This can be caused by a problem with the water supply, such as a kinked hose or a clogged filter. To fix this problem, you will need to identify and fix the source of the problem.

The soap dispenser is not turned on: This may seem like a silly mistake, but it is actually a common one. Make sure that the soap dispenser is turned on before you try to use it.
