Hi. My Bosch Avantixx 6 VarioPerfect WAE28366GB washing machine suddenly showed a symbol of a key on the display, and will now not start.

Hi Adewale,
Unfortunately you need to contact Bosch customer service. You shouldn't try to solve by your own, you can void your warranty.

How to open washing machine door that won open normally

Did you read the manual ?

Did you read the manual?

Door switch fault

Dont worry your machine is ok
the flashing key means your child lock is on, and has to be disengaged

What you need to do is press and hold the on/off button for approx 5 seconds This should turn the lock off.

I hope this was useful.

Sounds like have inadvertently activated the child lock. To deselect you need to press and hold the start button for approx 5 secs or until the key light goes out. Hope this helps, please let me know if this works or if you need further assistance.l

My Bosch Avantixx 6 VarioPerfect smells and therefore the washing smells.Any solutions?

Hello, welcome to FixYa.

The Key symbol means the lock has been activated some how.

On most bosch of your class this is how you work it on & off.

Here`s how to deactivate it...

1) Press the "menu" button until you see "CHILD LOCK :ON" appear in the display. ( if nothing is pressed within 10 sec.following this the menu will close and it will default to program in the display )

2) Once you see what I just mentioned in the display press the "select" button until "CHILD LOCK :OFF" appears in the display.

3) Finally by pressing the "start/pause" button the key symbol should disappear confirming you have successfully exited the child lock program.

Let me know if this was helpful to you or not, if so please take a second and rate it accordingly.

Thank you for visiting "fixya" for your washer solution inquiry.

good luck going forward.
