Wega owners might like to know that Dom's new P-Stat is available through EPNW for a very reasonable price. It looks like an improvement over the MA-TER that comes with the machine. I think it's worth changing out the MA-TER before it goes, and keeping it around as a spare. http://espressoparts.com/product/MZ_L271 Rick

Dom - I noticed from one of your "under the hood" pics that your water level rod is extended about an inch or so out of the white collar. Mine has always only been extended about 1/8". Does anyone know if extending the rod lowers or raises the water level inside the boiler?

Playing around with this, may help with steam volume and the heating elements ability to recover steam capacity quicker. Its a fine line and a balance that takes time to adjust, but on a smallish size boiler like the Lyra the benifits are great.

One thing I am still confused about, though - what did you mean by "fine line and a balance"? Does raising the water level increase the steam capability at the expense of something else? Since the laundry list for Dom's upgrades does not seem to include an upgraded heating element, perhaps the higher water level compared to mine explains how his boiler pressure does not drop significantly while steaming. I am going to try raising the levels right now.

There have been long discussions of boiler water level vs. steaming ability over on AC. I haven't experimented with it, but theoretically, more water should yield better steaming. This was neatly summarized by AndyS in a post some time ago: Click Here (groups.google.ca) In practice, it is probably important to retain at least some head space, but how much?? Rick

Quantity vs. quality. If the water level is too high then steam quality will suffer & you will start to get wet steam or carryover. On a HX machine it may also lead to higher water temperatures at the group as more of the HX is submerged.

On a HX machine it may also lead to higher water temperatures at the group as more of the HX is submerged. Posted October 24, 2005 link After raising the probe by about an inch, I noted the following: Steaming pressure did not drop as quickly or as much 3 degrees F increase in group head temp after 30+ minutes idle Flush required to cool HX water to proper brew temps increased by about 20% Flush required between shots increased dramatically No noticeable change in wet steam vs dry steam I was really tempted to leave it at the new increased water level, but the water flushing is killing me. My machine must have a tendency to run excessively hot. Most geeks seem to draw a 4 to 6 oz cooling flush prior to brewing. Even before increasing the water level, I needed to flush between 10 and 11 oz to purge superheated water from the HX. So, although steaming performance was improved significantly, I dialed down the water level probe to its original setting because I hate having to flush so much water all the time.

The problem occurs with more ater covering the HX and thus slowing the thermosyphon. You could play with the probe to find what works best. Maybe set it at .50 higher than original setting.

So this 2 hole tip doesn't fit on a standard Wega??

Is this the same P-stat?

Except this one is 1/4" instead of 1/8" the Wega needs.
