The Bosch 800 Series dishwasher has received mixed reviews for its drying capabilities, particularly regarding plastic items. While some users report that their dishes, including plastic, come out dry, others complain that their dishes are still wet, specifically mentioning issues with drying plastic items. Bosch dishwashers use a condensation drying system, which may not effectively dry thin plastics. However, Bosch recommends using rinse aids like Finish® Jet-Dry® or Finish® Turbo-Dry® to enhance the drying process for plastics. Additionally, some models offer an Extra Dry option and a Sanitize option, which increases the drying temperature to improve results.

What You'll Learn

The Bosch 800 series dries using condensation, not heat
The Bosch 800 series dishwasher dries using condensation, not heat. This is a common feature of modern dishwashers, and it is more hygienic and energy-efficient than drying with a heating element.
The condensation drying process involves a number of dishwashing elements working together to dry the dishes. The final rinse uses high-temperature water to make the dishes very hot. The stainless-steel tub of the dishwasher then cools faster than the dishes, causing moisture to condense on the tub walls and run down to the bottom.
While this process is effective for drying non-plastic dishes, some users have reported that plastic items do not dry well on the regular cycle. However, using a rinse aid or a product like Jet-Dry can improve the drying results for plastics. Additionally, the Bosch 800 series has an extra-dry cycle that can be used to dry plastic items.
The absence of a heating element in the Bosch 800 series also has the benefit of preventing plastic utensils and dishes from melting. Overall, while the condensation drying system may not be ideal for thin plastics, it is a safe and energy-efficient option for drying dishes in the Bosch 800 series dishwasher.

The extra-dry cycle setting helps dry plastic
The Bosch 800 Series dishwasher has a drying cycle, but it dries by condensation, not by heating like traditional American dishwashers. This is more energy-efficient and hygienic than drying with a heating element. However, some users have reported issues with drying, especially with plastic items.
Some Bosch 800 Series dishwashers also feature Crystal Dry technology, which uses heat produced by zeolite crystals stored in a chamber in the back. This is a more expensive option, but it is supposed to dry dishes without using extra energy, and it should dry plastics effectively. However, there have been some reports of issues with this system, including water intrusion into the zeolite chamber and a faulty fan motor.
Overall, while the Bosch 800 Series dishwasher may not be perfect when it comes to drying plastic items, using the extra-dry cycle setting and a rinse agent can help improve drying results. For those seeking even better drying performance, the Crystal Dry technology may be worth considering, despite its potential issues and higher cost.

Finish Jet-Dry and Finish Turbo-Dry help with regular and extra drying
The Bosch 800 Series dishwasher dries dishes using hot air distributed from a vent in the lower back side of the left side panel. This prevents spilled food or small plastic ware from falling on the element and burning. However, some users have reported that their dishes are still wet after a drying cycle. This is because the Bosch 800 Series dries by condensation, not by heating like some other dishwashers.
To improve drying, particularly for plastic items, it is recommended to use a rinse aid like Finish Jet-Dry or Finish Turbo-Dry. These products are rinse and dry aids that can be added to the rinse aid compartment of your dishwasher. They are surfactants, or surface-active agents, that help remove dirt, stains, and bad smells. They also contain a complexing/sequestering agent that binds to hard water and other minerals, allowing the cleaning agents to work more effectively.
Finish Jet-Dry and Finish Turbo-Dry can help with regular and extra drying. When used in conjunction with the Bosch 800 Series dishwasher, these products can improve drying performance, particularly for plastic items. While the dishwasher's condensation drying system may not completely dry thin plastics on the regular cycle, using a rinse aid can help improve results. Additionally, some users have reported that using the extra-dry cycle in combination with a rinse aid has successfully dried their plastic items.
It is important to note that while Finish Jet-Dry and Finish Turbo-Dry can enhance the drying process, the overall effectiveness may depend on various factors, including the hardness of your water, the amount of detergent used, and the specific model of your Bosch 800 Series dishwasher. For best results, it is recommended to follow the manufacturer's instructions for both the dishwasher and the rinse aid products. Additionally, as with any new product, it may take some experimentation to find the right combination that works best for your specific needs.

The drying cycle is not effective for thin plastics
The Bosch 800 Series dishwasher dries using hot air distributed from a vent in the lower back side of the left side panel. This prevents spilled food or small plastic ware from falling on the element and burning. However, this drying cycle is not effective for thin plastics. The dishwasher uses condensation drying, which involves a number of dishwashing elements working together to efficiently dry dishes. While this is more hygienic and energy-efficient than drying with a heating element, it can result in plastics not drying well.
One user reports that they need to wipe water off their plastics after a cycle, while another mentions that their plastic cups pond some water on top. Another user reports that their plastic items are completely wet after a cycle. To improve drying results for plastics, Bosch recommends Finish® Jet-Dry® for regular drying needs and Finish® Turbo-Dry® for extra drying assistance with plastics. Additionally, the Extra Dry option on select models adds extra heat to the final rinse to enhance drying results.
The Sanitize option on select models increases the time and temperature of the final rinse, which can also improve drying results. Leaving the dishwasher door ajar for a while before unloading can also help to evaporate residual moisture. While the Bosch 800 Series dishwasher may not dry thin plastics effectively on the regular cycle, these additional steps and settings can help improve drying results for plastics.

The Crystal Dry system dries dishes using heat produced by zeolite crystals
The Bosch 800 series dishwasher has been praised for being quiet, washing well, and accommodating different dishes. However, some users have reported issues with the drying function, especially when it comes to drying plastic items. Bosch dishwashers use condensation drying, which involves heating the final rinse water to a specific temperature, such as 150°F, and allowing the dishware to retain heat while the interior of the tub cools down faster. This process may not be as effective in drying certain types of plastic.
To address this issue, Bosch introduced a new feature called Crystal Dry, which utilizes zeolite crystals to enhance the drying process. Zeolite is a volcanic mineral that releases energy as heat when it comes into contact with water, and its highly porous structure allows it to absorb and store heat energy. In the Crystal Dry system, the zeolite crystals are heated during the dishwasher cycle, and the generated heat is used to dry the dishes.
The Crystal Dry technology is designed to deliver 60% better drying results compared to Bosch dishwashers with PureDry. It uses natural minerals to absorb moisture and transform it into heat, with temperatures reaching up to 176°F. The resulting hot air is circulated throughout the tub, effectively drying dishes and even plastics. This system eliminates the need for a heating element at the bottom of the dishwasher, preventing spilled food or small plastic items from burning.
While the Crystal Dry system offers improved drying performance, some users have encountered issues with water intrusion into the zeolite system due to cracked seals or a malfunctioning zeolite fan motor. These problems can be costly to repair and may require purchasing a new machine. Therefore, while the Crystal Dry system has the potential to improve the drying capabilities of the Bosch 800 series dishwasher, particularly for plastic items, it is not without its drawbacks and potential technical issues.
