Pressure Washer 580.752000 Won't suck up soap.

by Manage My Life Last activity date:
March 27th, 2012

My pressure washer, Sears Craftsman #580.752000 no longer sucks the soap up in low pressure mode. I admit to not using it very often - once or twice a year. Last time I used it 6 months ago it would not suck the soap out of the chemicals bottle. Checked to be sure hose was not clogged: Both were fine. Also sure it was on low pressure: it was. Model is probably 5 years old, but been used less than 50 hours total. Want to do some "spring cleaning" but need to fix the chemical supply problem first. Thanks!

After I made my post, I see that you've already taken care of this problem. I'm glad you were able to get this worked out. Usually it's just a matter of the check ball being stuck and cleaning up the ball/spring will take care of the situation.




If you run into any other problems with it, please stop back by and let us know.

Where the chemical injection (soap) hose connects, you can remove the check valve there. Remove the port, spring, and check ball which is essentially the injection valve. You will most likely need to clean those pieces up with something like CLR cleaner or something that will take care of the calcium/lime/rust that tends to build up on that area.

Once those pieces are cleaned up then the pump should pull soap when on low pressure. If it does not then you will need to replace the pieces. As the spring weakens it will work correctly. If you find you need to replace the parts then you can go

HERE

and order kit number 190593GS for the replacement.

Thank you for using Manage My Life!

The # 199195 above was right on. The little ball had become stuck to the rubber washer that's also in there: Was able to bend a pin enough to poke it out from the back (so as not to damage the washer), clean it all out and tested it: Works fine now.
Thanks for the quick response - I really didn't expect an answer for a few days (which would have been just fine). Bruce
