The Junkers ZWE24-1KDP23S2800 PCB (control board) Ref. 87483002130 controls vital functions of the boiler, such as ignition, burner modulation, and the pump. If it malfunctions, the boiler may fail to start, lock out, or behave erratically, displaying the fault code E0 due to an internal fault in the printed circuit board. This board is compatible with several models from the Junkers Eurostar and Euroline ranges, among others. It is recommended to replace it upon noticing any of these symptoms or upon receiving the indicated fault code.

How to check if ref. 87483002130 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 87483002130. 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 87483002130 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 ignites, tries to operate, and shuts down after a few seconds for no apparent reason.
Cause: The PCB controls the safety signals during startup and cuts off the supply if it detects any anomaly, whether real or a reading error.
Check the flame sensor and the flue before replacing the PCB for this symptom.
- 02
The circulation pump keeps running even though heating is no longer needed.
Cause: A relay on the PCB gets stuck and keeps the pump continuously activated.
Check that the thermostat is not constantly calling for heat before assuming it is the PCB.
- 03
The display shows strange characters or turns off and on repeatedly.
Cause: A fault in the PCB affects the circuit that powers and controls the display, causing erratic readings.
Check that the mains current is stable at the boiler before replacing the PCB.
- 04
After a lockout, the reset button does not respond: it neither beeps, nor restarts, nor changes the fault code.
Cause: The reset button is managed from the PCB, and if its circuit fails, the reset command is not executed.
Hold the button down for a few seconds longer than usual and make sure there is no dirt or play in the button before changing the PCB.
Fault codes for Bosch Junkers that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| E0 | Internal fault in the PCB (control board). | The PCB self-diagnosis detects an internal fault or loss of communication/power supply; first check the 230 V network, polarity, and grounding, and measure the low voltages (+5/+12 V) and connectors on the board. If it persists, replace the PCB. |
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.
