Miele Electronic Unit for Compact C1 / S4210 / S4212 Canisters

Dead canister, good motor? On the Compact C1 / S4000 platform that points to the electronic unit. Miele part 7322114 is the genuine 120 V control board (SCAE0 designation) that governs the on/off switching and rotary suction-power control on these vacuums. When it fails the machine typically won't start at all, cuts out intermittently, or stops responding to the power dial — and this board is the documented repair.

Models this electronic unit serves:

• Miele S4210 Carina and S4212 Polaris (the two models this board is most associated with)
• Miele Compact C1 canisters on the SCAE0 chassis
• Other Miele S4 / S4000 series canister vacuums

It directly replaces a long chain of earlier boards — 7322113, 7322111, 7322110, 6715491, 6715490 and 6237980 — so if your parts diagram shows any of those numbers, this is the current genuine substitute. The board itself is compact (about 88 g, dealer alternate SKU 590186, UPC 4002516034650) and ships new in Miele packaging.

Mains-voltage electronics are not the place for lookalike parts: the OEM board carries Miele's component spec and switching tolerances. As an authorized Miele dealer, evacuumsandmore.com sources this electronic unit through Miele's official parts channel, so what arrives is the genuine 7322114 board, ready to put a Compact C1 or S4 back into service.
