If the lines on the pushrods line up as per the instructions inside the solenoid cover, and there is no excessive play in the rod (try shaking it side to side), then the overall geometry of the pedal/pushrod/damper lever is not correct. This would be a job for a piano technician. If you do get play in the pushrod (at the bottom of the solenoid), there are two gold coloured screws at the top andbottom of the solenoid which can be adjusted. They should be in a position where you just remove the play in the push rod. If the screws are too tight, the solenoid has to work overtime, which can cause overheating.
gher than edge line F when the loud pedal is fully depressed.)

Once everything is physically OK, you need to run the pedal calibration procedure from the Service Center. I have come across this several times, and every time it was down to the fact that the pedals haven't been re-calibrated after the lyre was re-attached.
