Beko E31 fridge freezer: what it means & what to check

What E31 actually means

The main control board has lost contact with the small sensor board that runs Beko's Cool On Demand feature.

On models fitted with Cool On Demand, a separate sensor board reports back to the main control. E31 means those two boards have stopped talking to each other, so the fridge flags a communication fault. Cooling itself is often still running, but the feature that depends on that board won't work properly and the code will keep showing until the link is restored.

What E31 looks like on a Beko fridge freezer

Most people find this page having searched for what the machine is doing rather than the code itself. On a Beko fridge freezer, E31 usually shows up as one or more of these:

Not cooling
Freezer not freezing
Ice building up at the back
Food going off in the fridge
Running constantly and never getting cold
No function at all
Dead — nothing lights up
Lights flashing and nothing happening

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 partly unseated plug between the two boards
A damaged or chafed connecting lead inside the cabinet
A failed Cool On Demand sensor board
A fault on the main control board
Moisture or condensation around the board connections

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 for a minute, then back on — an occasional communication glitch clears on a restart
Check the temperature readings and whether food is still cold and frozen, so you can tell the engineer whether cooling is affected
Make sure the doors are closing fully and the appliance isn't jammed tight against a wall, so it isn't running hotter than normal while you wait
