Hi guys, I changed the AV and the machine appears to be working as normal.

I am lucky to have an Elektra service centre close by, the engineers in there are very very helpful, the AV cost me £3

Here's a link below, they service most commercial and domestic machines and they will post parts worldwide I believe.
