Our oven door has the usual glass front, consisting of an inner pane of glass and an outer pane. During cleaning, water has somehow got onto the INNER surfaces of each pane, leaving long thin stains from top to bottom.
I took the door back to where we had bought the cooker. The people there said "this was a common problem", and "all I had to do" was completely disassemble the door to get at the inside of the glass.
I think this is nonsense. I have never seen such a problem in any oven door before. Also, there is certainly nothing in the instruction manual that tells me to unscrew all the retaining screws that hold the door together and then remove the glass from the door to clean it!
I believe this problem is either a design fault or a manufacturing fault. Anyone else had this problem?
