You obviously have a finisher fitted to your machine and this code is the detection of the tray lift motor not working. You can reset it in service mode but check that the finisher has not been leant on (as this warps the top and the claws get caught) it may also be the sensor for the tray which is mounted on the rear side of the finisher and is a very fine line between sensing the tray and not and this may need moving slightly.

Yes, that is it..... The company I purchased the unit from sent a company they use for service out to my house (free of charge)and the finisher needed to be aligned because it was off from the movers who delivered it...It is a fantastic unit...very happy with it.
