Mike, I have two of the expensive grohe dispensers, less than one year old.
One stopped working a couple of months ago and your wd-40 worked. The other
stopped working two days ago. I found your instructions again on line. I
washed the parts well and let them dry overnight. Then, I sprayed them with
WD-40 silicone and re installed them. After a couple of pumps it works better
than new. Thank you very much for sharing your knowledge. Yours was the only
suggestion that made sense among those I found on line. I am surprised that
Grohe does not make that suggestion easily available on their site. I wish you
a Happy, Healthy and prosperous 2018
