Make sure that you have the lid on the dirty water container correctly. Also, you may want to check the filter located either under a clear triangular part on the front of the cleaner or on the bottom. You can clean it with a wetted finger. The only other thing I can think of is to check to make sure that the round black gasket that connects the dirty water container to the source of the suction is in place and present.
