AEG F601 fault codewhat it means and how to fix it
One of four Wi-Fi codes on connected AEG ovens. None of them affects cooking, and AEG give all four an owner remedy rather than sending you to an engineer.
Before you start
What F601 means
Connected AEG ovens report network problems through four codes, and AEG define all of them in the manual and none of them on their website. They are worth taking together because the distinctions are fine and the remedies are almost identical. F601 means there is a problem with the Wi-Fi signal, and AEG send you to check your network connection. F602 and F603 share one entry meaning Wi-Fi is not available, cleared by turning the oven off and on.
F604 means the first connection to Wi-Fi failed, also cleared by turning the oven off and on, with AEG pointing you back at the wireless connection instructions in the Before First Use chapter. The important thing about the whole group is what they are not. These are codes about a radio link, not about an oven, and AEG place them in the table of problems an owner can handle rather than the table requiring a call-out. An oven showing any of the four will still cook.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Weak signal where the oven is installed | A built-in oven sits in a metal-lined cabinet in the middle of a kitchen, which is an unhelpful place to put a receiver. Distance to the router is the usual culprit. | Common |
| The router has changed, restarted or handed out a new address | A replaced broadband box or a changed password leaves the oven holding credentials for a network that no longer answers, which reads as unavailable. | Common |
| Initial setup did not complete | The specific meaning of F604. Pairing a connected oven is a multi-step process and it can fail partway without making that obvious at the appliance. | Occasional |
| The oven is being asked to join a 5GHz-only network | Connected appliances generally expect the 2.4GHz band, so a router advertising only the faster band gives an appliance nothing it can attach to. | Occasional |
What to try yourself
Check the network itself first, which is AEG’s own instruction for F601. Confirm other devices in the kitchen can reach the internet before you touch the oven.
Turn the oven off and on. This is AEG’s published remedy for F602, F603 and F604, and it is the whole of it.
If you are seeing F604, treat it as a setup that never finished rather than a connection that dropped, and run the pairing process again from the beginning using the Before First Use section of your manual.
Carry on cooking regardless. None of these four codes concerns the heating side of the appliance, and AEG classify all of them as owner-handled rather than service-only.
Get a qualified appliance engineer to look at your AEG F601
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.

- DemoUsually simple to fixThe oven lights up, accepts settings and never heats. AEG admit demo mode can switch itself on after a power cut, and the code to switch it off is 2 4 6 8.Related: controls and clock
- SAFEUsually simple to fixSAFE or a padlock symbol means one of three things on an AEG oven, and only one of them needs you to do anything. Work out which before you start pressing buttons.Related: controls and clock
- F113Get it checkedAEG name F113 as an example of a code you might see, then publish no meaning for it. It is one of roughly 74 oven F codes they list and do not define.Related: controls and clock
- F240Get it checkedThe touch controls are not registering properly. AEG class this as owner-fixable and their remedy is to clean the display, which is less dismissive than it sounds.Related: controls and clock
- F908Get it checkedThe oven cannot talk to its own control panel. AEG define this one in the manual and leave it out of the code list on their website, where it appears only as an example.Related: controls and clock
- LocUsually simple to fixThe function lock. It stops the temperature and timer being changed mid-cook, and unlike the child lock it can only be set while the oven is actually running.Related: controls and clock

Common questions about AEG F601
Which of the four codes do I actually have?
Read the display carefully, because they mean different things. F601 is a signal problem and points at your network. F602 and F603 both mean Wi-Fi is not available. F604 means the very first connection attempt failed, which is a setup problem rather than a dropout. AEG give F602, F603 and F604 the same remedy and F601 a different one.
Will a Wi-Fi code stop the oven cooking?
Nothing AEG publish suggests it will. These sit in the manual’s owner-fixable table, and AEG’s note on that table is that where a message persists the affected subsystem may be disabled while the rest of the oven functions continue to work as usual. On a connected oven the affected subsystem is the connectivity.
Why are none of these on AEG’s website?
The same reason most of the useful codes are not. AEG’s online table carries about 74 codes and defines none, while the manual carries about ten and defines all of them. All four Wi-Fi codes are in the second group, so the manual is the only place they exist.
