dishwasher troubles.

I had a bad problem... My son played in the dishwasher one day and I didn't notice the plastic plate he had put in the bottom until I could smell it. It had melted all over the heating element and it smelled terrible every time I did the dishes. But I found this easy treatment. And I also did a load with cups of vinegar on the top rack and baking soda in the detergent dispenser. Now my dishwasher is happy again! Thank you Pinterest!
