Jandy ePump Shows Offline Not Running

[GriffithJerryl]

I’m using RS4 controller with iAquaLink 2.0 to control Jandy ePump, Pro Series, Polaris Pool Sweep, 3 LED Lights and Deck Jets Valve. I Noticed this morning my Jandy ePump was not running with outside temp at 35. At this minute 8:01 AM the AquaLink air sensor is reporting 40 degree air temp. My Freeze Protect is set at 38 and has worked perfectly for 11 years. All other equipment referenced above is functioning perfectly normal at this minute. I noticed yesterday mid-afternoon when I was cleaning skimmer baskets the pump was not running. Fingers got too cold and forgot to check why ePump not running. I started doing some diagnostics earlier this morning when temp was 35. First thing I did put RS4 in Service Mode and pressed the ePump button and pump started to my relief. Then I went back to normal operation on RS4. Using the iAquaLink app selected the ePump start. The pump did not start but the RS4 display of Jandy AquaPure status lights displayed as if ePump was running. I then went back to Service Mode selected ePump and it did not start this time. I selected the Polaris Booster Pump and it started normal. I went back and forth between normal operating mode and Service Mode with selecting ePump with no success getting epump to start. I tried turning main breaker off few seconds then back on couple times with no success. ePump continued show Off Line. I waited a little while maybe 10 minutes, tried starting ePump in Service Mode and it started but seemed very low RPM’s and it didn’t do the Priming Cycle. I decided to start some research and few minutes later I went back to check the pump and it had shutdown on its own. About 7:45 AM I gave up doing diagnostics, set RS4 mode to normal operation, came inside to continue research. I can see my pool very well from inside. I have my program set to start ePump 8 AM and Polaris 8 AM. I left the RS4 in normal mode and To my surprise I noticed the ePump and Polaris had both started according to my program and I checked web AquaLink status and it’s showing me 2,750 RPM’s that set in the program to run concurrently with the Polaris. Then at 9 AM it’s set to go to 1,750 RPM’s. The ePump and Polaris are set to run until 9 AM. I was able to copy current status.

After running almost an hour the ePump shut down. Letting it rest another hour I put RS4 in Service Mode and tried to turn epump on and no response so I turned off the ePump since the Chlorine generator is on with no water flow which could likely destroy it. It’s only two years old since the Feb 14, 2021 below Zero and 20 inches snow split the Chlorine generator, three way valves and lots of PVC pipe and elbows.
To provide little more history on ePump “Off Line” status. In the 11 years I had the pump I’ve never seen Off Line status. I Live Rock AR and was visiting family in Wichita KS. I have 4 surveillance cameras, one covers the pool area that I use to check visual status of pool since was forecast 2 Degrees in LR Christmas week while we were in Wichita KS. Since I can control home lighting, thermostats, garage doors, security system, irrigation systems, doorbell visitors along with pool equipment I noticed ePump was in OffLine status a couple of those days we in KS. It never dawned on me that reporting Off Line the freeze stat setting does not work. I now have some leaks around the Sand Filter valve body and there was big block of ice built up at the Sand Filter valve assembly. I checked again from Wichita and operation was normal and all normal for week and half after returning home until yesterday afternoon. It’s a miracle I did not suffer enormous damage like I did Feb 14 2021 when negative 2 degrees with 20 inches of snow in Little Rock. It seems I have an intermittent problem that I HATE with passion. I’m guessing is some internal issue with the ePump electronic guts. Can the “bolt-on” electronic assembly be replaced or will the whole pump? Should I go ahead and order a replacement ePump? Looks like forecast mostly 40’s low except couple of days 34 tonight 37 Sunday night. Thanks for your help.

My first inkling is to suspect the RS485 cable that connects the pump to the AquaLink panel. If that is faulty then it would show ePump off line. What does concern me is when you went to service mode and the pump sometimes starts and other times not. That could be a faulty HP relay.

Letting it rest another hour I put RS4 in Service Mode and tried to turn epump on and no response so I turned off the ePump since the Chlorine generator is on with no water flow which could likely destroy it.

Your details show the AquaPure at 0% so the SWCG is off - regardless if flow is present or not. Double check your setting on the AquaPure button. Also, if your water temperature is below 52 degrees then the SWCG display will flash LO which also indicates the SWCG is Off.

For freezing weather, I do not depend on Freeze protection. I set my pump to run 24 hrs. (actually 23 hrs and 55 minutes software does not accept the same Start and Off time when setting a schedule).

Maybe @PoolGate or @ajw22 have additional ideas.
