I have a Grohe soap dispenser and it has quit working for me. It is as if it gets stuck after you push it down and it seems to leak the soap out of the bottom part of the dispenser getting soap all over counter. Then I have to pull it back up manually. I have cleaned it as good as I can but nothing I have tried works so I was curious to know if there is something I can do to repair it. The faucet & dispenser are approximately 6 years old. Any help would be appreciated.

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.
