Mike I think you are correct
It stopped working in five min,
Any suggestions why this happens
I can imagine getting an incorrect part from the factory but it seems like this is what happened
It worked for five then just quit???
Hi Ken,
That is a demand/delivery pump. This means that when you stop spraying, the pump pressurizes the plumbing. The pressure switch, located on the pump head, senses the increased pressure and shuts the pump motor off. When you relieve pressure by spraying or creating an open orifice, the pressure drops. The pressure switch senses the drop in pressure and allows power to flow back to the motor. Unless it was wired incorrectly, it should still work and can be trouble shot fairly easily.
The following will give you a basic understanding of your plumbing and some things to try:
-When you turn the pump switch to the on position, the pump immediately pressurizes. It may turn on for a second if there is air in the system (from installation) but it will shut off as soon as the lines are pressurized. In normal operating conditions with no leaks/air in the system, the pump motor will not turn on because the line is pressurized from your previous job. It won't deliver spray until you demand it.
- The Polaris has two ways to demand spray. The line coming from the "OUT" port on your pump head forms a "T" of sorts. On one side of the T, you have the solenoid which allows water to flow to the tips. On the other side, you have a quick disconnect, used for carpet wands, upholstery tools etc.
- The solenoid is an electronic gate valve that is activated by the activator/momentary switches located on the handle by your thumbs. The solenoid sits between the pump and the spray tips. If you push the activator switches, you may hear a "click" sound. This means power is going to the solenoid. Under normal conditions, it should open and you should have spray. It seems you are not getting either to happen, you may have a clog or a dead solenoid. You may even have a working solenoid but the tips are clogged. Do the next step to narrow down the possibilities.
-The Q.D. is located on the back of the machine, rear bottom left. If it's a male, take the handle of a screwdriver and push in the spring loaded nipple in the center. This will open the Q.D. and allow water to flow. If it is a female Q.D., take a male Q.D. from one of your tools and insert into the female. If there is no clog, water should flow freely and your pump motor should turn on. I should warn you to be in a place where you can spill water and also to cover the Q.D. with your free hand to avoid being sprayed in the face. If it sprays, your pump is fine and the problem is at the solenoid (clogged or dead), spray tips, or the switch that activates it. Again, if you hear a click, the switch is fine, the problem is the solenoid (or tips).
Try that out. I'll look into a good pump housing on a scrap unit here.
Thanks!
