PCB Junkers Bosch Thermotechnik ZWE24-1KDP23 Ref. 87483002130
When you turn on the hot water tap or activate the heating, the Junkers Bosch Thermotechnik PCB ZWE24-1KDP23 is responsible for controlling the ignition, burner modulation, and pump operation. If this part fails, you will notice that the boiler does not start, locks out, or exhibits erratic behavior. This board is compatible with models such as the ZWE24-1KDP31 and others from the Eurostar and Euroline ranges. It is recommended to replace it if you experience these symptoms.

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 is completely dead: neither the pilot light nor the display turns on.
Cause: Without the operational PCB, power does not reach the other components of the boiler.
Check the fuse on the PCB before purchasing it; if it's blown and without burn marks, it might just be that.
- 02
Different fault codes appear every few days, with no clear pattern.
Cause: The control electronics are experiencing intermittent faults due to an internal component that is beginning to degrade.
Note which fault code appears and at what moment (cold start, after several hours); a repeated pattern points more to the PCB than a random fault.
- 03
The boiler turns off by itself and loses the time or the programming that was set.
Cause: An internal voltage drop in the PCB resets the microcontroller as if you unplugged it.
Check if the reset coincides with a cold start or with several hours of continuous use; that thermal pattern is typical of the PCB.
- 04
The remote control or the boiler panel suddenly stop responding.
Cause: The communication between the PCB and the control panel is interrupted when the microprocessor hangs.
Turn off the main switch, wait half a minute, and restore power before considering the PCB as broken.
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.
