psi Electric Pressure Washer

2 Answers

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 and the fuse in the plug of the washer is working fine.When I switch it on I get nothing. Do you think the motor has packed in? I borrowed the machine from my neighbour who's away on holiday, so don't know much about age of the machine. Any advice much appreciated.

    Thank you so much nettiser. I went back to the machine, set it all up again, ensured all hoses were attached properly and it worked perfectly.
    I'd never heard of the protection mode but I guess that's what happened.
    Many thanks.

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

What's wrong when you only get full pressure for the first few seconds and then it stops and won't spray fully anymore?


Air pockets in the supply hose or the supply is feeding the power washer too slowly.

These things can really put out quite a bit of water, so make sure you've got a good supply going to it. No kinks in the hose, spigot opened all the way, etc.

If the problem is air pockets, make sure you're running the feed hose long enough to get a good flow of water before hooking up to and starting the power washer.

I can use my Karcher K3 jet wash as long as i hold trigger down


Most pressure washers have ball lock type fittings on the hose connections. What happens is the little steel balls get a bit of corrosion and do not lock the male fitting properly with the female coupling. Load up the fitting with some Oil or WD 40. Then connect and disconnect the fitting several times to losen up the balls and springs. Should the spring in the coupling break you will get the exact symptom your describing.

If the OIL / WD 40 does not do the trick then you may have to change out the quick disconnect coupling.

The motor keeps surging


If there's a lot of sediment in your water supply, there's a chance that sediment has gummed up the pressure switches. I'm assuming it has a full power switch and high power switch. It runs on full power until a pressure switch is satisfied, and runs on low power to slowly build the pressure back up, at which a second switch is satisfied from the pressure and turns the motor off. These things are not easy to work on, and are made of metal probably too fragile to try any chemicals. You should probably contact the manufacturer.

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.
