Why?

Why must our dishwasher hate us?

A couple of weeks ago, it decided that it didn't know how to drain, so maintenance came and fixed it. But after they fixed it, apparently they broke somethingand it almost fell out on us when we opened it. So, they fixed that and now it doesn't fall out.

So, I go and wash the dishes in the dishwasher and then we open it and Poof! the water didn't drain again! Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaagh! Why why why!!!!

I give up.
