Water is warmed as it passes through, then pumped out to the spray arms. That means one part covers two jobs, and a failure can show up in two ways. If the heater side fails, dishes come out cold and greasy, the cycle runs far longer than normal, or a heating fault is shown. If the pump side fails, you may hear humming or grinding with little or no spray, and dishes stay dirty. A heater fault can also trip the safety switch.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Bosch part 12019637\u003c\/li\u003e\n\u003cli\u003eCirculation pump with built in heater\u003c\/li\u003e\n\u003cli\u003eListed for Bosch SMS, SMU, SMI, SMV and SPU models plus Siemens SN26M dishwashers\u003c\/li\u003e\n\u003cli\u003eModels are listed with production index, for example SMS50M22AU\/01\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFitting the heat pump\u003c\/h2\u003e\n\u003cp\u003eUnplug the dishwasher at the wall and shut off the water tap.
