Kohler Spray not working

I have a Kohler kitchen faucet with spray (K-10416). When the spray is used the water continues out of the spout (some does go to the spray). I replaced the diverter (GP75878). The water still does not divert to the spray and now there is a lot of vibration. I figured it was the diverting valve but this did not correct the problem.

It is possible the spray head is clogged Clean or replace.

I agree with Bones, it looks like the spray head or the line is clogged, disconnect the sprayer head try and see if you have good flow if you do the head is clogged clean or replace it, if no flow remove the line clean or replace, see the link below, if this would not help please get back to us,Thanks.

When you had the diverter valve (see picture) out.. did you pulse the water on to remove any sediment in the faucet itself?

Start by disassembling the spray head (see pic.) and then turn the water flow on... any water when you turn the faucet on now? If not, then back to the diverter valve.. remove it, pulse the water on/off until water flows cleanly through the diverter port and then reassemble. If water flows from the spray hose without spray head in place, clean or replace the spray head.

Let us know how you make out... ;)

Mark posted just ahead of me. Follow his advice and flust out the valve body.(see image) and then reassemble the diverter. Good luck, Tom

I would recheck your diverter installation.

I flushed the faucet out with the diverter removed. No sediment came out. When I remove the spray head I get flow from both the spout and spray line. However, it pulses and I have a lot of vibration in the faucet assembly. Could it be that I have a bad diverter? It is new and I just got it from Kohler.

Very possibly. But vibration tells me that it could be not installed properly.

Yes, you should get water from both : sprayer and faucet. Sprayer is constantly under pressure. Only when you push the handle, it activates flow and pressure flips diverter so it stops water from entering faucet spout.

I agree with Milo's respond, the diverter may not be installed properly, also you said when you replaced the diverter the water does not divert to sprayer and now you say the water is coming out the hose with sprayer head removed, may be I don't understand it sounds like you have problem with your sprayer head, try remove and install the diverter or replace it with a new one and also check the sprayer head if it is free of dirt, Thanks.

How can the diverter be installed improperly? It simply inserts into the body of the faucet. Also, to summarize:

1. With the water running from the spout when I push the spray handle I get a lot of vibration and water comes out of both. Very weak from the spray and pulsating.

2. If I remove the spray and turn the water on, I get flow from both (pulsating) and a lot of vibration.

3. I verified that all flow paths are clear by removing the faucet and inspecting.

I am sorry to repeat myself for the third time: but the symptoms you just descried indicate to me that diverter is most likely the culprit.

Maybe we would like to get some "third" party opinion from other Experts on this site. I may be wrong...

Now I would Suggest to replace the diverter it may be bad from stock, if this would not solve the problem change the cartridge, also did you know that some Kohler parts has life time warenty call therir customer care at 800-442-1902 explain your problem they may give a better idea and send you the correct parts for free, Thanks.

Having just replaced the diverter on my K-10412, and (finally!) getting the faucet to work correctly, let me add a couple of comments:

Check out the parts diagram at Kohler Plumbing

Make sure the old diverter is intact upon removal. If not, well... those little parts have to go somewhere; so there's a good chance the missing pieces are stuck in the line. While several culprits could cause a clogged line, the diverter pieces are prime suspects. Make sure all the parts are retrieved before inserting the new diverter and re-assembling the faucet. If the little rubber gasket from the diverter is lodged in the water line, neither a water flush nor compressed air will remove it. (At least it didn't move mine.) I had to disconnect the hose from the bottom of the faucet and snag the gasket with a wire and pull it out.

Also, here's the sequence for disassembly:
Place your drain covers or strainers over the drains. There are a couple of little parts that can fall down the drains. ( I learned this the "hard way" too.)
1. Handle set-screw cover (It's plastic, it just snaps in. Pry it out with a knife, probably best from the top or bottom as there are little securing tabs on either side. And yes, there is a "top" and "bottom" to it. That is to say, when you put it back upside down, it won't fit correctly. )
2. Handle (Loosen set screw with allen wrench.)
3. Bonnet (Should be threaded only hand tight. Wrap some tape on your plier jaws if you need to break it loose.)
4. Threaded ring (This is the big one that will accept a wrench.)
5. Valve (White cylinder about an inch tall. It just lifts out.)
At this point, you should be looking down into the brass body, which has three holes in it.
6. Spout. (The spout should lift straight up off the body. There is nothing holding it in place. If you must, pry gently under to spout. There's a nylon washer there, try not to damage it.)
7. Diverter (Inserted into the back of the body. Pliers may be necessary to get the old one out.)
Make sure you have all the pieces to the old diverter when you take it out. If not, start looking. They're in there... somewhere.
Insert the new diverter and reassemble in reverse order. You'll be done before dinner :-)

Good luck, and thanks to those who have contributed previously.

I had the same problem and was pulling my hair out until I came across clkinaz's answer. I flattened out a fishing hook and shoved it in the body of the faucet just under the diverter and pulled out the massive rubber stopper that had been attached to the old diverter. And voilà, everything worked perfectly! Thanks clkinaz!

Thanks for the update.
