PCB CG/00-EK Ref. 2799110
The PCB CG/00-EK Ref. 2799110 controls the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or operate erratically. You may notice issues such as system errors, including 30, 31, 32, 33, or 99. This part is compatible with boilers from the EK range, such as the models GU-EK 18, GU-EK 24, GG-EK 18, and GG-EK 24, among others. It is recommended to replace it upon detecting any of these symptoms or errors.

How to check if the reference 2799110 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 2799110. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB 2799110 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite and shows no signs on the control panel.
Cause: The PCB does not receive or distribute power to the other components.
Check the fuse on the PCB and the input voltage before replacing it.
- 02
The thermostat requests heat and the boiler does not respond, as if it is not receiving the command.
Cause: The PCB does not process the demand signal sent by the room thermostat.
Directly bridge the thermostat terminals on the PCB to check if the boiler starts before replacing it.
- 03
The boiler ignites correctly but shuts down after a few minutes for no apparent reason.
Cause: The PCB interrupts the cycle due to an incorrect reading from one of the connected sensors.
Check that the temperature sensors are properly connected to the PCB before replacing it.
Fault codes for Wolf that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 33 | Factory settings CRC error: invalid EEPROM data from "Masterreset" (CRC error in default values). | Corruption of the EEPROM in the control board; after reset, if the code persists and the parameter plug/BCC is correct, the action indicated by the manufacturer is to replace the board. Verify 24 VAC/5 V voltages and connection of the parameter plug before replacement. |
| 31 | Burner CRC error: invalid burner EEPROM data. | Memory fault in the PCB/FA; if it persists after a reset, the manuals indicate replacing the PCB. Check wiring and power supply before replacement. |
| 30 | Boiler CRC error: invalid EEPROM data for the 'boiler' assembly. | Dataset corruption in the PCB; after a reset, if it is not corrected, the official procedure involves replacing the PCB. First, check voltages and ensure there are no pending parameterization/updates. |
| 32 | Voltage fault 24V: fault in the 24 VAC supply (check fuse on PCB in *GB). | Fault in the 24 VAC supply generated/monitored by the PCB (fuse/regulator on PCB). Measure 24 VAC at terminals and PCB fuse; if everything is correct and 32 persists, replace the PCB. |
| 99 | Internal electronic/PCB error (combustion automation system fault). | Internal fault of the control/FA on the PCB; the brand indicates checking connections (e.g., fan PWM and network) and resetting; if it persists, the PCB is faulty and must be replaced. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
