Help! Pump problems

[kevinm]

Auto and service are settings on the pool controller - auto allows the computer to control everything and service let's you control from the panel at the pump and filter.

Opening the pressure valve on the filter is how I originally got it to prime the first time.

Is it possible that there is a blockage on the suction side? It's a 2" supply so I can't imagine it's blocked. Also, I can't get it to prime on pool or spa setting, and I can't believe both lines could be blocked. Spa setting has both suction and return set to for the spa.

I disassembled the pump - thinking that I re-assembled it incorrectly.

I also have a spigot after the pump and before the filter. I've even opened it with no luck. So that would indicate it's not on the pressure/return side.

Thanks for the thoughts.

This morning I disassembled the pump, everything looked fine, so I reassembled. I also confirmed there was no obstructions in the line. I then re-siliconed the o-ring on the basket lid, filled up the basket and re-tightened the lid. I started it up still would not prime. Shut it down, switched to spa mode, tried it again and to my disbelief it primed. So, I let it run a little while, switched to pool mode, and it continued to work. I've not yet shut it off to see if it will re-start as I need to get the pool clean.

Hopefully, all is now well.

Thanks,

Interesting thing to note when you shut it off if the water drains out of the pump basket. If it does then there is an air leak somewhere. When running in 'pool' mode do you notice any air bubbles shooting out the returns?

Well, everything worked fine up until yesterday. Then, pump lost prime. Now, it won't prime again. I put in all new seals today with silicone lubricant, confirmed no obstructions in the lines, still won't prime.

I'm at a loss any thoughts?

Thanks,
Kevin
