About the Smeg SO4302M1X

The Smeg SO4302M1X is a 45 cm compact built-in oven with a microwave, from the Classic range in fingerproof brushed stainless steel with Eclipse glass and a stainless Classic handle. It suits a kitchen adding a second oven or an eye-level combination microwave, and it brings Vapor Clean, a four-pane door and soft-closing hinges to the Classic look.

Cooking

There are 11 cooking functions: seven conventional (static, fan assisted, circulaire, ECO, large grill, base heat and pizza) and four microwave modes at up to 800 W (microwave alone, with top and bottom heat and the fan, with circulaire and the fan, and with the grill). Defrost by time, proving and a Sabbath mode are included, the last certified by the Federation of Synagogues, Smeg says. Stone cooking, BBQ and Air-Fry programmes work with Smeg's optional gourmet cooking stone, reversible BBQ plate and air-fry tray. The grill is rated at 1750 W, the circular element at 1400 W and the lower element at 1200 W. Temperatures run from 25 °C to 250 °C, and Smeg says the electronic control holds them within 2–3 °C.

Controls and everyday use

Two Classic knobs work with touch buttons and an EvoScreen LCD display. You can delay the start or set an automatic end, run the minute minder, keep food warm, lock the controls and adjust the brightness and tones. Rapid pre-heat shortens warm-up by up to 50%, according to Smeg.

  • Vapor Clean, plus an easy clean enamel cavity with 2 shelf positions
  • Quadruple-glazed door on Soft Close and Soft Open hinges
  • Two 40 W halogen lights that come on with the door open
  • Supplied with a chrome shelf, a grill mesh and a glass tray

Size and installation

It measures 454 x 597 x 548 mm (H x W x D) and weighs 35.6 kg. It fits a niche 445–447 mm high, 560–568 mm wide and at least 560 mm deep, in a column or under a worktop; in a column, Smeg asks for 35–40 mm of space at the top and back. It has no plug and should be wired in by an electrician, rated at 3300 W and 15 A on 220-240 V, with a 150 cm cable.

Frequently asked questions

What size niche does the Smeg SO4302M1X need?

445–447 mm high, 560–568 mm wide and at least 560 mm deep, in a tall column or under a worktop.

Are the Air-Fry, BBQ and stone accessories included?

No. The programmes are built in, but the air-fry tray, reversible BBQ plate and gourmet cooking stone are sold separately.

How does Vapor Clean work?

Put some water with a drop of detergent in the dip in the oven floor and run the programme; the steam softens burnt-on food so it wipes away.

Does it need an electrician?

Yes. There is no plug, and at 3300 W and 15 A it must be wired in by a qualified electrician.
