New automatic washing machine, only today you can take it away

A new Admiral brand automatic washing machine, but the water at my place has rust and I damaged it slightly; I brought a technician to clean it, but he said the problem is with your water, it will need cleaning afterwards. It works perfectly and everything is fine, just don't run a full wash cycle.. I'm asking 250 or 200, you choose, otherwise it won't come to me except in vain, please
