No experience with TCL brand but we had an integrated AEG washer and dryer for more than 16 years, imported from Europe. It worked flawlessly until the electronic panel had to be replaced but could not find a spare.
You just need to pay attention to the fact that it handles a smaller load for the drying cycle, usually 4 or 5 kilos instead of 8 kilos for the washing cycle.
Nowadays technology has changed, using the condenser process.
Beware of hard water; before being connected to PWA we were on a well and had to install a water softening installation.
