Polaris Polaris VRX iQ+ Robotic Pool Cleaner with iAquaLink APP-CONNECT Error Fix: iAquaLink App Cannot Connect (iQ Models)

Error code APP-CONNECT on the Polaris Polaris VRX iQ+ Robotic Pool Cleaner with iAquaLink means: iAquaLink App Cannot Connect (iQ Models). The iAquaLink mobile app cannot connect to or communicate with the robotic cleaner. This applies only to iQ-enabled models (P965iQ, VRX iQ+, Alpha iQ+): (1) WiFi range — the PSU must be within range of your home WiFi router. The PSU connects to WiFi and relays commands to the cleaner. If the PSU is in a pool equipment enclosure far from the house, the signal may be too weak. Consider a WiFi range extender. (2) WiFi network — ensure the PSU is connected to a 2.4GHz network (not 5GHz). Many pool equipment controllers only support 2.4GHz. (3) Power cycle — unplug the PSU for 30 seconds, then replug. The WiFi module may need a reset. (4) App update — ensure the iAquaLink app is updated to the latest version. (5) Re-pair the device — delete the cleaner from the app and re-add it following the setup wizard. (6) Router settings — some routers with client isolation or AP isolation enabled prevent IoT devices from communicating. Disable this setting.
