New pump motor problem

[NCKevin]

I recently tried to start my pool for the season and found my pump would struggle once the lines were full. I bought a new pump motor. After wiring it up I'm unable to get it to prime. I replaced the seal on the cover over the basket, but it still won't prime. Any suggestions?

It seems that the engine can pump air or water intake is pipes become clogged. Test

The first Check that the sand filter is filled with water

The second Set selector to "recycle"

If the engine does not start so forget this advice, then I have misunderstood your description
