How Does A Bosch Dishwasher Work?

Typically, Bosch dishwashers have sensors that detect your dishes and determine exactly how much water and power are needed to clean them. Bosch dishwashers use this information to conserve as much energy as possible while giving your dirty dishes a thorough clean.

Another interesting feature that many Bosch dishwashers have is the detergent sensor, which will tell you exactly how much detergent your load needs to get clean.

Do Bosch Dishwashers Use Hot Water?

Bosch dishwashers run primarily on cold water and then heat it during each cycle. Unlike other brands, Bosch appliances heat cold water to conserve energy and efficiently clean your dishes.

Of course, if you have a hot water line or solar heating system, you are fine to connect your dishwasher to them as well.

When it comes to locating the water heater on your Bosch dishwasher, you can find it inside the bottom of your appliance. Generally, Bosch dishwashers have a flow-through water heating design, which heats water gradually once the cleaning cycle begins.

How Hot Does A Bosch Dishwasher Get?

Typically, a Bosch dishwasher will heat to 130-150 degrees during a cycle. As we covered, Bosch appliances use sensors to determine how much energy and water a load needs, including how hot it will get.

With that said, Bosch heaters can reach temperatures as high as 161 degrees Fahrenheit, so you don't have to worry about your appliance not getting hot enough.

How Do I Adjust The Settings On A Bosch Dishwasher?

To change your dishwasher's settings, hold down its start button for three to five seconds. Doing this will reset it, allowing you to choose different settings for your dishwasher's cleaning and drying cycles.

Bosch dishwashers boast superior cleaning sensors and ability in their design, so troubleshooting shouldn't be super difficult. If you need help operating your dishwasher, you can always refer to Bosch's online care manual that covers just about everything you need to know.

What Is The Hottest Setting On A Bosch Dishwasher?

Heat-wise, the sanitizing setting on a Bosch dishwasher is its hottest mode. This setting reaches 155 degrees Fahrenheit and promises to kill 99.9% of the bacteria on your dishes.

Many Bosch users choose to run their dishes on this setting if they are sick or want an even deeper clean from their machine. That said, this hotter washing cycle does run longer than a regular wash and might run up your electric bill if done too often.

How Long Does A Bosch Dishwasher Cycle Take?

Generally, a Bosch dishwasher cycle will take close to two hours to complete. Even with its fastest setting being around an hour, Bosch dishwashers take time to heat their water and dry your dishes once they are clean.

Especially if your dishwasher senses a heavy load, this timeframe can reach up to three hours, so try to plan around it. Of course, not all cycles will take this long, but heavier, dirtier dishes will require a longer cleaning cycle.

What Is The Difference Between Auto Wash And Regular Wash On A Bosch Dishwasher?

Between the two, auto wash on a Bosch dishwasher is better for hard-to-clean dishes than a regular cycle. Generally, the regular setting on your machine is good for everyday dishwashing, while the auto wash option is better for pots, pans, and super dirty dishes.

Like we covered, auto-sensing comes standard in Bosch dishwashers and is a great way to save energy, water and even tell you how much detergent you need to use.

How Do Bosch Dishwashers Dry Dishes?

Bosch dishwashers use a condensation drying process, which is different compared to a traditional heating cycle. Condensation drying takes longer than heat because it relies on how quickly your dish's moisture can fall to the bottom of your machine versus heat drying.

With that said, Bosch dishwashers do promise an efficient drying process and should get your dishes mostly dry by the end of their cycle.

Do Bosch Dishwashers Have A Heated Dry Cycle?

From what we found on Bosch's website, none of their machines use heat during their dry cycle. Like we covered above, Bosch uses condensation drying technology to increase efficiency.

Although heat will get your dishes to dry faster, it can melt plastic dishes and uses more power than condensation drying does.
