The MEDS301BS is a 30-inch single steam-convection oven with a 2.8 cu ft cavity, 17 heating modes, and a removable 45 oz water tank rather than a plumbed water line. It draws 3,950 watts on a 240/208V, 20A circuit – a lighter circuit than Thermador’s standard double ovens, since it’s a single cavity.
One detail worth knowing for service calls: this model uses an Ecolytic Cleaning Program instead of the 2-Hour Self-Clean found on Thermador’s non-steam ovens. A customer expecting a traditional high-heat self-clean cycle and not seeing one isn’t describing a problem – that’s the documented cleaning method for this steam-capable cavity. Scale buildup in the steam generator or water path is the other steam-specific issue to check first in hard-water regions.

Most Common Issues on This Model
Removable water tank not seating correctly, triggering a low-water or fill problem
Steam generator or water line scaling up over time in hard-water areas
Ecolytic cleaning cycle not fully clearing residue - it is a lower-heat catalytic-style process, not a true self-clean burn
Door seal wear allowing steam to escape during Steam/Steam Convection modes
Multi-Point probe reading errors
