Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
E62Calibration request.The PCB has been replaced or is without a service/programming key and the boiler requires recalibration; check in the TsP menu that P15/P31/P32/P33 are set to default and that the service key of the PCB is present before executing Auto Calibration.
E77Absolute current values reached.The combustion/modulation control on the PCB may be out of tolerance; rule out installation/ionisation/grounding and, if it persists, check condensation and connections to the board or replace the PCB and recalibrate (Auto Calibration).
E78Maximum regulation current value reached.The control electronics of the PCB can saturate the regulation loop; check wiring/ground/electrode and, if it persists, inspect the board (condensation, parameters) or replace it and perform Auto Calibration.
E79Minimum regulation current value reached.Fault in the electronic modulation/combustion control of the PCB; rule out combustion causes and, if it persists, check connections to the board and parameters, or replace the PCB and recalibrate.
E80Problem in the electronic driver of the gas valve.Fault in the valve driver circuit on the PCB; check wiring between the board and the valve and measure control signal; if the wiring/valve are OK, the cause is the board (replace and recalibrate).
E89Problem in the combustion feedback signal.The PCB may misinterpret ionisation/return due to an electronic fault; after ruling out electrode/flue/gas and wiring, inspect or replace the board and recalibrate.
E90Impossible to regulate combustion.Fault in the control electronics of the PCB among the probable causes; after ruling out combustion issues, check connections/ground and, if it persists, replace the PCB and perform Auto Calibration.
E93Unable to regulate combustion (temporarily).The PCB is listed as a possible cause (control failure); after ruling out electrode/draught/gas valve, check the board, parameters (P15, etc.) and perform Auto Calibration or replace the PCB.
E94Possible low gas pressure or flue gas recirculation.In addition to combustion causes, the PCB is documented as a possible origin; rule out flue/electrode/gas and, if it continues, check/replace the PCB and recalibrate.
E98SW fault, error starting the PCB.Software/start-up error of the PCB; after reset, the indicated solution is to replace the PCB and adjust P15, then execute Auto Calibration.
E99Generic fault (electronic hardware problem of the boiler).Hardware fault in the PCB; check power/reset and, if it persists, replace the board and calibrate according to the manual (P15 + Auto Calibration).
How do I know if this PCB is for my boiler?
Verify the reference 000019 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part.
What is it used for?
The PCB controls the ignition, modulation, sensor readings, and safety features of the boiler.
Is the boiler not igniting, locking out, or is the control board unresponsive?
After ruling out mains voltage, fuse, and connectors, a damaged PCB causes lockouts, blackouts, or erratic display. Repair the external cause before installing the new one.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
After installation, a technician must adjust the service parameters (type of gas, power settings) and check combustion and safety features.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
