I was about to buy the Technika, BUT when I found out the OPV valve and vacuum breaker wasnt set up to drain to the drip tray and would spray inside the machine, I changed my mind. It is a simple thing to do, yet ECM chose not to do this.. Why, i dont now. I also wasnt too comfortable with the return policy @ 1st line since they have a restocking fee.

Not sure where you got the info that the vac breaker drains inside the machine, but that's not case.  It drains right into the drip tray via a small exit tube at the bottom of the front of the machine beneath the group.

Also, as the machine has a rotary vane pump (which is quiet as a mouse BTW) there is no OPV in the machine.  It actually has an expansion valve, which again, drains into the drip tray.

The only thing that would drain inside the machine would the boiler pressure safety valve which opens when there's a problem with the boiler to stop it from exploding.  But if that opens, you have other problems to worry about other than water draining into your machine.  :)

Here's a good explanation of the setup:

And that's true.  There's no dancing around that one.

However, I can tell you from using it personally (compared to my old Cuadra and various videos I've seen of other HX machines in use) this is the most temp stable HX machine you can buy.   It, from what I can see on Eric's thermometer, requires almost no flush, even after sitting for a few hours.  My Cuadra would require about 8-10 oz to bring it down to brew temp after idling for more then an hour.  This machine?  Maybe an ounce or two tops, if that, and it's ready to pull.  

It was mind blowing to me the first time I used it.  LOL

awesome.. But how do you accept the fact that you really dont know the temperature you are pulling at and that different coffees taste differently at different temps..

From the pictures i saw of the boiler, the vacuum breaker did not drain into anything, it was the type that spurts water droplets right before the valve closes. The expansion valve does drain into the drip tray.

I do know the temperature when pulling shots.  Using Eric's thermometer, I can consistently pull a shot at any desired temp.

By checking with a Scace or using an Erics probe. Without these devices how does anyone know if their DB is accurate, is the offset set proper or if the DB machine needs .5 oz heating flush or a 2oz flush?

I like the convenience of the DB now but I miss pulling 3 consecutive shots in a row to sample different temps for a new bean on a HX.

I do think that the offset wont work throughout all the different seasons due to surrounding temps in the house.
