  1. Newbie to the forum. I have a Gulf Coast Spa LX5000 circa 2006 purchased from a neighbour who was moving. He had just replaced the pump and some of the jets, I replaced the final 4 jets. Finally got a pad and electrical hooked up, cleaned it and filled it. While bringing it up to temperature it stopped heating and reported a Rh-Nf (no flow) error, yet there was water flowing. Cycling the power would get it heating again, but then would stop again. It seemed if I set the temperature to just a few degrees above the current temperature it would heat again and finally got it to 100F. We were able to use it a few times but randomly I found it again had a no-flow error. I removed the filters and also the strainer on the bottom of the tub because I noted the high speed flow was not as aggressive as I though it should be. I still had no-flow errors after that and no increase in flow. I also taped the shaft of the knife valve at the input to the pump case it was sucking air. I also made sure all the jets are open. Yesterday I found it had a P1-Er (pump 1 error). Cycling the power, the motor did not restart and it came up with the error again. I did some troubleshooting (I'm an electronics guy ex-farmboy mechanic type) I had a little pie shaped BeachComber tub from '92 till 2013 that I converted from air switches to PLC control and temperature control using an industrial PID temperature controller. I could not read any voltage to the motor, but then its not in an easy spot to get to and once I thought there was voltage there, but the motor wasn't making a sound so not the start capacitor.. maybe the thermal cut-out? I left the spa breaker off overnight. This morning the pump would operate again but cut out after about 2 minutes. The display still shows the motor as running but then reports a pump 1 error Observations: - The pump on high speed never seemed to have the power that my old BeachComber did, so I'm thinking there is an obstruction. I checked for debris at the input of the pump today and found none. - The Gecko controller monitors the motor current so I put it through the current learning mode again. On high speed it records 10.4 Amp and 3.7 Amps on low speed... the motor is 2HP and the plate reads 8.4 Amps and 2.4 Amps... so the motor is drawing more current than it should. - I attached my voltmeter with clips and observed the pump voltage goto zero when the spa pack reported the Pump 1 error. So I'm thinking there must be an issue within the pump, or a restriction between the output and the jets. So, I think this restriction is loading the motor causing it to overload and the current detection in the spa pack shuts OFF the motor and reports the error. So my question is, what should my next step be? I'm thinking pulling the pump apart and checking for debris inside. There is not much after the pump to cause an obstruction... What say ye?
  2. Ever since we opened our pool we have been trying to get the water clear and everything working properly. This is our 1st year opening it since it was new last year. It is an above ground pool with a jandy salt system chlorine generator. ( I think that is what it is called). The jandy reads " no flow". This is the only reading since we have plugged it in. I have cleaned the cell which then looked better but didn't change reading. Our filter flow would deteriorate after a couple days. We lubed the lid to the motor pot. Our pool person suggested we were probably losing prime. Sounds good but reading still says " no flow". Been shocking the pool and added a lot of salt and a couple things here and there to try and clear up the pool. My last guess for the Jandy is the flow switch part. Does that sound right ? I don't mind replacing it but I'm hoping thats the issue then. When we took it apart to bring in for the winter the back plastic top seems to be snapped a little. Doesn't really look like it would have any effect on anything since the paddle still moves inside and all looks like its in tact where it matters. Any ideas or tips I'd appreciate. We are frustrated and not really fond of the help from the pool place.
