My dish washer hasn't worked is broken.

The housework what I hate is washing dishes because of my hands are weak for sensitive to detergents, even if I put wear kitchen gloves. So I always rely on the dishwasher instead of washing by myself hand.
But, that machine broke a few days ago; and I tried to fix it, but didn't work. Then the repair man came over and checked and see this one it today and said " It's an old one , so we don't have the parts of for this type of machine. I 'll would get this machine change into a re a new model." I accepted his opinion before seeing the cost of the a new one. It's so expensive to get a new one! I cannot afford to get it , but my hands are getting worse! What do I have to should I do?!
