Electrolux E91 tumble dryer: 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 E91 actually means

The dryer's two circuit boards have stopped talking to each other, so the machine cuts the cycle short.

Electrolux dryers use a main electronic board to run the drum, heater and sensors, and a separate control/display board behind the fascia where you select the programme. E91 means the main board sent a message and got no sensible reply from the control panel board. Because the machine can no longer trust what it is being told to do, it stops the cycle rather than carry on blind.

What E91 looks like on a Electrolux tumble dryer

Most people find this page having searched for what the machine is doing rather than the code itself. On a Electrolux tumble dryer, E91 usually shows up as one or more of these:

Not drying
Blowing cold air
Clothes still damp at the end
Takes hours to dry
No function at all
Dead — nothing lights up
Lights flashing and nothing happening
Programme won't start

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 one-off electronic glitch that clears on a power cycle
A loose or damaged wiring connection between the two boards
Faulty control/display board behind the programme selector
Faulty main electronic board
Boards that don't match each other 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 dryer off at the wall socket, leave it for a minute or two, then switch back on and try the programme again — Electrolux's own guidance is that if the code returns after this, it needs an engineer.
Check the plug is fully home in the socket and you're not running the dryer through a extension lead or adaptor.
