Main ECO 30 Condensing Boiler - blowing internal fuses.

[Sisam]

Hi all.

Our Main ECO 30 boiler has suddenly started blowing the internal fuses.
All was fine until last night - when hot water was called for, both internal fuses blew. I replaced the fuses and the boiler powered up for a couple of minutes then blew the fuses again. I detected a faint electrical burning smell but this could have been the fuses.

Does anyone know of a common cause for this happening or what else to check for?

Cheers, Sime
