😥 This concerns my own cooker, which has a ceramic hob with one halogen ring. The other day I was wiping the top and found a diagonal crack across the rear right ring. I have no idea how it got broken but I either need a new glass or a new cooker. Washvac list 3 different ceramic hobs for this model: Bin No. Q106479, Q107476 & Q104682 but with no photos of them, I don’t know which one I need. 😕 The cooker is quite old but this is the first time anything has gone wrong.
