Hyster H2.5FT

We have resealed all the lift cylinders but the mast is still dropping! It has electronic hoist controls

bad check valve or relief valve in the main control valve?

on these electronic controlled valves they usually have a lift solenoid and also a dump valve solenoid, could be one of those not seating closed completely allowing the leak down.
