Bestway flow sensor flapThis is a replacement flow sensor paddle and nylon retaining pin for the Bestway family of inflatable hot tubs which include the Coleman and Lay-Z-Spa brands.   Failure of this part will cause your pump/heater unit to display E02.  There are a number of things that can cause the E02 error and failure of this part should be confirmed before purchasing.

This is a replacement magnetic paddle for the water flow sensors used in the Bestway, Coleman and Lay-Z-Spa brands of inflatable hot tubs.  If your pump/heater unit is displaying an E02 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 is the most likely cause of your E02 error.   The fully assembled flow sensors are selling for between $50 and $75.  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.  Other 3D printed versions like the one to the right seen on Ebay and other sites have the magnet exposed which will cause quick failure of the part due to the exposure of the magnet to water.  Be weary of these and do not buy them.  Due to popular demand I am now including the nylon retaining pin with the paddle as a kit.  We understand that these pins commonly break and we want you to have ALL the parts necessay to fix your water flow sensor right.
