Re: pressure washer karcher
Sounds as simple a fix as " The Fuse Has Blown "
Check the fuse in the plug, and it,s Rating.
I,d assume this should be rated at 13 AMPs.
If the fuse is 3-5 amps it,s under-rated.
You should get it tested out if your not electrical minded, you may have a short circuit. live/earth et.c.
hope this helps.

Make sure that your circuit breaker did not go off and you have power..
Turn on the water after connecting the hoses. Then connect an ohm meter to the hot and ground legs of the male power plug. Push the on/off button to on and then pull the trigger. When you do that your ohm meter should indicate the resistance of the motor windings. If the resistance still stays at zero, then 1 - your motor is burnt out, 2 - the on/off switch is not working, 3 - the water pressure switch is electrically open. Check all three for proper operation and replace as needed.
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 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.
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.
Depending on the model of the machine, it is most likley a cracked control head or split outlet elbow. Remove the covers and run the machine to locate the source of the leak. Ifit is the control head it will spray water from the top just behind the chemical inlet elbow.
