Overview
The Smeg DOSF6300X is a built-in-column electric double oven in the Classic range, finished in brushed, fingerproof stainless steel with Eclipse glass. Its exact model and EAN are verified on Smeg's UK product page.
It combines a 70-litre thermo-ventilated main cavity with a 35-litre static secondary cavity, providing 105 litres of combined net cooking space.
Cooking capacity and performance
The main oven has four functions: Circulaire fan cooking, ECO, large grill and fan grill. It also provides five shelf positions, making it the more capable cavity for roasting, baking and multi-level cooking.
The secondary oven also has four functions, comprising static cooking, ECO, small grill and large grill. Its two shelf positions and 35-litre capacity make it better suited to side dishes, smaller bakes, reheating and grilling than large family roasts.
Smeg specifies rapid pre-heating, with the product page stating that heating time can be reduced by up to 50%. Closed-door grilling is also supported, while the main cavity's fan-assisted cooking is useful when preparing food on multiple levels.
Controls and everyday usability
The control layout combines four rotary controls with touch buttons and an LED DigiScreen. The programmer provides a minute minder, programmed cooking and automatic end-of-cooking settings for the main oven.
Both cavities have removable doors and removable inner door glass, while the main oven has a full-glass inner door. Smeg also specifies tangential cooling and suspension of heating when the door is opened.
Included equipment comprises two chrome shelves, two grill meshes and two 40mm-deep enamelled trays. Telescopic guides are optional rather than included.
Cleaning and maintenance
The cavities use Smeg's Ever Clean easy-clean enamel, an acid-resistant lining designed to reduce grease adhesion. The removable inner glass and tilting grill arrangement on the secondary oven also help with access during cleaning.
This is not a pyrolytic or catalytic-cleaning oven. Cleaning remains manual, although the enamel lining and removable glass should make routine maintenance less demanding than on a basic untreated enamel interior.
Energy use and installation
The 70-litre main cavity is rated A and uses 0.80kWh per fan-forced cycle. The 35-litre secondary cavity is rated B and uses 0.84kWh per conventional cycle, so the two cavities do not share the same energy rating.
The oven measures 884mm high, 597mm wide and 570mm deep, and weighs 56.2kg. Smeg specifies a 4,800W nominal load at 220–240V and 21A, with no plug supplied, so installation requires a suitable electrical connection by a qualified installer.
Verdict
The is a spacious and versatile double oven whose strong point is the 70-litre fan-assisted main cavity, supported by five shelf positions, rapid pre-heating and useful timed cooking functions. The smaller oven adds genuine flexibility for side dishes and grilling rather than simply duplicating the main cavity.
Its compromises are clear: the secondary cavity is B-rated, cleaning is enamel-assisted rather than self-cleaning, and the appliance needs a substantial hard-wired electrical connection. It is best suited to households that value two usable cavities over premium features such as steam cooking, oven combination cooking or pyrolytic cleaning.
