Hi did you manage to find out what this fault was as I have the same problem! I switch it on and it gives out ten bleeps, then about another minute later another ten beeps and so on, the 4 LED lights blink at me too, its just out of guarantee, so annoying! Apparently will cost be £90 just for a call out!!!!
would love to know if you resolved this?
