4. Settings
Times when the calibration should be carried out automatically.

Troubleshooting

7. Warning: Calibration water HE/boiler

• Check water valves via diagnosis.
• Check if station or drain valves are leaking.
• Change calibration time to a moment when action can be observed (see 4).

8. Warning: Calibration milk

• Check milk filter.
• Check milk valve via diagnosis.
• Check milk pump.
• Check if station or drain valves are leaking.
• Change calibration time to a moment when action can be observed (see 4).

9. Warning: Calibration milk powder

• Check powder supply via diagnosis.
• Check powder supply outlet visually.
• Check if station or drain valves are leaking.
• Change calibration time to a moment when action can be observed (see 4).

10. Warning: Calibration

• 120 days after the last calibration of detergent, additives and concentrate.
  Or if calibration value differs too much from the value of the last calibration for water HE, water boiler, MP and milk.

• Confirm warning with ENTER button.

• Recalibrate components that are displayed.

• Check with arrow left or right if there are more components to be calibrated.

11. Procedure if checking the calibration scale failed

• Readjust the scale via diagnosis.
• Make sure the feeder is in a stable position.
• Make sure potential equalization is done correctly.
• Have it checked by a technician that the card of the calibration scale is correctly seated on the main board.
