I've had trouble twice in the last two weeks getting my pump to start up. I've learned, probably from TFP, that if the water level in my pool is too low that the pump won't prime (right term?). That definetly was the cause several months ago.
Two weeks ago when the pump wouldn't start up that probably was the case. Once again I was having trouble one night this week. I came out to test my water and the pump wasn't running even though there was still about 30 minutes left on the 8 hour run for the day. The pump light was lit on my control panel but nothing was going. The overflow from the spa was wet so it appeared the pump had been running earlier in the day. I turned the pump off and on by pushing the pump button on my control panel, nothing. I switched to service mode and tried gain, nothing.
Learning from past troubles I looked at the water line. It was definitely above the skimmer intake and maybe an inch below the overflow drain. The pump basket was pretty clean but I cleaned it out anyway. After that didn't solve the problem I added water right up to the overflow drain (about 25 minutes from my refill line on my irrigation system). The pump would not start up in service mode but when I switched to pool mode I was able to start up the pump.
If you review my other posts you will quickly conclude that I have no idea what I am doing. So maybe I just don't have an accurate sense of where the water line needs to be for the pump to work properly. But I'm still in my warranty period so if I do have a problem, or could have a problem, I want to get it addressed.
