How to check if ref. 356062800 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 356062800. 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 356062800 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 at all, neither the display nor the buttons on the panel.
Cause: The PCB does not power the rest of the circuits, leaving the boiler inert.
First, check the fuse on the PCB and the mains voltage in the boiler.
- 02
A fault code or indicator light turns on and does not disappear after resetting.
Cause: The PCB blocks the unit when it detects an out-of-range value in the sensors.
First, rule out low water pressure and blocked flue gas outlet, as these are common causes of lockout.
- 03
The boiler suddenly stops heating, as if it had turned off for no reason.
Cause: A fault in the PCB can interrupt the ignition command or the gas supply without external signals.
Try resetting the boiler from the main switch before changing 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.
