Unfortunatly you have a bad circut board. Which is very expensive. One good thing though, you will upgrade the unit when doing so.

SOURCE: Pool pump will not fill back up

It sounds like you are sucking air into the pump. Make sure strainer baskets and pump baskets are clear, and the valves are in the right position. Also check the water level in the pool, and make sure that the pump is not sucking the skimmer dry. Next try lubricating the gasket on the pump lid, or if it is in bad shape (flattened/cracking) replace it. If this does not solve the problem put silicone around the inlet to the pump (silicone is a temporary fix that could last days or months--for best results replumb with teflon tape and sealant). If all that fails you could have debris stuck in the impeller.

SOURCE: Back pressure at inlet when pump is turned off

There is a check valve in the output side -- sounds like this valve is jammed, clooged or broken. If the valve is not visible as a separate fitting, it's in the line, probably in an elbow.

SOURCE: I cannot get the pump to pump water, motor still works.

Sounds like air has gotten into the pump and froze the pump. It will need to be replaced due to that reason. You can get a repair kit for the pump but it will not be gaurenteed to work

SOURCE: No water coming out when I backwash. I cleaned

water level must be about the discharge (eyeball) in the pool to back wash. Check the hose connections to make sure that hoses off the the filer head are going to the right place Look for the words "Pump" , "pool" and "waste" molded into the valve. I've seen it a number of times where "Pump" and "pool" were connected the wrong way.
