Will a Bosch dishwasher work without hot water?

Yes, according to Bosch, the dishwasher will work adequately without hot water. However, the manufacturer does not recommend connecting the appliance to a cold water line unless the homeowner has an eco-friendly water heating alternative such as a solar water heating system with a circulation line.

Suppose you are unsure of how to connect the dishwasher to your kitchen's plumbing system. Contact your local plumber for professional advice and assistance.

Do Bosch dishwashers dry with heat?

No, all Bosch dishwashers dry the dishes with the drying condensation method. Which utilizes several elements within the small appliance to dry the dishes. Condensation drying is more hygienic and uses less energy than the traditional drying method via a heating element at the bottom of the dishwasher.

Since the Bosch dishwashers do not use a heating element for drying, placing plastic dishes and utensils on the bottom rack is safe.

Condensation drying is an interesting process that uses high-temperature water for the final rinse to heat the dishes. The dishes start to dry when the water drips from the steaming dishes into the stainless steel bottom of the appliance and is drained from the dishwasher via drain tubes. To speed up the drying process, choose the extra-dry or sanitize options when you start your load.

The Bosch company suggests using Finish by Jet-Dry rinse aid to speed up the drying process. This product helps your dishes look flawless when you remove them from the dishwasher.

Finish works by lowering the surface tension of the water and allowing it to drip off of the dishes easily, which allows the dishes to dry much quicker. Also, Finish is great for preventing water spots on plastic dishes and utensils.

Bosch dishwasher maintenance

Bosch suggests a few simple yet effective protocols to ensure the dishwasher is always working at its best. Firstly, plan to use the Bosch dishwasher cleaner a few times a year to remove grease residues and prevent the appliance from clogging.

Set one box of Bosch dishwasher cleaner on the bottom of the empty dishwasher and run the most prolonged and hottest cycle to cleanse the dishwasher. For best results, implement this simple practice once per season. Consider adding a reminder to your Google calendar, so you don't forget!


Descaling is another essential maintenance procedure that removes hard water and lime buildup from the dishwashers' interior and connecting pipes.

To descale, make sure the dishwasher is empty. Then, run the longest and hottest wash cycle. After 30 minutes, place one box of descaler at the bottom of the dishwasher and allow it to finish the cycle. Next, run one wash cycle without any descaler or detergent, only plain water to thoroughly rinse the dishwasher.

To ensure that your dishwasher continues to work correctly, be sure to regularly clean and empty the filter every three to six months.  Cleaning the filter is relatively easy and does not require any specific cleaners or tools.

To begin, remove the lower dish rack and spray arm to locate the mesh filter. Lift the mesh filter by grasping the plastic knob. Wash the filter in the kitchen sink with dish soap and hot water to remove all debris. Then, place the filter back to the bottom of the dishwasher, put the spray arm and lower dish rack back in place.
