Bosch dishwasher shu4322 has code 1 aqua sensor what is the sensor do and where is it located
Most of the dishwasher has a Thermal hold period in which the machine will not advance to the next cycle until the water temperature reaches a specific degree. it is possible that your aqwa sensor/or heater is bad OR as in most of the cases, the Timer relay that is responsible in turning the heater on is stuck open, in this case you need a new timer. So,Check Timer/Aqua sensor/Heater
