I found this pressure washer on the side of the road, 3 years ago. Seems like a beast by weight. Plugged it in and discovered the switch was bad. Replaced it and the electric motor to came to life. So then it sat for like 3 years in my basement. I was messing around with it today and when I connect it to water and power the pump primes out of the clear tubing. When I flip the switch nothing really happens, nothing from the blue pressure hose. Oil is full. Slight brown tint but pretty clear. Issues The pump seems to be leaking where the pump meets the electric motor. The pressure meter is stuck on 1250psi. So is this something I can repair? Something cracked/seized/new seals? I am pretty good for DIY but any tips or quick things to check before I Spend a bunch of money would help. Or is this just a big paperweight?
