Tchibo Expert Milk

In short: Found the small Tchibo Esperto Latte because of lack of space optimal.
First machine, bought in August 2020. 6 months everything was OK. Then within a few weeks pressure loss at the milk frother and coffee was noticeably less hot. Finally smoke leakage and exchange in branch. Now in September 2021, the milk frother of the exchange unit loses pressure again. Coffee is still hot, but milk foam works only weakly.

Can this be a coincidence? Does anyone know this problem? ... Solutions? - or has an idea for adjusting the steam pressure of the milk foamer? Tchibo thinks I should send the machine in for repair. Haha, every 7-9 months?

Hello, I have the same problem. Have you found a solution?
Kind regards Kathy

I also have the problem that the pump pressure has decreased. Milk foam was always great, now only 1 cm high. What can nan do
