I have a Karcher 211 pressure washer. It has started to switch itself on and off continually in standby mode instead of staying off while not actually jet washing.The pressure valve to operate the electrics just keeps moving back and forward. Any ideas ? Also been on the karcher site but cant find any technical diagrams of the internal workings ?

I'll wager the plastic pump head has a crack in it...either that or the bit that connects to the delivery lance.
