I have a Jandy LXi400 heater that gives me a "FAULT - CHECK IGN CONTROL" when I turn on the heat. I've read a few threads and followed the troubleshooting guide (https://www.parts4heating.com/v/vspfiles/Troubleshooting/LXiTS.pdf) which led me straight to Step13. Rather than getting 24VAC at the...

My Jandy-PDA system is over 10 years old. I've already had the mainboard repaired (Bob @ BP Engineering). That repair lasted less than 6 months. It's failing in the same manner as before (randomly resets, sometimes won't POST/start, random devices running). Bob wants another $150 to repair it...

Hi, My Aqualink RS4 randomly powers off. Sometimes resetting the breaker brings it back to life, sometimes not. When it does come back it sometimes retains the programming but always forgets date/time etc. Equipment is about 12 years old. I've replaced the power distribution board previously...

Pool system has been running fine. Weekly check revealed no/low Cl levels. No errors on the equipment (though I did briefly see a 'service' light during the week). On inspection, my SWG electrodes have melted. Am I looking at a grounding issue somewhere on the equipment? I've shut...

I have an Aqualink RS4 with PDA connected to a small 1HP pump (water feature) and my main JEP 2.0 variable speed pump (runs the pool filter and switches to the spa). The RS4 has given me problems on and off in recent years. After resetting it (breaker) it will cycle through all the LEDs as if...

I needed to do a drain/fill (details in another thread). My original problem was very high Cu levels and because I had to do a simultaneous drain/fill (water table issues) I want to be sure I've diluted my original water enough. In testing my new water, the Cu levels appear to be around 1ppm...

Hi all, I've been managing my pool relatively successfully for the past few years, thanks in large part to the good folks on this forum. I've been testing my pH lately with an old kit that I left in the sun too long. Long story short, I allowed my pH to drop too low (below 6.0 according to my...

Hi, My pool is about 2 years old. I don't believe the SWG cell was ever calibrated as my local pool store consistently showed lower salt levels than was reported by my equipment. The equipment typically showed 3700ppm. The pool store (using test strips) showed 3200ppm and always recommend I add...

Hi, I have a newly installed Aqualink RS4 with PDA. The PCB has the capacity to run the filter pump and 3 aux relays. Currently they're wired to AUX1 - water feature pump (sheer descent) AUX2 - pool light AUX3 - spa light. I want to add some landscape lighting and have it hooked into my...

Hi, I'm a new owner of a new pool (2 months old) and a little out of my depth (no pun intended) with its' management. Chemistry this morning looked like: Free Cl : 0.0ppm Total Cl: 0.2ppm pH: 7.7 Hardness: 290ppm Alkalinity (w/ stabilizer correction): 96ppm CYA: 80ppm Salt: 2600ppm My biggest...
