Disc-Read Failure
The Wii cannot read the game disc. Usually a dirty laser lens, sometimes a cracked ribbon cable on 2008 units.

02
Warning
51030
Channel-Load Failure
A downloaded channel fails to launch. Linked to corrupted NAND blocks after partial system updates.
03
Warning
32017
Connection Drop
Online service drops mid-session. DNS, MTU, or a stale router lease — almost never the Wii itself.
04
Critical
0002
Boot Halt
The console halts before the health screen. Rare — almost always points to a Bluetooth module fault.

Every Wii error falls into one of these five families
Codes cluster by where they're thrown — the disc drive, the Wi-Fi module, the NAND, the channel loader, or the sensor bar. Knowing the family tells you which fix path to open before you even read the first step.
Severity is rated against original hardware only — we don't downgrade a warning to "info" just because a soft reset makes it disappear. If the code indicates NAND or laser wear, it's flagged Critical even if the Wii still boots.
01
112 codes
Disc-read & media
The 002-XXXX family. Failures of the laser lens, ribbon cable, disc tray sensor, or media authentication. The most-searched category on the site.
002-5112 · 002-5432 · 002-6420

94 codes
Network & connection
The 32XXX family. DNS, MTU, WPA, friend-code handshakes, and the long tail of WiiConnect24 / Wii Shop cert issues after the 2019 shutdowns.
32004 · 32017 · 32200 · 32400

87 codes
Channel-load & eShop
The 51XXX family. Corrupted channels, save-data write failures, and the eShop migration codes that still surface on vWii units connected to a Wii U.
51030 · 51100 · 51200 · 51700
04
71 codes
Boot & system halt
The 0002–0999 range. Pre-health-screen freezes, NAND faults, and the rare Bluetooth module halts that most troubleshooting sites skip entirely.

118 codes
Sensor bar, controller & peripherals
Warnings thrown by the sensor bar, Wii Remote sync failures, classic-controller handshake issues, and Balance Board pairing drops.

Indexed error codes
Every error, warning, and status code the Wii, Wii Mini, and vWii have ever thrown — including the rare 0002 boot halts most sites skip.
Technician network
Volunteer techs across 12 countries running every fix against real hardware before it ships to the database.
Average time-to-fix
Measured across 1.1 million user sessions in 2024 — from the moment a code is typed to the moment the console returns to the health screen.
Resolved without a shop visit
Visitors who fix the console at home using the database — no shipping, no service ticket, no markup.
Cross-referenced with the official Nintendo repair manuals from the 2006, 2009, and 2012 firmware generations. Cited by iFixit, GameRevolution, and the r/WiiHelp subreddit moderators' pinned FAQ.
Narrow the database
Filter by console model, then by error family
The full 482-code catalog includes entries from four hardware variants — original Wii, Wii Mini, vWii on Wii U, and the Wii U eShop migration codes. Filter chips at the top of every catalog view let you keep only the entries that apply to your console.

Pick the error family
Disc-read, network, channel, boot, or peripherals — narrows the list to the family your code belongs to.
