Stock · 1 unit

The Junkers Eurostar and Cerastar boilers use the Junkers Bosch PCB ZWE 24 3HKD 23 Eurostar HIT Ref. 87483002670, which acts as the brain of the system, controlling the ignition, burner modulation, pump, and safety features. If this board has faults, you will notice that the boiler does not start, locks out, or operates erratically, potentially displaying the fault code E0, which indicates an internal fault in the printed circuit board. It is compatible with several models, such as the ZWE 24-3 MFKD and the ZWE 28-3 HAD, among others. It is recommended to replace it upon detecting these symptoms to avoid further issues.

Guide

How to check if ref. 87483002670 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.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 87483002670. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms and faults that the PCB 87483002670 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 shows no signs when turned on: no display, no lights, no noise from the fan.

    Cause: The PCB is not supplying power to the ignition circuits.

    First, check the main fuse of the boiler and the thermal switch of the installation; rule them out before considering that the PCB is faulty.

  • 02

    It locks up with a fault code on startup, and that code changes every time it is restarted.

    Cause: The PCB incorrectly interprets the signals and generates faults that do not correspond to a real failure.

    Note the exact code during two or three consecutive resets; if it varies or disappears on its own, the PCB is more suspect than a specific component.

  • 03

    The room thermostat does not turn on the boiler, although the manual control of the boiler does work.

    Cause: The circuit of the PCB that receives the external demand signal is not processing that input.

    Directly bridge the terminals of the thermostat on the PCB to rule out a wiring issue before replacing it.

  • 04

    It starts normally but turns off by itself after a few minutes, repeatedly.

    Cause: This is typical of PCBs with solder joints or components damaged by heat, which fail when reaching the operating temperature.

    Check if the cut always occurs when cold or only when the boiler has been hot for a while; the latter suggests a problem with the PCB.

Fault codes from Junkers that this part resolves.

CodeFaultDiagnosis and solution
E0Internal fault in the PCB.The self-diagnosis detects an internal fault in the main board; the manufacturer prescribes replacing the printed circuit board. Beforehand, check power supplies/connections and fuses and reset: if the E0 reappears, the PCB is defective.

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.
