Hi, my name is XXXXX XXXXX I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. E21 is the temperature sensor is sensing more that 250 degrees so there may be a fault. If you unplug it for about 15 minutes that should clear the issue. Let me know if that helps.
Ok will try this - it is brand new - never been used
Got it out the box tonight, put it onto the holding shelf - plugged in and switched on - this code came up immediately
Only bought it this month - have been re-doing kitchen
Crazy. That is very odd. I think I would just return it at this point. Troublesome but even if unplugging it fixes the issue it still means that every time you look at it you're going to be wondering if it will do it again. If they have another then take it out of the box at the store and plug it in to test it.
Yes - we think it may be faulty - will do that - better safe than sorry!! Thank you for your help
You are very welcome!
