Junkers Euromaxx PCB ZWC28 1MF2K Ref. 87483005060
The control PCB manages the ignition, burner modulation, pump, and safety features of the Junkers Euromaxx ZWC28 1MF2K boiler, with reference 87483005060. If it fails, the boiler may not start, lock out, or behave erratically, displaying fault codes such as F7, which indicates ignition problems, or FA, which signals that it is not extinguishing the flame properly. This part is compatible with models like Junkers Euromaxx ZWC 24 among others. Replacement is recommended at any sign of malfunction.

How to check if ref. 87483005060 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 87483005060. 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 87483005060 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: no display, no indicators, nothing starts when the switch is turned on.
Cause: The PCB powers and controls the rest of the electronics in these models; if its power stage fails, no current reaches any component.
First, check that the boiler has power: plug, circuit breaker, and main fuse of the installation.
- 02
The control or room thermostat does not communicate with the boiler, even though it works well when connected to another boiler or tested separately.
Cause: The communication between the control and the boiler goes through the PCB; if its communication stage fails, control is lost without the control itself being faulty.
Check the wiring and connectors of the bus between the control and the PCB before replacing the PCB.
- 03
The boiler loses its programming and saved settings every time there is a power outage.
Cause: The configuration is saved in a memory with auxiliary power on the PCB; if that part fails, all recorded data is lost.
Check if the PCB has a backup battery and its condition before replacing the entire board.
- 04
The screen goes blank at times or displays strange symbols with no fixed pattern.
Cause: These faults usually originate from the internal power supply of the PCB or its microcontroller, and they are noticed on the display before a total lockout occurs.
Cut the power for a few seconds and check if the fault reappears immediately; if it does, it points to the PCB.
Fault codes from Junkers that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F7 | Problems with the ignition of the boiler. | The ionization signal is incorrect, which can cause issues with the ignition and operation of the boiler. If the boiler does not ignite properly and displays this code, it is possible that the PCB is failing and needs to be replaced. |
| FA | The boiler does not extinguish the flame properly. | The ion current remains after a normal disconnection, which may indicate a fault in the flame detection system. If you notice that the boiler does not extinguish the flame as it should and displays this code, it is likely that the PCB needs to 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.
