Starts fine, but when you pull the handle on the spray wand, the pump does not kick in and the water just continues to trickle out of the end of the wand at regular faucet pressure. Occasionally the "clutch" will kick in and you have full pressure, but if it does and I let off of the trigger then chances are that it won't kick in again. has been getting worse for several years.

I have had 3 Karcher pressure washers all experience the same problem and so have two of my neighbors. Our area has very hard water and it causes problems with the washer not bringing up the pressure when the trigger is pulled (or surges up and down) and the nozzles clogging, etc. The service repair facilities cannot tell me how to prevent this.

Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output.
