SEBO ET-C1 Washer for ELECT...

Product details
The ET-C power head uses a washer of its own specification, catalogued by SEBO as the ET-C1 and supplied here as part 0155, one per order. It also serves the ELECTRONIC 370, which shares the same power-head architecture, and it is not one of the general chassis washers used elsewhere on SEBO machines.
Inside a power head the washer sits under a fastener in an assembly that is turning, loaded and constantly shaken by the brush roll, so a flat, undamaged bearing face is worth more here than almost anywhere else on the machine. A washer that has cupped, worn thin or picked up a burr lets its screw settle a fraction, clamping force drops away, and the bracket it was holding begins to move against the housing. That movement is what turns a five-minute washer change into a worn boss and a much longer repair.
The tell-tales are a power head that has developed a knock, a fixing that will not stay tight through a single job, or visible polishing where a bracket has been fretting. Ordering the ET-C1 by number takes the guesswork out of matching an unmarked washer by eye, which matters because a power head carries several similar-looking rings in different specifications. SEBO's own designation on this one, ET-C1, is the whole point: it identifies the washer by the assembly it belongs to rather than by a generic bore size.
