A:Answer We recently moved from a single family home to a two-level condo. Our laundry room is extremely small, forcing us to stack our washer and dryer. We ended up acquiring a small washer and dryer made by Bosch. We bought the 300-series line for both as the 500-series line is similar but more costly, The Bosch dryer is self-contained, meaning that there is no need for external venting as the machine uses a water-based drying system, thus eliminating the need to clean the external air filter tube periodically to reduce the possibility of a lint based fire. I cannot directly answer the question posed, but do recommend the 1-800 Bosch information line (1-800-944-2904) for these types of questions. We have used it several times, and highly recommend it. Note: If you do parchase the 300-series line, be advised that the doors on each machine open/close in different directions, and are non-reversible.
