SEBO Electronic Controller for C3.1 Canister

Motor power on a SEBO C3.1 is metered by the board catalogued as 6407ER. It reads the operator's input, regulates what reaches the motor, and then holds that level steady for as long as the machine is running.

One detail marks this part out from the controller assemblies used elsewhere in the SEBO canister range: it carries no switch of its own. The C3.1 takes its on/off command from a foot pedal ordered separately, 6005GW in white or 6005DR in red, and cord retraction runs from a second pedal again, 6006GW. Suction is trimmed from the handle, which SEBO supplies complete with its hose and dual controls as 8545AM. What 6407ER contributes is the electronics between those inputs and the motor, and nothing else.

Read the symptoms before ordering, because a worn control and a failed board look different in use. A board that has given up leaves the vacuum stuck at one power level whatever the control asks of it, drops out part-way through a room, or refuses to start while cord, pedal and outlet all test sound. A tired pedal instead gives a machine that plays dead until the pedal is worked, then behaves normally. Separating the two saves ordering electronics that were never the fault.
