Introduction

If the display shows error 5, the flow meter is reporting insufficient flow. The electronics can be disturbed, the thin inlet duct is often dirty - or the water stops later, e.g. because the heater is calcified. Thus guide shos, how the flowmeter is removed, opened and revised or replaced.

  1. Disconnect the power plug!
    • Disconnect the power plug!

    • Remove the water tank.

    • Remove all the coffee beans.

  2. Pry up with a plastic opening tool at the bottom edge of the chrome-plated cover to lift up the coffee dispensing spout. This cover is often very tight, so you have to pry hard and hope that the part does not break. When the lower edge of the spout is released, you can pry on the side edge until the chrome cover comes off completely.
