i think whats happening here is there may be no movement of the lift( no use) and you might be getting a little leakage back into the tank. this will cause the lift drop a little but the relevel function maybe to close to floor level and not relevel properly which may trigger this 06 fault. if it runs on pencil readers i would extend the up(bottom) magnet longer(about 1/2 to 1 inch) to let the lift go more under floor level which may give it a more positive relevel. it certainly cant hurt the action anyway. ive had this on a spanish type we use.
