What causes funny idle with a rigid 3000 psi pressure washer

SOURCE: Ryobi 3000 psi pressure washer detergent injector

Most detergent injectors work by the venturi system. That is that the detergent is drawn into the stream by the forward flow of the water thru a very narrow port after the water passes thru the pump. This system works best when the pressure at the tip of the wand is low. Trying using a very large tip to draw in and apply the detergent, then remove injector and rinse with high pressure. Not good for the pump but to apply soap reliably under high pressure the soap needs to be injected through the intake of the pump. enjoy

Best to use NON DETERGENT 10W30. Be sure you fill the reservoir only 1/3 to less than 1/2 full.

What fluid and how much is required in the Troy-Bilt 2550 power washer pump?

I have a Troybilt Model 2200 PSI Pressure Washer in which I have used only 2 times in the past 2 1/2 years. Went to use it this past weekend and the pump in not working. Water shoots out of the side. I bought this brand and model as I thought Troybilt was suppose to be so good. Went back to where it was purchased and had no success but to say I could buy another pump or take it in to be repaired. I believe that this power washer should be replaced at no charge. 2 uses does not constitute a few hundreds of dollars.
Have you to heard anything concerning pump problems on this particular model? Thanks for any advice. .
