Ah yes, it was heated! And it is the ultrasonic transducer in the stainless steel tank that is in question. As there is a plastic casing in the tank, the transducer being sandwiched, the plastic had started burning !!!
Moreover, on the main board, one notices a small transformer (which is connected by a cable to the transducer in the tank). Curiously, we clearly see that this transformer was welded HAND on the map (scratching the varnished largest welding ...)
Should we infer that this device has been repaired?
Or that the manufacturer has caught a component or design problem?
One thing is certain: the same is done for!
