Turn water on then actuate wand trigger. Pressure washer leaks when wand trigger is actuated and has very low pressure/flow output. After releasing trigger the pressure cycles on - off at approx 1 second interval. I suspect that the plasstic oulet tube is leaking causing low pressure leak out of bottom when trigger is actuated and causes pressure switch to cycle when the trigger is released. Any Help? This pressure washer is approx 18 months old!

We have a Karcher G2500VH pressure washer. If you start the engine with the trigger pulled on the spray wand it will run at full pressure until you release the trigger. after that, when you pull the trigger it will not have any more pressure than the water hose feeding it.

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

I have a KARCHER Model K 2401 which onstart up has normal water pressure rather than the high. I can usually get it to work by removing the tip, pressing the trigger and running some water through without the tip on. The i replace tip and it will usually retain the high pressure. If I stop depressing the trigger I have to go through these same steps. It is like it loses prime. It works well once I get it started putting out the high pressure.

The motor keeps cycling on and off (about twice every second) when the pressure trigger is not operated. The unit seems to supply plenty of water pressure when trigger is operated.
