Quick answer: PlayStation error codes use prefixes to identify the source: NW- (network errors — PSN connection, DNS, NAT type), CE- (console/application errors — game crash, corrupted data, storage), WS- (account errors — suspension, sign-in, payment), SU- (system update errors — download or installation failure). Check PSN server status at status.playstation.com before troubleshooting locally. Most NW- errors are fixed by restarting the router and fixing NAT type. Most CE- errors are fixed by rebuilding the database or reinstalling the game.
The CE-34878-0 That Appeared Every Time I Launched the Same Game
For three weeks, one specific game on my PS4 crashed with CE-34878-0 within five minutes of launching — every single time, at the same point in the opening cutscene. Every other game on the console worked perfectly. I assumed the disc was scratched, but the disc looked fine. I assumed the console was overheating, but the temperature was normal. I went to the PlayStation Support page for CE-34878-0 and found the fix listed third in the troubleshooting steps: delete the game’s saved data and reinstall. The game had a corrupted save file from a previous crash that was causing the new crash on every launch. Deleting the save and reinstalling resolved it immediately.
That experience taught me the most important thing about PlayStation error codes: the error code prefix tells you which system to troubleshoot, and the PlayStation Support page for that specific code lists the fixes in the order Sony has found most effective. Reading the support page before trying random fixes saves hours of unnecessary troubleshooting.
How PlayStation Error Codes Are Structured
PlayStation error codes follow a consistent format: a two-letter prefix identifying the system that generated the error, followed by a five-digit number identifying the specific fault, followed by a single check digit (example: CE-34878-0). The prefix is the most important part — it tells you immediately which system to troubleshoot. NW- codes are generated by the network stack (Wi-Fi, Ethernet, DNS, PSN authentication). CE- codes are generated by the console operating system or the application (game crash, file system error, disc read error, storage error). WS- codes are generated by PlayStation Network’s web services (account management, payment processing, content licensing). SU- codes are generated by the system software update process. E- codes are general system errors generated by the console firmware.
PS5 uses the same prefix system as PS4, with some additional codes specific to the PS5’s hardware (NVMe SSD storage, DualSense haptics, HDMI 2.1 output). Most CE- and NW- codes that appear on PS4 also appear on PS5 with the same meaning and the same fixes. When looking up a PlayStation error code, always specify whether you are on PS4 or PS5 — some codes have different causes on each platform.
The 5 PlayStation Error Code Categories
1. Network Errors (NW-) — PSN Connection, DNS, and NAT Type
NW- errors are the most common PlayStation error codes. They indicate that the console cannot connect to PlayStation Network, cannot resolve DNS, or cannot establish the type of network connection required for online gaming. Common NW- codes: NW-31194-8 (cannot connect to PSN — server or local network issue), NW-31250-1 (network connection timed out), NW-31246-6 (DNS error — cannot resolve PSN server addresses), NW-31291-6 (Wi-Fi connection unstable), NW-31453-6 (IP address conflict on the local network).
The first step for any NW- error is checking PSN server status at status.playstation.com. If PSN is degraded or down, no local fix will resolve the error. If PSN is operational, the issue is local: restart the router and modem (unplug both for 60 seconds, plug the modem in first, wait 30 seconds, then the router), reconnect the PlayStation to the network (Settings → Network → Set Up Internet Connection), and check NAT type (Settings → Network → View Connection Status). NAT Type 3 (Strict) blocks many PSN connections — enable UPnP in the router admin panel or set up port forwarding for PSN ports (TCP: 80, 443, 3478, 3479, 3480; UDP: 3478, 3479).
2. Application and Console Errors (CE-) — Game Crashes, Corrupted Data, and Storage
CE- errors are generated by the console operating system or by the application (game) itself. They cover a wide range of faults: game crashes (CE-34878-0 — the most common CE- code), corrupted game data (CE-36329-3), disc read errors (CE-30005-8), storage errors (CE-30002-5 — insufficient storage space), and hardware-related crashes (CE-34335-8 — system software error). CE- errors that occur in only one game point to that game’s data or a compatibility issue. CE- errors that occur across multiple games point to the console hardware or system software.
