Junkers PCB ZWE24-1KDP31 S2800 Ref. 2248300380
The Junkers ZWE24-1KDP31 S2800 Ref. 2248300380 PCB is a crucial component that controls the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior. This part is compatible with models such as the ZWE24-1KDP23, ZWE24-2KDP23, and ZWE24-2KP11, among others in the Junkers Eurostar and Euroline range. It should be replaced when the fault code E0 appears, indicating an internal fault in the control board.

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 restarts by itself from time to time, especially right after starting up in cold conditions.
Cause: The filtering capacitor on the PCB loses capacity with use and allows voltage fluctuations that reset the control.
Check if the reset occurs only when cold or also when hot; if it only happens when cold, this fault may be the cause.
- 02
The boiler does not start at all, with no lights or display.
Cause: Without the control board, there is no power supply for the rest of the components.
Check the fuse on the PCB and ensure that power is reaching the input connector before replacing it.
- 03
The circulation pump never stops, even when the boiler is turned off.
Cause: The relay that controls the pump has stuck on the PCB and does not cut the circuit.
Listen for the relay click when turning off; if the relay does not sound, the fault is in the PCB and not in the pump.
- 04
Fault codes appear that do not correspond to any component you have checked.
Cause: The PCB misinterprets the signals it receives from sensors due to an internal fault in its electronics.
Check the sensor connectors before replacing the PCB: a loose connection can give the same fault code as a real fault.
Fault codes from 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.
