Karcher - motor still runs if handle released

Mar 29, 2010 4 Replies

Surprisingly the Karcher pressure washer survived the winter in the wet garage.



On turning it on the motor pulsed on/off about 3 times and remained fine - but the motor does not turn off with the handle, the motor runs continually.



Anything obvious to start with?


Pressure switch is buggered, prolly frost damage. Which model?

Karcher 432M Super.

I take it the pressure switch is in the main body, not the lance?

Correct. Page 26 here.

be the clip (5) has come out.

That does sound quite likely. I knew I should have taken the "hoop" & hose off and stuck the body under the stairs for the winter :-)

Many thanks for taking the time.
