How to check if ref. 8707207277 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 8707207277. 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 8707207277 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 not responding: there is no display, fan, or ignition spark.
Cause: The PCB does not distribute power to the other components of the boiler.
First, check the main fuse and the thermal fuse of the installation before considering that the PCB is damaged.
- 02
The boiler turns on briefly and then turns off, repeating this cycle continuously.
Cause: The PCB interrupts the process because it detects a fault, whether real or erroneous.
Measure how many seconds it takes to turn off and if it always happens at the same moment in the cycle; this pattern helps to differentiate between the PCB and the sensor.
- 03
There is no hot water, even though the boiler seems to be on and functioning.
Cause: The PCB may not be sending the correct signal to the gas valve or the circulator for the domestic hot water mode.
Check if the problem also occurs in heating or only when requesting domestic hot water; if it is only in DHW, it is more likely to be a fault with the PCB.
- 04
The display or the LEDs are flashing with a code that is not in the manual, or it changes with each reset.
Cause: A damaged PCB can provide inconsistent diagnostics due to faults in its electronics.
Note the exact code during several resets; if it varies without a pattern, suspect the PCB before an isolated component.
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.
