The cycle will not start on a hydromassage bath with a self-clean function. What is the problem?

The problem is that there is insufficient self-clean liquid in the inner dispenser. The bath will need to be filled up with self-clean liquid. Once the correct amount of fluid has been put into the bath, the self-clean indicator light will go out; showing the correct volume of liquid is in the bath.
