Hotpoint F12 washing machine: 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 F12 actually means

The main control board and the display/control panel have stopped talking to each other, so the machine won't start.

On Hotpoint machines F12 is an electronic control fault — a communication failure between the main circuit board and the user interface board that carries the buttons and display. Because the machine can't confirm what you've selected, it refuses to begin the cycle, and often it looks dead or half-awake rather than showing an obvious mechanical problem. It's not a fault with the drum, pump or heater.

What F12 looks like on a Hotpoint washing machine

Most people find this page having searched for what the machine is doing rather than the code itself. On a Hotpoint washing machine, F12 usually shows up as one or more of these:

Not heating the water
Washing coming out cold
Cycle takes far longer than it should
Leaking
Water on the floor
Puddle underneath
Shuts itself down and won't restart
No function at all

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 corroded connector between the control board and the display panel
A failed main control board
A failed display/user interface board
Damp or a moisture-related short around the control area
A mains supply glitch or power surge that has upset the board

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 machine off at the wall socket, leave it for a minute, then switch back on — this clears the odd one-off glitch
Check the plug and socket are sound and the machine isn't running through a damaged extension lead
Make sure the machine isn't standing damp after a leak or a spill on the control panel
