What F13 actually means
The machine can no longer tell how hot the drying air is, so it has shut the drying side down.
F13 on an Ariston washer dryer points at the drying circuit's temperature sensing — the thermistor that monitors air temperature, or the fan that moves air past it. Because the control board cannot confirm the air temperature is safe, it will not switch the dryer element on, so the cycle either refuses to dry or abandons drying part way through and leaves the load damp. Washing itself is usually unaffected, which is why owners often report "it washes fine but won't dry".
What F13 looks like on a Ariston washer dryer
Most people find this page having searched for what the machine is doing rather than the code itself. On a Ariston washer dryer, F13 usually shows up as one or more of these:
- Machine not draining
- Water left in the drum at the end of the cycle
- Stops mid-cycle full of water
- Standing water in the bottom
- Not drying
- Blowing cold air
- Clothes still damp at the end
- Takes hours to dry
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
- Faulty dryer thermistor (the air temperature sensor)
- Dryer fan not running or running slowly
- Loose or corroded connection in the drying circuit
- Failed control board driving the drying circuit
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 for a minute, then power it back up and try a short drying programme — the odd one-off sensor reading will clear.
- Clean out the pump filter at the bottom front; a slow drain can upset the end of the cycle and it needs doing anyway.
- Try drying a much smaller load — a drum packed tight restricts airflow past the sensor.
- Make sure the machine has some breathing space and the room is not stiflingly hot, as drying relies on drawing in cooler air.
