I have been to look at this 2 ‘ring’ hob this morning and both displays flash Er2 as soon as either selector knob is turned. I can’t find any info in the manual, but inspection of the display board (under the control knobs) revealed something green and sticky spilled down onto it. Cleaned it off but same fault persists.
Just before paying out for a new board – does anybody know what Er2 refers to on this hob and whether a new board is likely to resolve the problem?
