LG F14A8RD Washer Dryer: CD Error During Drying Cycle and Door Lock Issue

Hello.
Why in the option of drying without spinning about 30 minutes at the very end there is a CD error and does not open the door. However, after turning the knob from the dryer, the device turns off and the lock clicks, i.e. it opens. I couldn't find this error anywhere. The washer dryer has a load of 6/3 kg.

I would still have a request to remove this washing machine from the top without a hatch. The dryer is probably not connected properly. I can't find this washing machine anywhere without a cover.

CD - an error occurred in the inverter module

Hello,
I have a similar one in the new LG F2DV5S8S1 washer-dryer. Mainly for drying or drying plus a short wash.
I can see that the post from 2019 ... Was there a solution to this ??

I already know! Cooling down after drying can be interrupted by any button! ? And there is nothing in the manual about it ...
