Electrolux C03 oven: what it means & what to check

Stop using it for now. Carrying on with this fault risks further damage or a leak. Switch it off at the wall until it has been looked at.

What C03 actually means

The oven has detected that the electricity coming into it is below the voltage it needs, so it has shut the heating off.

The control board constantly monitors the mains supply. When the incoming voltage drops below the level the oven needs to work safely, it stops the heating elements and shows C03. It's either a genuine problem with the supply to the oven, or the board is misreading it because of a poor connection or a fault on the board itself.

What C03 looks like on a Electrolux oven

Most people find this page having searched for what the machine is doing rather than the code itself. On a Electrolux oven, C03 usually shows up as one or more of these:

Not heating up
Takes ages to get to temperature
Cuts out part way through cooking
No function at all
Dead — nothing lights up
Lights flashing and nothing happening
Programme won't start
Oven tripping the electrics

Recognise any of those? That is this fault, and the rest of this page explains what causes it and what you can check yourself.

What usually causes it

Low or unstable mains voltage in the house, or a supply dip
Loose or poor connection in the oven's power supply
Overloaded circuit or a shared socket dropping voltage under load
Faulty power board misreading the supply

What you can safely check yourself

Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.

Turn the oven off at the wall for a minute, then back on, and see if the code clears
Check whether other appliances on the same circuit are behaving oddly or lights are dimming — that points to a house supply issue rather than the oven
If the oven is plugged into an extension lead or adaptor, use a proper wall socket instead
Try the oven when fewer heavy appliances (kettle, shower, tumble dryer) are running

Which Electrolux models show C03

C03 means the same thing on all 2 of these models. If yours is not listed, the explanation above still applies — the code is set by the control board, not the model number.
