Washing Machine Automation

We are having a semi automatic washing machine. Timer switch and drain switch are spoiled. I tried to replace them but it costs more money. We stopped using it. Then I thought to remove the manual switches and make it automatic. Then I tried this using arduino and worked well with lesser cost. I presented this to my grand mother. In their house there is no over head water tank system. So I didn’t try for automatic water filling. We have to fill water manually.
