Category Overview
The electronic board is the brain of the combi boiler. When this critical part, which manages burner ignition, the circulation pump, the 3-way valve, the fan motor and all the signals coming from the sensors, fails, the boiler either does not run at all or locks out with an error code. In this section, which we have placed under the Combi Boiler Spare Parts parent category, you can find main boards, interface boards (control panel boards) and digital display boards compatible with different brands and models, Demirdöküm above all. At Yedepa.com we carefully select and list factory or exact-fit (OEM-equivalent) products that make the work of technicians and service companies easier.

Selection Criteria and Tips
The most common mistake when choosing a combi boiler electronic board is relying on visual similarity. Two boards that look the same may be incompatible due to a difference in software version or connector layout. To find the right part, we recommend the following steps:
- Read the boiler label: Note the brand, model and serial number. In series such as Demirdöküm Kalisto, Adegust and Atron, the interface board and the main board have different part numbers.
- Check the PCB code on the board: The code, usually beginning with "PCB", "REV" or "MAIN", is the safest way to find the equivalent product.
- Verify the source of the fault: Error codes such as E01 and E02 do not always originate from the board; they may also be caused by a sensor, the igniter or the gas valve. Measuring the peripheral components before replacing the board saves money.
- Beware of static electricity: Earth yourself before installation, and hold the board by its edges when removing it from the antistatic bag.
For models you are not sure about, contacting the Yedepa.com customer line with a photo of the label prevents buying the wrong board.
