verify that the ultrasonic cleaning
tank has been properly emptied.
To clean the valves, start the

pump water back and forth through
the valves and may remove debris
stuck in there.
To start Machine maintenance
navigate to the Degas program
in the menu. Press and hold the
left button and immediately press
the right button. If this solves the
issue, then clean the machine with
vinegar as described in Cleaning
