F4 signal. What does this mean? - Asko W6461SS Front Load Washer

Hello,

Welcome to FixYa.

I can tell you on the Asko machines the "F4" indicates an error related to the thermistor.

Whether the thermistor is actually at fault is another matter. It may be a faulty wire connection, the thermistor has become dislodged from the bracket mounting it to the tub or yes indeed the thermistor may be at fault.

Here`s what to look for and what it does...

THERMISTOR
Part no. : 80 616 63
Resistance: 40-60K ohms
Room temperature: 68°-86° F (20-30° C)

The thermistor ( for temperature measurement ) is
located between the motor cradle and the holder.

The thermistor measures and controls the water temperature via a heating element. In the event of errors the heater is switched off and F4 displays if the thermistor short-circuits or is disconnected from the program control board or programmer.

**unplug the unit from the dryer or wall whichever applies to your situation...safety first**

If you are capable, remove the rear panel and top panel to ohm out the thermistor to verify if it is within` the values I provided...or perhaps it has dislodged from it`s position as I alluded to.

In the event you need a thermistor and you feel you can replace it yourself I`ll show you how...I do recommend calling in an authorized Asko service provider.

CHANGING THE THERMISTOR

1. Remove the top cover as mentioned
2. Remove the rear panel as mentioned
3. Remove the thermistor by pulling it out to the left.
4. Remove the thermistor header connector from the program control board.
5. Install the new thermistor by threading it through the hole between the cradle and holder.
6. Connect the thermistor to the program control board.
7. Replace the rear panel.
8. Replace the top cover. (Don't forget the two
star washers for the outer screws.)


Hope this helps move you forward or at least gives you an idea of what needs to be looked at.

Let me know if you require further assistance or this is not clear I can post pictures/illustrations. Thanks for choosing FixYa today.

Good luck.
