Kitchenaid proline
« on: October 21, 2013, 09:43:17 AM »
Hi! I like this new group very much!!  I have a kitchenaid proline that I bought recently on ebay for US 125, it is one of the first models that have a leak near the water reservoire.
After a good descaling and cleaning, changed the boilers gaskets and the group gasket (same parts than gaggia classic) Then, to my surprise adjusting the OPV was really simple, it can be reached without opening the machine, there is a hole on the back that can be accessed when removing the water reservoire. Just inserted an allan hex key and with 3/4 of a turn... Voilá the pressure adjusted to 9.5

And I've added a link to the library that brings anyone looking for how to adjust that OPV right back to this thread.

It  turns out that my OPV was adjusted way too high resulting in sharp, grassy tasting espresso and 15 - 20 second doubles. The pressure was so high that using a very fine grind and a very heavy tamp didn't slow the extraction very much. I inserted a 5mm hex wrench, and moved it from the right side to the left several times - looking at the back of the machine. It was easier to turn in this direction. Eventually, the pressure came down, so I can control the flow much better.

But then I discovered another problem - the water from the OPV doesn't flow into the reservoir - it flows down the wall and under the drip tray! This looks like a design flaw to me.

I found a small piece of plastic tubing and glued it into the hole where the water comes out, to guide it straight down into the reservoir. There is about 3/8" clearance from the top of the back of the water reservoir to where the water exits, so I made the tube just long enough to clear the back of the reservoir.

I'll post results and pictures next time.

The tube resolves the problem. Water from the OPV now flows into the reservoir.

I had to do the same, small fix, great results! My kitchenaid is dead since the relay burned and I have not been able to source one... :/ great machine, but sometimes difficult to find some parts.
