Kohler soap dispenser leaks onto counter

likely drain pump blocked could have water in bottom base ie leaking

Probably the chack valve is stuck either with hardened soap or a piece of trash. Wash out the assembly completely flushing everything with ample water. It should work after that.

Get the plastic guts of the thing apart (again, I know). Soak in CLR, was thoroughly in warm water and dry. Squarely cut back the original squarely cut end of the tube about one-half inch with a razor knige. Reinstall the tube FULLY onto the base of the pump as far as it will go.
I no longer refill from the top. I now bite-the-bullet and crawl underneath in the cabinet, unscrew the bottle and refill.

Sounds like there might simply be old soap caked on the inside of the dispenser head and feed tube. Best thing to do is have a sink filled with HOT water and just put the head portion in there to soak for a while. This should loosen the old soap enough to either dissolve or at least get it moving again. You can also take what soap is still in the dispenser out and put in another container, taking time to rinse the container with hot water as well and then filling it with hot water as well to test the pump action of the head, again using this action to help clean the insides of the pump. Short of this doing the trick, it may just be time for a new one. Good luck.

I'm not sure if it can be repaired or not, but lowes carries the same dispenser that came with faucet. To replace unscrew bottle from under counter now you remove plastic nut that holds the body to counter and install new one.

maby minor crack between the the treds on the bottle that screws in to the pump or a crack in the bottom of the pump and you may not see it because the pressure of the pump isint in the bottle when you un screw it tot look at it

Pull the dispenser out. Put it in semi hot water foe a few minutes to clean it. Then put the pickup tube in a glass of water and pump it untill water comes out. They get clogged with soap after so long.
Good Luck

Hi.. Its a breather or "vent "and its clogged. Remove the drain tube under the sink that runs from the vent to the connection on the drain( under sink). Clean vent and replace. Please send me some Positive feedback if I've help. Thankyou!
