    Remove tray and see if sensor is working see if . you can use manual to accurate tray

    It is probably the fault of a failed pneumatic directional control valve,

    You exchanged the valve, or the piston?

    You are correct , there is no sensor on the wash up trays , many times my colleague would leave the trays off and the press would still go through the wash up cycle , what a mess , solvent everywhere !!! The press doesn't know if the trays are on or off
