Drain error code 11

Please help. Receiving error code 11. Drain error. I tested the drain pump with both tester and rigged up to electric and operates. Cleaned out entire inside drain which was mostly clean. Took apart the drain valve. ball and inside was mostly clean. Test with tester showed good but not sure because there are 4 electrical connections. Two show good electric. Mushroom inside showed good when tested with electrical tester. All hoses clean. Only thing really left is the control panel unless the drain valve is bad. Went to parts store and tested new valve before purchase and it tested the same as old part so I believe that is good.
Please help. Any suggestions? Thank you.

I am not sure that I am reading the error properly but I think that the unit is looking for a valve open which would be that the position switch is closed so I would check the wires/connector going to the switch.
