Water flow sensor paddleThis is a replacement magnetic Water flow sensor paddle for the water flow sensors used in the Intex PureSpa brands of inflatable hot tubs.  If your pump/heater unit is displaying an E90 error and you find that your magnet is rusty due to the plastic cracking or other things like the one to the left, you should replace it with a new one as it could be one cause of your E90 error.   The fully assembled flow sensors are selling for between $35 and $50.  Why spend all that money when you can repair this yourself.  The part you are buying is a 3D printed version made from ABS plastic with the magnet completely sealed to prevent it from being exposed to the water and rusting yet again.  

NOTE:  Please check and make sure that this is the part that you need prior to ordering.  There are many causes of the E90 error and this is only one of them.  It may be worth it to check out this youtube video (click here) before purchasing .
