What F18 actually means
The oven's control board and the hob's control board have stopped talking to each other, so the oven shuts the heat off as a precaution.
On these Electrolux built-in ovens paired with a linked hob, the two boards exchange status messages constantly — the user interface expects regular confirmation of the oven's cooking status. If those messages stop arriving or aren't acknowledged, the interface cuts power to the oven board and shows the fault (often seen as F718 on the display rather than F18). Heating stops, and usually the display still lights up and buttons respond, which is why people assume the element has gone rather than a communication problem.
What F18 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, F18 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
- A loose or dislodged connection in the link between the hob and oven controls
- A momentary electrical glitch or supply interruption leaving the boards out of step
- Damaged or chafed interconnecting wiring behind the appliance
- A failed control or user interface board that has stopped responding
- A mismatched or incorrectly configured board after a previous repair
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 appliance off at the wall or trip its breaker for a minute, then power it back up — a genuine one-off communication dropout often clears and does not return.
- If the hob is linked to the oven, check the hob is switched on at its own control and not in a locked or standby state.
- Note whether the fault appears straight away on switch-on or only once cooking has been running — that's useful information for the engineer.
Which Electrolux models show F18
F18 means the same thing on this model. If yours is not listed, the explanation above still applies — the code is set by the control board, not the model number.

Can I fix Electrolux F18 myself?
There are 3 checks you can safely do yourself first.
- Turn the appliance off at the wall or trip its breaker for a minute, then power it back up — a genuine one-off communication dropout often clears and does not return.
- If the hob is linked to the oven, check the hob is switched on at its own control and not in a locked or standby state.

This one usually needs an engineer once you have tried them.
