When my washer is not engaged and flowing water and is just sitting on the trailer idling while I spray chemical its making a "surging" sound. Like it revs up and down and up and down, but when I flow water it's smooth and has plenty or pressure and GPM. I'm leaning towards the motor because it doesn't do it while flowing water and I would think if it was the pump it would do it all the time. I've never really worked on the internal parts of a pump myself, I've been in business 6 years and do normal maintenance my own but never replaced rings or plungers or anything.
Any ideas or got a number I can send a video of it doing it too?
