Karcher K2.36 Pressure Washer I've just fired up my Karcher for the first time since last year and the motor started running fine, I then switched on the tap to allow the water through and the motor cut out. Now it won't restart, any ideas? I'm wondering whether the water supply should have been on before I switched the motor on but it's too late now! Help!

My karcher hds 745 is running but just won't build up pressure, this occurred after a really cold few weeks this winter and I hadn't put anti-freeze through the machine to winterize it. There's no water coming from the bottom of the machine when it's running as i've read that if the pump seals are faulty water will escape from the pump etc. The machine motor runs ok but no pressure is acheived on the gauge whatsoever. Any help would be appreciated. Thanks in advance Paul.

My karcher k2.20 motor keeps running even when i release trigger and water is pouring out from inside the casing....

You need to get the casing out of your way so you can see exactly where the water is coming from. Best guess, just starting out, is that the pump has an "Easy-Start" valve on it that is not closing. This Easy-Start device is just a small valve that ... Karcher Pressure Washers

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.
