Have a kohler forte kitchen faucet that the sprayer is no longer working. It appears to be the diverter valve but I have no idea how to get to it. Where is it located and how do I replace [email protected]

Remove sprayer and hose from faucet body.
Remove handle and cartridge.
Pull up on body.
Replace parts and reinstall in reverse order.

Hi! Yes it sounds like the spray diverter needs replacing. Kohler .com will have this part online or you could try a plumbing supply shop.

Check to be sure the hose isn't kinked somewhere below the faucet. If there aren't any kinks there is likely debris stuck behind the nozle screen, remove it and clean it- or your handle mechanism is broken. Replacement handles and hoses are fairly inexpensive if you need one they're easy to find at most big hardware stores or on Amazon

First thing to check is if it has a strainer on the spout that has debris. The second thing is if you have a sprayer attachment the diverter valve is a chronic problem with kitchen faucets.

Shut off water supply Under Sink: · Unscrew brass connector for spayer hose · Disconnect single water line to faucet bysqweezing lever on connector and Gently pulloff. · Loosen two screws on faucet base washers thenunscrew the washers on thebrass faucet shaft ( NOTE: Have someone hold the fauct so it does Not accidentlyfall in sink when the support washers are removed) · Take faucet out of sink · Unscrew brass collar at base and remove · Remove Set Screw on lower body of faucet · Pull out Brass Mechanism from faucet · The Diverter is located in the Brass mechanism · Remove the Washer · Pull off the small top valve in center of theDiverter, if still there · Using a large wood screw that fits/screw intothe exposed hole In the center of The plasticdiverter, screw it in and pull out the remaing part of the old diverter · Flush out Faucet to remove any remaining debrie · Replace with new diverter and replace washer · Grease all areas that where greased when mechanismwas removed Remove & clean the faucet Airrater and replace only afterEVERYTHING has been Completed soyou can flush the faucet out again into the sink, then replace.

I had a similar problem with my relatively new Forte model. I disassembled the handle, removed the retaining ring and the valve assembly. I thought at first it was the valve assembly but wasn't convinced. I continued to remove the entire faucet hub by gripping and pulling straight up. When I did, the diverter valve popped out of the back to the counter behind the sink. I cleaned all the parts up, made sure all the rings were in place, presse the diverter securely into place back in its hole, and reassembled the rest of the parts. That seemed to do the trick. I'm guessing that the diverter lost its seal and was displaced inside the hub. Hope that helps someone else.

Go to page 15 it has an exploded view of the faucet.

sounds like sticky diverter should replace it

THe diverter inside of the faucet is malfuncting. Remove and replace the diverter valve. It is located right under the spout assemble.  

try soaking it in some CLR calcium lime and rust remover .
