Hi Jane

My cook key has been replaced and been using for the past 3-4 days and so far so good!

I would love to know the solution also as this happens to me constantly and is annoying when you need to continually go through the set up screen - almost everytime I turn the machine on.


Happy cooking sharyn hopkins.

Hi ladies,

I'm wondering if anyone else maybe having the same issue as I and if you have a solution.

When I remove the jug or replace the jug or increase the blade speed on my TM5 my Cook key quite often ejects itself. Not a problem in regards to following the recipe but is in the instance that I then need to go through the safety screens to get back to the recipe screen. I have been caught a few times where I'm milling at speed 8-9 and unable to turn the speed dial down/off as the screen locks then goes to the safety screen once the cook key regains connection.

C/S advise to check the prongs connecting the Cook Key are not bent or uneven and ensure that the Cook Key was clean and connection not compromised - confirmed with them that all was clean & prongs were in good order.

C/S advise that it maybe a software problem, but my problem is that Thermomix only release 2 updates in a 12 month period! and advised me to sticky tape my Cook Key to my machine for more secure fitting ... not the solution I was after and concerned of the safety if I find I'm blending soup or hot liquid at a high speed and the Cook Key decided to eject ... a safety concern I feel.

Disappointed a better solution is not available as my TM is used on a daily basis and the interruption to my "quick" cooking processes is annoying.
