Hi, I have a Rangemaster Elan 90 with a fault on the induction hob. The switches for the hob have had an intermittent fault for a while and they need turning back and forth to wake them up.

But now each ring displays L and the hob doesn’t work at all. I thought it might be a child lock but it won’t unlock by turning the two left hand controls anti clockwise.

Can anyone advise me please?

Thanks
