Need install guide for bosch dishwasher model smu 2042 uc Need to know if it suppose to hook up to cold or hot water?

Hello again,



Sorry for the delay in my reply....I was driving to a service call.



Although the unit does incorporate a heating element for heating the water during wash and rinse, it is because even with a hot water supply the detergent`s require a much higher temp to activate the enzymes and other cleaning agents the machine may employ.



The issue with connecting to a cold water supply is the Bosch machine typically will heat water at a rate of 2°C per minute, if your water is only 50 -60 entering, it is going to take hours to complete a cycle.



That being said, cold water will also result in very poor pre-washing and the main wash will therefore suffer. So you can connect ot cold, it just isn`t recommended by the manufacturer...as it states in the installation guide.



Hope that help`s you understand better why the hot water hook-up is important and why the unit has the heating element. It is there to increase the water temp. not for drying. The drying is generally done via the ambient heat already provided by the wash cycle.



Good luck going forward.
