Need replacement solenoid for JC Shampoo Vac

Thanks for the information. I took the whole panel off so that I could access it and tried grabbing the stem and twisting it with pliers, but was afraid to break it and stopped. I figured if I buy another, I could swap it then try to fix this one and keep it as a spare. There are two notches right where it screws in. Are you putting a screwdriver there and knocking it loose? Also, any particular solenoid that you recommend as a replacement for the just a 2 way? Not sure which ones would have the threads to screw back into the panel so it's not hanging there. Thanks.
 
You wont get it apart by turning the stem. After you take the coil off you will see 2 small holes in the ring around the stem, if you can a screwdriver or long ceter punch and hammer them in a counter clockwise direction that ring unscrews. Kleenrite has a rebuild kit for that. Its not simple but much easier then taking apart the whole machine.

You might have damaged the stem with pliers. If you get it apart, make sure the plunger moves freely inside it.

Yes, once you get the retainer ring turned a little with a hammer and screwdriver you should be able to twist the stem by hand while pushing on the ring and unscrew it.

The solenoid you linked will work. The only difference is the coil isn't under a chromed cover. All the GC solenoids have tapped holes in the bottom.
 
Thanks for all the information. I did order one that was the same price but had the chromed cover. I will try to loosen it using the methods you guys described before switching it out. It still seems to work other than a constant slow leak when the hose is below tank level, so hopefully no issues with the plunger. I found small debris in the shampoo line right at the head last week and had to clean it out, so I'm hopeful that there is just debris under the plunger.

Sometimes the push button switch goes bad and shorts out. That would cause the problem you describe. Do you hear a solenoid clicking when you push the shampoo button?
 
Solenoid does click. I've had the button go out several times over the years, so that's the first thing I look for. First time I've had to mess with a solenoid in 5 years. I'm pretty sure it's just debris.
