Symptoms that require diagnosis on the PCB 356062800
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.
