The hose beats the ground until it bursts while washing. I noticed the water supply hose was leaking a bunch due to no hose washer. Could this cause the pump to **** in air and cavitate. I replaced the hose washer so I had no leaks and it was still bouncing the hose. Could a faulty soap suction valve do this??

Hi, when the hose shakes badly it is normal down to dirt in the valves.
please check them first
Its possible that while you were using it without the seal in the inlet fitting that you may have worn the pump suction seals or cracked a ceramic piston due to cavitation, do you have any leaks under the pump when the water is turned on and the machine is running?
If no leaks it could be a check valve that has a bit of dirt in it. remove valves on pump head and inspect them. There are usually six valves on the machine , three inlet and three high pressure.
if its one of those petrol engine machines with a copy honda engine, well good luck to you. they're not designed to last and have seen them destroy pumps in next to no time. cheap and cheerful.
If it is one of these machines then its probably a valve spring that has broken making it pulse because it isn't opening and closing the valve. put a different spring in it and it should be good to go.
It sounds like your nozzle is plugged or partially plugged or the wrong size

I fixed it by cleanind a bit of silt from the pump valves.
