Subject: Jura S7 not working properly
 

I own a Jura Capresso S7, which has successfully pulled over 3,500 shots over the years.  I rarely use the steam function and hadn't used it in some time.  Tried it the other day and it worked fine.

However, when I tried to later make coffee, it failed.  Instead, it shot water through the steam wand and now that's pretty much all that occurs.  The puck comes out mostly or entirely dry and is dumped into the bin.

Jura said it sounds like a stuck solenoid valve and they suggested that I try to alternate between steam and the water spout to unstick it, but no luck so far.

The options they're giving me are either to repair it for $450, or to replace with another unit for a reduced price (but still more money).  One of the units is the J6 refurbished for $700 but most of the rest of them are more money that I want to spend.

So the questions:

  1. Any thoughts as to how to "unstick" the valve, or fix whatever the problem is, short of sending it to Jura?

  2. Is the J6 worth considering at $700?  I sense that the S7 is a better machine, no?

Thanks in advance!

Run some descaler through it to see if the solenoid valve unsticks.  If water is coming out the steamer it is stuck open, not closed, so it's not electrically failed. It certainly can't hurt to run the descale cycle.
The $450 sounds rather expensive. Even if that's going to include rebuilding of wear and tear parts, an hour's labour, assorted common parts and a solenoid valve should be $95, $55 and $75 even at high-end placed.
I believe that Jura Canada's service department has fixed rates for different models of machines.  The commercial machine flat rate is less than $300. An S-Series should be less than $250.

FWIW, I fixed it.  What I did was alternate between steam and the water spout aka "tea portion".  When I saw a tiny bit of water just barely start to drip out, I gave it a couple of hard whacks to the right side of the unit and it started working fine.

Jura said not to hit it, but I think that's what did the most good.

That's the $450 trick!

Juras can produce God Shots.  You just have to hit them once, then threaten when they forget.

I am editing this after reading the 1 line response I had originally posted.
The above sounds like a "Spousal Abuse" joke. It was not intended to read that way. It was just a Superautomatic jab. Sorry.
