Fix Netflix Error UI-800-3: Clear Device Cache And App Data (2025)
Updated: 11/29/2025
You open Netflix on your TV or streaming stick, hit play, and instead of your profile or shows you get Error UI-800-3. The app may say Netflix has encountered an error or simply refuse to load the home screen at all. This specific error means your device is holding on to old or corrupted Netflix data and needs its cache refreshed before streaming will work again [web:103][web:104][web:107][web:110][web:119].

Method 1: Power Cycle Your Streaming Device
The official Netflix guidance for UI-800-3 starts with a full power cycle, because a quick on off from the remote does not always clear stuck app data from memory [web:103][web:107][web:110].
Step 1: Shut The Device Down Completely
Exit Netflix, then turn the TV, console, or streaming stick fully off using the system power menu rather than just backing out of the app. If your device has a dedicated power plug or switch, use that so it stops drawing power entirely [web:103][web:107].
Step 2: Unplug From Power And Wait
Disconnect the streaming device and TV from the wall outlet or power strip and leave them unplugged for at least one to three minutes. This wait lets capacitors discharge so temporary data in memory that might be causing UI-800-3 is really cleared [web:107][web:110].
Step 3: Plug Back In And Test Netflix Again
Reconnect everything, power your TV and device back on, open Netflix, and sign in if prompted, then try loading your profile and playing a short video. If UI-800-3 no longer appears after this deep restart, the issue was likely just cached app data in RAM on the device [web:103][web:110][web:119].
Method 2: Refresh Your Netflix Account Session
If you suspect too many devices are logged in, open Netflix in a browser, go to your profile Account page, and choose Sign out of all devices. Wait a few minutes, then return to your problem device, sign in fresh, and try streaming again, this forces every client to rebuild clean sessions [web:110].
Method 3: Clear Netflix App Data Or Reinstall The App
On some TVs, especially when UI-800-3 appears alongside other network errors, you can improve stability by switching DNS to a reliable provider like your ISP default or a well known public DNS in the network settings. After saving DNS changes, restart the device and test Netflix again to see if the combination of clean app data and fresh DNS route cleared the error [web:110][web:119].
