The E1 code would come up and switch back and forth between it and the cooking temperature for some reason. I switched it off for a few min and gave my pan a good scrub underneath. Also recleaned the surface and it worked fine after that. Its been working wonderfully for the last year so i wasnt sure why it did that. I know E1 comes up if you dont have a pan on the surface or a non magnetic one. Sometimes it just needs a reset. Don't panic!
Could low voltage of say around 100 to 120v make the cooker not to heat up red? Also could voltage fluctuation make the e1 or ea come up ? Can using a voltage stablizer solve these problems
check with multimeter the wavy element (big circle ceramic) if it wavy element burnt / corrosion / broken in the middle . there's should be a connection from both ends
