This is a $20 rice cooker from Taobao which stopped working with an E1 error just when we had family over for dinner.
Starting from the bottom (which was the wrong side).
But pulled it all apart anyway. It’s actually quite a tidy unit.
Bottom looked ok so trying the lid now which was just held on with plastic tabs.
Ah, here is the culprit. Looks like the ribbon broke from fatigue.
Soldered it back and checking for continuity.
Wrapped back up in the heat-shield housing.
