I have a Jandy Aquapure 1400 that hasn't worked in over a year. Last summer I added chlorine manually because I didn't have time to troubleshoot it (I'm working away from home). The unit beeps about every two minutes and has a service light on. The error code is 170 which the manual says is a "possible front board servic condition" or incorrect wiring. The latter has never changed so it seems unlikely, but I have no idea what the former means. Does anyone here? The unit is actually turned off because the water is too cold. There's also what looks like a "Jo" code, but that's not in the manual. Any ideas? You guys just solved my pump wiring problem so I thought I give this a shot. Sounds like no one else here uses the Jandy. Thanks.
