Hello I have a Rangemaster oven and due to a power cut the timer/clock has gone onto auto and therefore flashes 0:00 then auto continuously. We have tried turning the power off and on again and also holding the 1st and 2nd buttons (1 being on the left - 6 to the end of the right) then pressing and releasing 6 - this did not fix it so we repeated but instead holding 2nd and 3rd. Can you help?:)
