A:Answer Hi k9erthlvr, thank you for your question. Yes, you can quickly open the door and add dishes at the beginning of the cycle. One recommendation is to clean the filter per the Use and Care Manual. Here is the link for the Manual:https://media3.bosch-home.com/Documents/9001411179_D.pdf. Another recommendation is to use FINISH® Machine Cleaner with 5X POWER ACTIONS once a month, or as soon as you notice build up in your dishwasher. Clean, freshen, and help maintain your dishwasher, while cleaning even the hidden parts.
