Error #121, 122, 123, 124: Beater High Error
The control board is not reading the proper value from the beater motor.
1 Run a defrost cycle to reset the motor baseline value.
2 Run a beater circuit diagnostic to determine the problem or refer to error #58X in this manual.
Error #130: Board Failure
The control board is not functioning properly.
1 Cycle the power to the dispenser to see if it will clear the error.
2 Replace the control board.
Error #140: Low Regulated CO2 PSI
The regulated CO2 pressure dropped below 50 PSIG (345 kPag).
1 Ensure the CO2 supply is not low.
2 Check the "carbonation" regulator on the header tray and ensure it is set to 60 PSIG (414 kPag).
Error #150: High Regulated CO2 PSI
The regulated CO2 pressure is above 70 PSIG (483 kPag).
1 Check the "carbonation" regulator on the header tray and ensure it is set to 60 PSIG (414 kPag).
Error #160: Low Line Voltage
The voltage supply is below 200 volts.
Install a boost transformer. Even if the voltage is slightly above 200V, a boost transformer may be
needed as fluctuations in power during the day, or during dispenser operation may cause it to
drop below 200 volts and shut down the dispenser.

Note: For optimal performance and to avoid component failures, FBD recommends dispenser be
supplied with 230 VAC ± 10%.
Error #170: High Line Voltage
The voltage supply is above 254 volts.
Install a buck transformer.
1
Note: For optimal performance and to avoid component failures, FBD recommends dispenser be
supplied with 230 VAC ± 10%.
Error #180: LPSI Transducer
The low side refrigeration pressure is not reading correctly.
1 Ensure the pressure transducer is plugged in.
2 Replace the transducer if faulty.
