      Howdy,

      My machine is now leaking out of the back flush valve (i think that is what it is called). I leaked all over the place. I took it apart but I am not sure why it is doing this. Any suggestions on how to fix it? Could it be a clog in the group head?

          Tex, It is dripping out from the bottom of the solenoid discharge area (#1 in the diagram), the area that shoots out the water when you backflush the machine.

            Tex,

            It is dripping out from the bottom of the solenoid discharge area (#1 in the diagram), the area that shoots out the water when you backflush the machine. 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.

            You ve got leaky 3-way valve; probably because it hasn t been getting a regular backflushing. See this image:

              You've got leaky 3-way valve; probably because it hasn't been getting a regular backflushing.

              See this image: http://groups.yahoo.com/group/BUG-is-Bunn/photos/album/756389236/pic/345709006/view & this one: http://groups.yahoo.com/group/BUG-is-Bunn/photos/album/756389236/pic/335671855/view

              The piston (leftmost piece in the first image) moves up & down inside the valve cylinder. The spring holds the piston in place over the hole in the valve's base (second image) when the valve is not powered.

              The 3-way works by way of an electro-magnet that pulls the piston from the hole when it's powered up. If the machine's not frequently backflushed, coffee lacquer builds up in the valve and it'll leak.

              Disassemble the 3-way valve, soak the pieces in a strong detergent and rinse them well. After you reassemble everything the leak should be gone and you'll be good to go. 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?

                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.
