Question: Shut Off

tomnjo

My pressure washer cycles on and off when the trigger is off. The motor is supposed to stop when you stop spraying and come on again when you start. Can't figure it out. No leaks anywhere. I've been into the pump many times and still don't completely understand all the features.
Wally
Question: On/off Switch

Wally

I have two K 3.99M pressure washers. Water is supplied and passes through the spray wand. #1, with power supplied, the manual switch will not start the pressure pump, and pops the GFCI. #2, with power supplied, the manual switch will not stop the pressure pump, nor will the pressure build up to stop it. Do I need 2 manual switches and at least 1 pressure cutoff switch? What are the part numbers? Thanks, Wally

Question: No Spray

Lynn K

My Karcher k 3.99 washer stopped spraying. There is weak spray from the gun. The motor doesn't come on and the hose pressure stays low.
