Hi Pete, After watching this closely many many times, I concluded that Ira was right and that it is just the pump switching over to fill the steam boiler as it gets depleted, then switching back to the brew cycle. I can't say for sure if this changed from new, i.e. if the sensor for the steam boiler has gotten more sensitive, etc. Also have never figured out if it makes any difference to the quality of the shot--it's not dramatic in any case, but may be a little better when you just pull a shot without using steam at the same time.
One obvious solution is to pull your shot either before or after steaming, but that was unacceptable to me, since it defeats one of the main purposes of a double boiler machine. best, bmc On Sep 24, 2011, at 8:30 PM, [email protected] wrote: > Hello Everyone, > > I noticed something peculiar tonight that I wanted to mention to the > group.
