Not 4x4 related but....
Anthony Worral Thompson health grill, badged model by Breville, mod no HG 11, later HG21 may also be affected.
Cable inside overheats and melts, not before melting insulation/burning insulation around it, potential fire risk.
Similar to Belling ovens fault in the 80's/90's that caused several house fires (I was a Belling field engineer at the time).
Please be aware if you own one of these.
Niel.
