Samsung refusing to replace a clearly faulty Washing machine

I am totally disappointed with the level of service I have received from a premium brand Samsung. I bought a washing machine and within the 2nd month we noticed issues with this machine and I contacted the call center to send out a technician but I was repeatedly told to do a clean cycle and add vinegar and baking soda for months. Eventually after having enough of being told this, i logged a complaint on Hello Peter and then only a technician came out and this was 12 months after i purchased it. The technician immediately saw a problem and replaced the water sensor and the shocks of the machine. The problem was not fixed and a week or 2 the technician came out again and saw the water sensor was faulty and replaced it with a new one. Problem was still there and tech came again to replace the water sensor only to see that the new sensor he just fitted was faulty and he requested a new batch from the factory then he came to replace the water sensor and the PC board. The problem is still there! This machine is faulty and no matter what they replace, the problem will still be there. No one can tell me what is causing the water sensor to break. Samsung is refusing to refund or replace the machine with a working machine
