Reasons for appearance:

• Lack of water
• Air lock in the system
• Incorrect water supply connection settings
• Technical malfunction

To reset the error, press the CONTROLLER REBOOTswitch . If the error persists, start the pumping water in the service menu.

If the error reappears after rebooting, run diagnostics:

• Make sure that the taps and the pump/water supply switch are installed in the correct position, corresponding to the connection;
• The pump is at the bottom of the tank, the water has not run out (with this type of connection);
• The pump hose is not pinched or kinked;
• The pressure in the water supply system (with this type of connection) is not lower than 0.15 - 0.8 MPa (1.5 - 8 bar).
• The water level when rinsing the mixer/pumping water is not less than the optimal level (picture below):

Each connection type uses a separate setting.

To adjust the settings, you'll need a small “-” screwdriver. The adjustment is made by turning the adjustment screw on the UPS board at the backside of machine.

1. Using a screwdriver, turn the adjusting screw clockwise by 1 turn.
2. Run the mixer flush (or water pumping) in the service menu.
3. Visually check the water level in the mixer and readjust if necessary.

If there is excess pressure, adjust the pressure back by turning the screw counterclockwise.

You will need a “+” screwdriver to adjust.

1. Using a screwdriver, turn the regulator clockwise by 1 turn.
2. Run the mixer flush (or water pumping) in the service menu.
3. Visually check the water level in the mixer and readjust if necessary.

If there is excess pressure, adjust the pressure back by turning the regulator counterclockwise.

Question: I ran out of water, and the machine has been in an error state for a while. When I restart and pump, the water doesn't flow, or flows very slowly, and the settings don't work. What should I do?

Answer: Turn off the machine's cooler for 30 minutes, then pump the water. Without water, the cooler freezes and shuts off the water supply.

Question: The machine doesn't reset the error after multiple reboots. The pressure is normal, and water flows when rebooted. Sometimes the error resets, but reappears the first time I make a drink. What should I do?

Answer: The watermeter needs to be changed.

Question: When resetting, no water flows; the machine operates on a submersible pump. The valves and toggle switch are installed correctly. What should I do?

Answer: Reset the machine and inspect the pump. If the pump doesn't turn on after resetting, change it.
