My Sebo X1 is running the up motor constantly. This results in it going up and then down so eventually it lays flat on the carpet and trips as its too low. If it is placed on a hard floor the up is contant and the height goes up/down/up/down. never stops.
I have stripped down and cleaned the sensor on the belt sensor unit from dust but no diffferent.
Looking for any diagnostic ideas before buying spare parts, (belt sensor unit, main pcb).
