You count on your Bosch dishwasher to work well; however, it can be frustrating when you see an error code appear from time to time. One error code you might notice is Bosch dishwasher error code E19. What does this mean?
A Recirculation Error
This error code E19 usually means that there is something wrong with the recirculation valve in the heat exchanger. In some cases, it is called a drain valve. You should start checking elements to see what is wrong.
The Heat Exchanger is Patented Technology
The heat exchange unit in the Bosch dishwasher is installed behind the left wall of the cleaning chamber. It is responsible for providing cooler water to the dishwasher during the washing process.
Your Dishwasher Can Use Cold Water
Because of this technology, you do not have to use hot water to feed your dishwasher. You can use cold water and rely on this part to heat the water up. This could save you money, reducing your energy consumption.

Addressing a Bosch Dishwasher Error Code E19
