DIAGNOSIS The brewer is stuck in initial setup mode because the 2.4GHz Wi-Fi network is likely blocked or the QR code process failed.
FIX Force a factory reset and try the QR setup again, but manually. Unplug the brewer. Hold the PROGRAM and STRENGTH buttons while plugging it back in until the screen flashes. Release the buttons. The screen will show "SET UP WI-FI" again. Open the Ninja app, tap "Add Brewer," and this time, tap "Enter Code Manually" instead of scanning. Enter the 6-digit alphanumeric code printed on the sticker inside the water reservoir door.
IF THAT DIDN'T WORK Your phone or home router might be causing the block. On your phone, turn OFF "Mobile Data" and connect ONLY to your 2.4GHz Wi-Fi network (not 5GHz). Temporarily disable any VPN or ad-blocker apps. Then repeat code entry process.
HEADS UP The brewer's Wi-Fi module is basic; it cannot connect to networks that require a secondary login portal (like hotels or some corporate networks). It needs a standard home Wi-Fi password.
