Karcher 211 - no motor action

\015 Hi all\015\012i have a Karcher 211 pressure washer, it was working fine then when unplugged and put onto a different tap the motor stopped working. Water comes out when you press the nozzle thing so its not a blockage there, have checked the fuse (its not that). Any ideas? Its hard to get to the motor because of the way the casing is put together. Any suggestions welcomed!!\015\012Thanks\015

Dear Tigger82 (also montaver2000),
\015\012This explaination is relavent to various Karcher models, especialy your model. When you are using the machine with the gun open....presurised water comes out of the lance. When you close the gun, the machine stops. This happens by means of a Spill Valve or often called the Control Valve. When the gun is closed, this spill valve cotracts with built up pressure and at the same time works on a miro switch which cuts the electricity....and thus stops the electric motor. Now in many cases when the gun is again opened, this spill valve sticks and keeps the electric circuit closed.
\015\012In all cases you must open the cover, and locate this spill valve. Sometimes it is easy to see a micro switch on it. If you remove the miro switch from the spill valve the motor will for sure turn.
\015\012Now the spill valve gets stuck for many reasons. One of the reasons is that you leave the machine under pressure for a long time and even store away the machine with pressure still in the system. A spill valve also gets stuck due to detergent. I sometimes service the spill valve and lubricate with special solicon grease. But the best way is to change the spill valve with a new one. So in a few words, the spill valve is stuck and leaving the microswitch off. So the electric motor cannot turn. One final hint is that sometimes the spill valve is difficult to remove. So all one has to do is attach water supply and switch on the pump. With the pressure produced the spill valve will be pushed out. In my oponion this job must be done by a person who knows what he is doing. Carefull that you have safety electrical breakers. See that you have safety shoes, safety gloves and eye protection.
Did you plug it into a higher voltage outlet.

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.
