How do I fix my Bosch Dishwasher SHU43C06UC/17?

Last night, a friend loaded the dishwasher poorly, They overloaded it with pots that were too large then started the cycle. I went in a few minutes later and there was water coming out from under the dishwasher and a slight burning smell. Now the dishwasher won't move past 95 minutes signal and no water is coming in. Is there something I can do, or is it too much for me and I should just call a repairman?
Thanks
