It’s pretty complicated for a kettle but it’s great seeing some basic appliances being repaired instead of tossed.
I tried the same with a low cost grill iron ( to make sandwiches 🥪). With back in my mind that I not would buy another one but fix this one once it should break. The hinge broke and a few tabs that hold oneside metal in place. I glued it but after two weeks the it broke on another place. Could not live without tosties, have now a newer bigger one…I’ve tried…
I think mechanical failure is different than an electrical failure. Plastic and metal breaking is harder to fix than the electrical for a grill, which shouldn’t be much more than a power cord, a resistor dial, a switch, and a heating element.
