BERETTA Gas Boiler Error Codes

To restart the boiler, switch the mode switch to ON, wait five to six seconds, then move it back to the desired position. After that it will start automatically. If the normal operation can not resume, call the service technician.

 

Error A01 - Blocking by the absence of flame. Shutdown of the control board malfunction. Five unsuccessful attempts to ignite. Make sure that the gas valve is open. Make sure that there are two ignition electrodes.

Error A02 - Limit thermostat blocking.

Error A03 - Termination of work on the smoke extractor pressure switch.

Error A04 - Hydrostatic pressure switch blocking.

Error A06 - Malfunction of NTC dhw sensor.

Error A07 - Malfunction of NTC heating sensor.

Error A11 - Flame simulation.

Error A 20 - After the gas valve closes, it takes too long before the flame disappears. Check that the gas valve is working correctly. Replace the gas valve.

Error A 24 - Fan error. The measured fan speed changes too fast compared to the read speed. Check the fan. Check the electrical connection of the fan. Replace the fan.

Malfunctions causing the final shutdown of the Beretta boiler

 

It is required to reset the unit using the Reset button.

 

Error 10 - Blocking due to lack of flame.

Mistake 11 - False simulation of the flame.

Error 20 - The limit thermostat is damaged.

Error 21 - The burner thermostat is faulty (MIX CSI models).

Error 22 - The flue gas thermostat is inoperative (CAI models).

Error 30 - Defect of the smoke extractor (MIX CSI models).

Error 40 - Insufficient pressure in the heating system.

Error 42 - The water pressure sensor is faulty.

Error 50-59 - The electronic board fails.

 

Temporary malfunctioning, the Beretta boiler automatically attempts to restart the operation

 

Error 31 - Smoke exhaust pressure switch (MIX CSI model).

Error 41 - Insufficient pressure in the heating system.

Error 60 - The DHW temperature sensor is damaged.

Error 71 - There is a problem with the temperature sensor in the heating system.

Error 77 - Low temperature thermostat defective.

Errors reset automatically

 

E23 - Internal error. Replace the main control board.

E34 - The frequency in the power network is not 50 Hz.

E02 - NTC-1 open (sensor at the output of the device). The sensor on the supply line in the primary circuit is not connected or there is an open in it.

E04 - NTC-3 is open (DHW sensor). The DHW sensor is not connected or there is an open circuit in it.

E18 - NTC-1 - short circuit. Short circuit on the sensor of the supply line in the primary circuit.

E20 - NTC-3 short circuit. Short circuit on the DHW sensor.

E33 - Phase and neutral are reversed. Correctly connect the phase and neutral wires.

E34 - Reset button error. The button was pressed more than 7 times for 30 minutes. Wait until the error disappears. If the error is still present after a maximum of 40 minutes, replace the card.

E35 - Error of differential water pressure switch (contact open). Make sure that the water flow in the circuit of each unit is correct. In each unit, the flow rate should be 2 m3 / h. Replace the water pressure switch (setting 500 liters / hour).

E37 - Flame detection error. Clean the electrodes. Replace the electrode.

E38 - Short circuit of the flue gas sensor. Check the connector of the flue gas sensor. Replace the flue gas sensor.

E39 - The contact of the flue gas sensor is open. Check the connector of the flue gas sensor. Replace the flue gas sensor.

E40 - Check the frequency in the power line.
