CLR .works well

first check the air switch hose that connects to the "button"
Open the access for the pump there should be 1/4" poly tubing (probably clear) that connects to the pump motor. It just slides over a barbed nipple usually located somewhere on the back of the pump housing opposite the pipe connections. Make sure it is in place properly. If it is in place then look else where. The tubing also connects to the back of the air switch "button". This button connection rarely fails, especially if the tub was working and now does not. But if the tub is newly installed and may have disconnected during installation. this connection is probably going to be difficult if not impossible to verify since it is usually concealed after installation.
Some pump motors have resets some do not. If it does it probably is on the very back of pump opposite the pipe connections.
Also check to make sure that any electrical outlets in the bathroom, or any where in a nearby radius of the tub, to see if they have "GFI" reset buttons and make sure that they havn't tripped by pushing in the button between the plug-ins named "reset". Usually the circuit for the pump will be tied into one of these switches to add ground fault protection to the circuit.
If your pump is not working after checking these things it may be dead. Does your pump "hum" after pushing the button? Do you smell any type oder around the pump that would suggest a "burnt motor"?
If the pump is dead you will have to replace it.
