How to check if the ref. 87483003480 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 87483003480. 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 87483003480 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
When opening the hot water tap, the water heater does not ignite the burner.
Cause: The PCB detects the water flow and triggers the ignition spark; if it fails, the burner does not start.
Check that the water flow is sufficient and that the inlet filter is not dirty before replacing the PCB.
- 02
The water heater ignites but turns off after a few seconds.
Cause: The PCB cuts off the gas if it does not confirm the flame with the detection electrode, for safety reasons.
Check and clean the flame detection electrode before replacing the component.
- 03
The water heater shows no signs, no indicators or sound when the tap is opened.
Cause: A fault in the power supply to the PCB or a blown fuse leaves the unit completely dead.
Check that power is reaching the water heater and the status of the internal fuse before declaring the PCB faulty.
- 04
The water comes out at an irregular temperature, fluctuating on its own during use.
Cause: The PCB modulates the flame according to demand, and if it fails, the water temperature fluctuates.
Check the water pressure and flow rate first, as they also affect modulation, before blaming 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.