The most effective fix for persistent CE- errors is rebuilding the PS4/PS5 database: power off the console completely (hold the power button until the light goes out — do not use Rest Mode), then hold the power button again until you hear two beeps (approximately 7 seconds) to enter Safe Mode. Select option 5: Rebuild Database. This process reorganizes the console’s file system index without deleting any data — it takes 30 minutes to several hours depending on storage size. After rebuilding, test whether the CE- error recurs.
3. Account and Web Service Errors (WS-) — Suspension, Sign-In, and Payment
WS- errors are generated by PlayStation Network’s account management and web service systems. They indicate a problem with the PSN account itself, not with the console or the local network. Common WS- codes: WS-37368-7 (account temporarily suspended — Terms of Service violation), WS-37397-9 (cannot sign in to PSN — server issue or account problem), WS-36812-0 (payment method declined or expired), WS-37501-6 (PSN service temporarily unavailable).
WS- errors cannot be resolved by restarting the console or rebuilding the database — they require action on the account or on PSN’s servers. For WS-37368-7 (suspension), check the email address associated with the PSN account for a suspension notice. For WS-37397-9 (sign-in failure), check PSN server status first — this code appears during PSN outages. For WS-36812-0 (payment error), update the payment method in the PlayStation Store account settings. For persistent WS- errors not related to a suspension or payment issue, contact PlayStation Support at support.playstation.com.
4. System Update Errors (SU-) — Download and Installation Failures
SU- errors occur when the PlayStation system software update process fails. Common SU- codes: SU-30746-0 (update installation failed), SU-42118-6 (update file corrupted or incomplete), SU-30696-4 (update cannot be applied — storage issue). System software updates are required for continued access to PSN — a console running outdated system software cannot sign in to PSN.
For SU- errors, delete the failed update from Notifications → Downloads and re-download via Settings → System Software Update → Update Now. If the download fails repeatedly over the network, download the update file manually from the PlayStation website (playstation.com/en-us/support/hardware/) on a PC. Copy the file to a USB drive formatted as FAT32 or exFAT, in a folder named PS4/UPDATE (file: PS4UPDATE.PUP) or PS5/UPDATE (file: PS5UPDATE.PUP). Install via Safe Mode → Update System Software → Update from USB Storage Device.
5. Storage and Hardware Errors — Drive Failure, Disc Read, and System Faults
Storage and hardware errors indicate a fault in the console’s physical components — the internal storage drive, the disc drive, or the system hardware. CE-30005-8 indicates a disc read error or storage access error — the console cannot read the game disc or access the storage drive. CE-34335-8 indicates a system software error that may be caused by storage corruption or hardware failure. Repeated CE-34878-0 errors across multiple games (not just one) indicate RAM or storage hardware failure.
⚠️ Important note: Storage and hardware errors that persist after rebuilding the database and reinstalling the system software indicate a failing internal drive or hardware fault. On PS4, the internal hard drive is user-replaceable — a 2.5-inch SATA SSD (up to 2TB) can be installed following Sony’s official guide. On PS5, the internal SSD is not user-replaceable, but an M.2 NVMe expansion slot is available for additional storage. For hardware faults beyond storage, contact PlayStation Support — the console may be eligible for repair or replacement under warranty.
How to Fix PlayStation Error Codes: Step-by-Step
Step 1: Check PSN Server Status and the Error Code Support Page
Before attempting any local fix, check PSN server status at status.playstation.com. If any PSN service is degraded or down, wait for Sony to resolve the outage — no local fix will help. Also look up the specific error code on the PlayStation Support website (support.playstation.com) — Sony maintains a database of error codes with official troubleshooting steps. The support page for your specific code will tell you exactly which system generated the error and the recommended fix sequence.
