Fit notes

- Body width 23.5" must clear your door frame, not just the closet.
- Door swings out to 42.5" deep — leave room to open it.
- Runs on a standard 120V outlet.
- Ventless — no exhaust duct needed per the manufacturer.
- Uses a faucet adapter — no permanent drain hookup required.
Note: TWB120WP is discontinued/no-longer-available for new orders at AJ Madison as of access date (replaced in that retailer's catalog by Miele TXD160WP); however, TWB120WP is the model documented in Miele USA's official current T1 Ventless Heat Pump Dryer spec sheet, and AJ Madison's product page (Miele Classic T1 Series listing) confirms the 120V/15A rating and dimensions independently. Retained TWB120WP as the primary record per task's named target; note that a shopper today would be steered to TXD160WP (~$1,899) as the in-stock equivalent.

| Extended terms | Retailer spec table (AJ Madison) lists Miele parts & labor warranty as 1 year for this model. A separate tooltip on the same page states Miele appliances are backed by a 'two year warranty,' pointing to mieleusa.com — that Miele page loaded only site navigation (no term text) when fetched, so the exact current duration (1 vs 2 years) could not be independently confirmed on Miele's own site. Treat term as uncertain. |

Recurring praise
- Owners switching from vented or older European-style units liked that this dryer fits tight laundry closets and runs on a standard 120V household outlet rather than requiring 220V. — theme from AJ Madison - Miele TWB120WP customer reviews reviews, accessed 2026-07-10
- A long-term owner in a humid coastal climate was pleasantly surprised the heat-pump technology dried clothes effectively, with extracted moisture collected in an easy-to-empty reservoir. — theme from AJ Madison - Miele TWB120WP customer reviews reviews, accessed 2026-07-10
Recurring complaints
- Multiple owners describe the internal water pump failing more than once, sometimes leading to frustrating service scheduling and repair-cost disputes with Miele support. — theme from AJ Madison - Miele TWB120WP customer review reviews, accessed 2026-07-10
- Some reviewers report the dryer running very hot and heating up the surrounding room, with cycles that can stretch to a couple of hours while clothes stay noticeably warm afterward. — theme from AJ Madison - Miele TWB120WP customer review reviews, accessed 2026-07-10
- One reviewer felt drying performance was inconsistent, saying a cycle could run several hours and still leave items damp, and found the drum too small for more than a couple of items at once. — theme from AJ Madison - Miele TWB120WP customer review reviews, accessed 2026-07-10
