Bezzera BZ10 

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.
