Accessing the inside – Domobar Junior

Power off the espresso machine and disconnect the plug from the outlet. To avoid burning yourself, allow the machine to cool down at least 2 hours before moving forward.

Remove the top cover and the water tank inside.

From here you will have access to the following:

• the manufacturer’s label which has the serial number and certifications.
• the pressurestat adjustment – using a flathead screwdriver, turn clockwise for more boiler pressure, and counterclockwise for less boiler pressure.

To gain access to the inside, the body panel must be removed. On the left and right sides of the machine, there are 3 screws (6 total). Once removed the body panel will slide off.

You will now have side access to the inside to diagnose the machine.

On the left side where the vibration pump is, you will be able to adjust the OPV. Using a flathead screwdriver, turn clockwise to increase pressure, counter clockwise to decrease pressure.

To gain full access to the inside, there are 2 Philips-head screws on the bottom and top of the machine. If you have to tilt the machine on its side to remove the 2 bottom screws, lay the machine on a towel or pillow. Make sure the machine is not laying on the electrical cord.

You will now have complete access to the inside to replace parts.

The inside panel has wires and the water tank hoses attached to it. There should be enough slack to lay it down flat. We don’t recommend hanging it off the side of a table or work bench.

On the bottom of the machine, there is a panel that gives you easier access to the heating element. It is held in by 5 Philips-head screws.
