I hated those heaters. The most common failure point. Made a lot of money selling them, though :D And replacing the pump/heater assembly on a Bosch/Siemens is harder than on Indesit/Beko/Whirlpool. Have to fiddle with a screwdriver and a flashlight from the side. On that note, the drainage needs cleaning often (or the sensor whines about it), and I liked the water flow sensor (which they use instead of a pressure switch) on Bosch/Siemens.
