First of all, what you have is a WOW pump that has an E-switch for a control. There is a knob on the top lip of your tub that you turn a 1/4 turn to turn this pump on/off. There is a small circuit board inside the box on top of the motor. This is likely the source of your problem. Here is your biggest problem. That little circuit board is not made anymore. We have the e-switch but you will be better off changing out the pump (which you have to do anyway) with a new WOW pump with an air switch and change the switch on the top lip of the tub to an air button which will turn the pump on/off.

Air Switch Repair It sounds like you have a bad air switch located in your motor. The air switch is what the air hose connects to on the back of the motor or on the box on top of the motor. The other end of the air hose is connected to the air button on the lip of the tub. This is a latching air switch and when you push the air button it latches to send power to the motor. When the air button is pushed again it opens the latch in the air switch and stops power going to the motor shutting it off. US Parts Center

Cleaning your Tub There are several options for cleaning the piping on a jetted bathtub. The reason you have a residue on the bathtub surface when you are done bathing is because there is bacteria built up in the plumbing of the jetted tub. In order to remove that and reduce the amount of "yucky stuff" coming into the tub when using it, we recommend a regular usage of a jet cleaning product about once every couple of months Here is a link to the cleaning products I can find right now. There may be other out there that I am not aware of but I do know these products work well in all jetted bathtubs. US Parts Center

Remove the faucet spout and unscrew the screw keeping the white plastic piece on the bottom (of the faucet). It's where the red and black tubes enter. Pull out the white plastic with the tubes and clear it of debris (usually placed there when your disposal backs up the black tube, which serves as the filter's drain tube). Once it is cleared of debris, make sure the black rubber washer is back in place (it may be stuck in the faucet, so look for it) and replace the plastic, screw the screw back in, and secure the faucet again. I had this same problem and doing this solved it. Should take about 5 minutes or so. Good luck.

Not sure where you are from but I have a Helena that we are replacing that has a good pump and motor. You may be interested in it even for parts.
