Cycle takes long time to start - Blomberg?

I bought a blomberg dishwasher about a month ago. The first time I tried the quick wash, it took about 30 minutes to complete, like it was suppose to. Know, when I select the same cycle, it takes a really long time before the cycle starts. The water runs in the machine, but it stops there for a long time. Just tonight, it's been almost an hour since I pushed the start button, but the cycle still has not begin. Can someone help me?
