      Actually, remove the entire 3-way valve & base; and both fittings on top of the group & the parts inside. Then remove the shower screen & dispersion plate.

      Once everything is removed you can visually check that all the passages are clear. There was once an owner of an ES-1A who found the internal passages of his group completely blocked by gunk. Since the 3-way is acting up it's a good idea to check it all out.

Just be sure to backflush the machine with fresh water every day and with detergent once a week. Of course, you could backflush more frequently if you wish?

It leaks whenever I turn it on, and I have to turn off the water under the sink to prevent it from dripping. It is a continuous drip. Not sure if there is a blockage somewhere that is forcing the water out or if there is a bad o-ring. Anyway, any advice is appreciated.
