Bestway Lay-Z-Spa water flow sensor paddle and pin

Description

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.

NOTE:  Please check and make sure that this is the part that you need prior to ordering.  There are many causes of the E02 error and this is only one of them.  It may be worth it to check out my article “Fixing the dreaded E02 error on your Bestway, Coleman or Lay-Z-Spa tub” prior to purchasing this part.  I also have a second article that I wrote called “Repairing yourBestway, Coleman or Lay-Z-Spa water flow sensor.”  This article goes more in depth on how to fully test your water flow sensor using a multimeter prior to purchasing.
