It is not recommended to run your dishwasher without the top rack in place. Doing so can cause a number of problems, such as:
- Dishes on the top rack may not get clean.
- Water may spray out from the dishwasher and onto your floor or countertop.
- The dishwasher may become unbalanced and start making loud noises.
- Your dishes may come out dirty if they are not properly secured on the racks.
