PS5 and PS4 Error Codes Explained — What the Prefix Tells You
PlayStation error codes are grouped by prefix and that grouping is the fastest way to a fix. CE is the console, NW is your network, WS is Sony's end.
The short answer
PlayStation error code prefixes identify the subsystem: CE- errors are console-side, usually storage or a corrupted database and fixed by rebuilding the database in safe mode; NW- errors are network problems on your side, typically DNS or NAT; WS- errors are PlayStation Network service-side and cannot be fixed locally. Rebuilding the database from safe mode resolves the majority of CE- errors and does not delete games or saves.

PlayStation error codes are more helpful than they look because the prefix is a genuine category, not decoration. Learning three prefixes replaces most lookup.
The three prefixes
CE- — console side. Storage, database, corrupted install, system software. NW- — network on your side. DNS, NAT, router, connection. WS- — PlayStation Network services. Sony's end; you cannot fix it. There are others, but these three cover the overwhelming majority of what people actually encounter.
Step 1: Read the prefix
Before searching the full code, note the letters. A WS- error means checking the PSN status page and waiting. A CE- error means the console. An NW- error means your network. This alone eliminates most of the wrong turns.
Step 2: Rebuild the database
The most useful thing you can do to a PlayStation, and it fixes far more than the name implies — crashes, slow menus, games that will not launch, install errors, and a wide range of CE- codes.
Fully power off 1 min
Hold the power button until you hear a second beep, roughly seven seconds. The console must be fully off, not in rest mode.
Enter safe mode 30 sec
Hold the power button again until the second beep, then release. The console boots to safe mode.
Connect the controller with a cable 30 sec
Safe mode requires a wired controller. Bluetooth is disabled in this mode, which catches out a lot of people who assume the console has frozen.
Choose Rebuild Database 10 min to 2 hr
Option 5 on PS5. It scans the drive and builds a fresh index. Nothing is deleted. On a full drive this can take well over an hour — leave it alone and do not power off partway.
Do this before anything more drastic. It is genuinely non-destructive and it resolves a large share of console-side faults.
Step 3: Fix DNS and NAT type
For NW- codes and general connection instability.
Manual DNS often fixes slow downloads and intermittent connection errors that look like Sony's fault. In network settings, choose a manual setup and set DNS to 1.1.1.1 and 1.0.0.1, or 8.8.8.8 and 8.8.4.4. Leave everything else automatic.
NAT type should read 2. If it reads 3:
- Enable UPnP on your router first — that alone fixes most cases.
- If UPnP is off or unavailable, forward TCP 80, 443, 3478, 3479, 3480 and UDP 3478, 3479 to the console.
- Check for double NAT. Two routers in series means the inner one's port forwarding cannot work. Bridge the ISP box.
NAT type 1 is not a goal. Type 2 does everything you need and type 1 requires exposing the console directly.
Step 4: Clear the system cache properly
Safe mode has a Clear Cache option and it is worth running, but there is a more thorough version:
Power off completely, then unplug the power cable for at least twenty minutes. This drains residual charge and clears volatile caches that a normal power-off leaves intact. It sounds like folk remedy and it demonstrably resolves a class of display and HDMI handshake problems that nothing else touches.
The common codes
When the disc drive is the problem
Disc-related CE- errors on the disc PS5 have one cause that is worth knowing before you book a repair: the drive is unusually sensitive to the console being positioned at an angle or on a soft surface that blocks airflow.
Before assuming a hardware fault, stand the console properly on a hard flat surface, check the disc for fingerprints, and try a different disc to establish whether it is the drive or the media. A drive that reads one disc and not another is not a broken drive.
Key takeaways
Frequently asked questions
Does rebuilding the database delete anything?
No. Rebuilding scans the drive and creates a fresh index of everything on it — games, saves, screenshots and settings all remain. It is not a reset and it is not a format. The only cost is time: on a full drive it can take an hour or more, and the console must stay powered throughout. It is the single most useful maintenance action on a PlayStation and it fixes far more than people expect.
What does CE-108255-1 mean?
It is the generic 'an error has occurred' crash code and it deliberately tells you almost nothing. In practice it usually means a corrupted game installation or a database problem. The reliable sequence is: rebuild the database first, and if the same game keeps producing it, delete and reinstall that title specifically. If every game produces it, the drive or the system software is the suspect rather than any individual game.
How do I know if a WS- error is Sony's fault?
WS- errors are PlayStation Network service errors by definition, so they are almost always Sony's side. Check the PSN status page, which breaks out account management, gaming and social, PlayStation Store and PlayStation Video separately. If the relevant service shows an issue, no local troubleshooting will help. The exception is a WS- error that persists while services are healthy, which usually points at your account rather than the network.
Why is my NAT type 3 and does it matter?
NAT type 3 means your console cannot accept incoming connections, which breaks voice chat, makes matchmaking slow and prevents joining friends directly. Enabling UPnP on your router usually moves you to type 2, which is fine for essentially everything. Type 1 requires the console to be directly exposed to the internet and is not worth pursuing. If UPnP does not help, check whether you have two routers creating a double NAT.
Is safe mode dangerous?
Not if you pick the right option, and the menu is ordered roughly from safest to most destructive. Rebuild Database and Clear Cache are harmless. Update System Software is fine. The two to be careful with are Restore Default Settings, which wipes your configuration but keeps data, and Initialise PS5, which erases everything. Read the option before selecting it — they are adjacent in the list.
