The Bezzera BZ10 espresso machine is one of the most popular domestic espresso machines the oldest espresso machine in the world makes. To summarize what this espresso machine is, a solenoid operated espresso machine which get’s its water from a water tank of the back of the machine.
This espresso machine, the Bezzera BZ10, is fitted with a vertical single heat exchanger (HX) boiler. In the bottom of the boiler you have the main 1200W heating element, which can be 110 or 220/230V.This boiler is filled from a water tank on the back of the espresso machine. To pump water into this you use a Ulka vibration pump. This pump is also used to brew the coffee.
The brewing group used on the Bezzera BZ10 is not one of the E61 style type. But a brewing group which is solely used by the Bezzera brand. This brewing group is a solenoid operated brewing group, made up out of 2 main components. The main body and the portafilter coupling bell. A other feature you don’t see that often on a domestic espresso machine is that this brewing group has been fitted with a heating element.
This coffee machine is not a volumetric model, otherwise it should have been fitted with a flowmeter. In this case the machine is operated by moving a switch up and down to start and stop the brewing process.
A few questions we get often asked by our customers.
How do I check the pressure of my Bezzera BZ10 espresso machine?
The Bezzera BZ10 has been fitted with a double scale pressure gauge, or manometer. So you will see 2 needles, one is for the pump pressure and the other is for the boiler pressure. The boiler pressure goes from 0 up to 3 bar and the pump pressure goes from 0 up to 16 bar.
Is the Bezzera BZ10 espresso machine fitted with a water tank or a main water connection?
The Bezzera BZ10 espresso machine is fitted with a water tank, from this tank the water is pumped, with a Ulka vibration pump, towards the brewing group and into the boiler. So you won’t be able to fit a main water connection to this espresso machine.
What kind of brewing group does the Bezzera BZ10 have?
This model of Bezzera espresso machine is fitted with a solenoid operated Bezzera ring brewing group, so it hasn’t been fitted with a E61 style of brewing group.
What kind of temperature control mechanism does the Bezzera BZ10 have?
Well this does depend on how old your Bezzera BZ10 is. Seen you have 2 model versions. There is a pre- 26-06-2010 and a post 27-05-2010 version. The older type is in it’s original configuration isn’t available anymore, for this is a relay rebuild kit available which is the same as the new model.
They are both operated with a Ma-ter pressure switch with is fitted with a safety valve and with a relay. The older ones had a build on relay, but the latest ones have a separate relay.
Can I use the Bezzera BZ10 espresso machine for commercial purposes?
We would not advice to do so, seen the capacity is too little to proper function in a bar or a restaurant. For a small office this espresso machine would be a good solution, as well as the use in a kitchen.