Step 2: Restart the Console Completely
Perform a full power-off — not Rest Mode. Press the PS button on the controller, go to Power → Turn Off PS4/PS5. Wait 30 seconds after the light goes out completely, then press the power button to restart. Do not use Rest Mode for troubleshooting — Rest Mode maintains system state and does not clear the runtime errors that cause many CE- and NW- codes. After restarting, test whether the error recurs before proceeding to more involved fixes.
Step 3: Rebuild the Database (for CE- Errors)
For persistent CE- errors (game crashes, corrupted data, storage errors), rebuild the PS4/PS5 database. Power off the console completely. Hold the power button until you hear two beeps (approximately 7 seconds) to enter Safe Mode. Connect a DualShock 4 or DualSense controller via USB cable (Safe Mode does not support Bluetooth). Select option 5: Rebuild Database. The rebuild process reorganizes the file system index without deleting any data — games, saves, and settings are preserved. The process takes 30 minutes to several hours. After the rebuild, test the game that was generating the CE- error.
Step 4: Fix Network Configuration (for NW- Errors)
For NW- errors after confirming PSN is operational: restart the router and modem (unplug both for 60 seconds, plug the modem in first, wait 30 seconds, then the router). On the PlayStation, go to Settings → Network → Set Up Internet Connection and reconnect. After reconnecting, go to Settings → Network → View Connection Status and check the NAT type. NAT Type 1 (Open) and NAT Type 2 (Moderate) allow full PSN connectivity. NAT Type 3 (Strict) blocks many connections — enable UPnP in the router admin panel (typically at 192.168.1.1 or 192.168.0.1) to automatically open required ports. Use a wired Ethernet connection for the most reliable PSN connectivity.
Step 5: Reinstall the Game or Contact PlayStation Support
If the error persists after rebuilding the database and fixing the network, delete the game and reinstall it — your cloud saves are preserved if PlayStation Plus is active (Settings → Application Saved Data Management → Saved Data in Online Storage → Download to System Storage after reinstalling). For hardware errors (CE-30005-8 disc read error, repeated CE-34878-0 across multiple games), contact PlayStation Support at support.playstation.com — the console may require a drive replacement or hardware repair. Check whether the console is still under the standard one-year warranty or an extended warranty before paying for out-of-warranty repair.

Note: PS4 internal hard drives are user-replaceable with a standard 2.5-inch SATA SSD (up to 2TB) — follow Sony’s official replacement guide. PS5 internal SSD is not user-replaceable, but an M.2 NVMe expansion slot is available. For hardware faults beyond storage, contact PlayStation Support at support.playstation.com — check warranty status before authorizing out-of-warranty repair.
Conclusion: PlayStation Error Codes Are Easier to Fix Than They Look
The CE-34878-0 that crashed my game every five minutes for three weeks was caused by a corrupted save file — a fix that took less than 10 minutes once I found it on the PlayStation Support page. That is the pattern with PlayStation error codes: the fix is almost always documented, and the PlayStation Support website lists the fixes in the order Sony has found most effective. Reading the support page for the specific code before trying random fixes is the single most time-saving step in PlayStation troubleshooting.
PlayStation error codes divide into clear categories with distinct fix paths. NW- network errors start with PSN server status and router configuration. CE- application errors start with a game update check and database rebuild. WS- account errors start with the PSN account email and PlayStation Support. SU- update errors start with deleting the failed update and using the USB installation method. Hardware errors — persistent CE-30005-8, repeated CE-34878-0 across multiple games — require drive replacement or console repair.
The most effective preventive measure for PlayStation error codes is keeping the system software updated, maintaining at least 100GB of free storage (the PS4 and PS5 require free space for game updates and system operations), and using a wired Ethernet connection for PSN. These three habits prevent the majority of NW-, CE-, and SU- errors that PlayStation users encounter.
