Writing of purge valve

Good day. I have a problem with Agilent binary pump.

Pump sensor is red and i have postated that error.

Writing of purge valve tag failed.

When i push on Chemstation promgram purge then sensor is yellow and pump not ready.

I have a second error primary air removal, defill tuning.

I took off purge valve and clean this, but it still not work. I think that the problem is in purga valve motor. But i dont now how i chek it. Maybe you can get advice, what i need to do in this situation.
