First Home Improvement Incident

Well we are homeowners and what comes with being a homeowner is... repairs!  

The other night I loaded and started the dishwasher and then headed out to youth group, the kids were with a sitter.  I got a phone call from the sitter and she said she was smelling something burning in the kitchen and opened the dishwasher and found the bottom water sprayer thingy had unattached and had fallen right on the heat source...:(  I was able to later detach the piece and I am sure we can replace just that piece but I have not heard back from the place that I called??  I just needed to know how much the part was and I called on Thursday and never heard back from them??  

I guess all I can do is wait for the hubby to get home and figure it out.   Also, Praise God that it only melted some plastic and no other damage occurred!
