Baxi Combi - Strofoam beads sucked in

I have a new Baxi GA40 combi boiler for my home heating and domestic hot water.

My neighbour undertook a home teardown and reconstruction. They clad their hoe with styrofoam. The contractors "sanded" the styrofoam for stuccoing, causing huge quantities of styrofoam beads to go all over the area, and some beads were sucked into my boiler air intake. Appears to have made it into the fan and into the burner chamber itself.

I removed the heat exchanger cover and scraped off some visible melted styrofoam, but its hard to tell how much is in the total system.

The unit now has a whining sound, when the burner fan is on, that reverberates throughout the piping. I presume this has something to do with disturbance of the air flow.

Is this stuff likely to be more a problem than just causing some noise? Will it carbonize and burn off over time? Should I get my home insurer involved to replace the whole unit, it was only 2 years old.

It is hard to dismantle everything to clean things out, just not sure whether this is just a nuisance or a more serious issue with the long term life of the equipment.

Hard to tell if any damage has been done without full disassembly and inspection of unit.
