Water Does Not Get Hot in My Bosch Dishwasher

Household Water Supply

• The water that enters the Bosch dishwasher is the same water that is used throughout the house, so if the water inside the dishwasher seems too low, the household temperature may be too low as well. The home water should be kept at 120 degrees Fahrenheit or more, which can be verified by checking the home water heater. Increase the water temperature as necessary at the water heater.

Hot Water Use

• Along with the home water temperature setting, the hot water use in the home may affect the dishwasher performance. If other appliances that use hot water are in use at the same time as the dishwasher, this may reduce the hot water supply to the unit. Wait to use the dishwasher at a time when no other appliances are in use. You might also run the water at the sink next to the dishwasher until it is hot before starting a wash cycle to send hot water directly into the machine.

Cycle Selection

• Various wash cycles use various water temperatures, so the problem may be as simple as selecting a different wash cycle. For example, the “Eco Option,” “Half Load Option” or “Express” wash cycles all use water below 120 degrees Fahrenheit. If dishes are not getting clean enough following these cycles, run a different cycle with warmer temperatures.

Service

• If all else fails, contact Bosch for assistance. The dishwasher heater may be broken, or there may be other repair issues that will require someone with professional expertise to identify and fix.
