My microwave oven has failed several times with need for display board and buttons replaced by various engineers. Finally failed again with grill starting without any signs when operating microwave only. Nearly had fire as direct result. When calling customer service to speak to engineer to see if there was a reset or check to avoid need to replace two ovens at cost of about £1600 I was told could only talk with product advice, as no technical person in head office at UK to speak and all engineers on the road. Advised to call back and go to option 4. I decided to write this review instead. Just wanted advice if a reset or known solution could be tried. Sadly their office personnel know nothing technical about their products. What a disappointment.
