My Bosch TDS6080 Steam Generator Iron Cannot Be Repaired Anymore

I purchased the Bosch TDS6080 steam generator iron from the Bosch dealer in Kars about 4–5 years ago. For the past 2 years, the product has been leaking water during every use, making ironing almost impossible. I took it to service 2 years ago and paid ₺250, but the same problem occurred again as soon as I brought it home. Yesterday, I applied again to the Bosch service center in Erzurum, but I was told that there are no spare parts and the iron cannot be repaired. Until now, I have not contacted customer service and tried to resolve the issue only through authorized service centers, but I could not get any result. The warranty of my product has expired. I was generally satisfied with the iron and would like to continue using it, so I request that spare parts be supplied and my product repaired.
