It is bosch, possibly still under guarantee, will check. No problems till now, cooked porridge as usual this am then went to defrost frozen fruit, forgot to reduce power, but every day I defrost a few berries on low on a saucer. Spectacular flashing and burning. quickly reduced power, covered berries ad changed container. On low power one more bit of flashing. all the fruit tasted burnt. Racked our brains as to whether anything metallic had got it - but what on a clean dry plate? sigh, never not using it.
