VERY EASY TURN OFF EQUIPMENT TAKE OFF SIX SCREWS REPLACE SPRING REPLACE GASKET INSERT SCREWS BACK. ALSO YOU CAN BUY A NEW VALVE AND REPLACE THE TOP ONLY ADD SILICONE TO THE GASKET. MAKE SURE EVERY THING IS CLEAN

Make sure that your automatic pool cleaner doesn't have an obstruction in the hose that might not immediately be visible. This could cause it to circulate in one end of the pool. Also, check the water pressure to ensure that it has enough force to travel the entire pool.

I have the same problem and the best solution is to repair/replace the hydro timer kit. It has inner gears that are plastic and wear down and doesn't rotate through the cycle of water flo that changes it's direction. I'm in the process of exhaustive repair and I'm going to replace the hydro timer - (inside part only) and then see what happens. Moving the gears did change it's moving patterns tho.

Remove the six screws from the side of the backup valve and remove the gear assembly and replace it with a new one.

Here is a copy of the users manual for these pool cleaners:

Your backup valve has probally gone bad. You just need to pull this out of the line and take it to a pool store and have the internal replaced. They will do this for just the price of the part in most places.
