This water flow sensor repair kit contains both the replacement magnetic paddle, the paddle retainer pin and a replacement o-ring seal 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 Water flow sensor repair 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. You also receive a high quality replacement silicone o-ring to replace your worn one under the cap. Also, If your pin is broken, no need to worry due to popular demand I am now including a replacement paddle retaining pin in every kit. If your o-ring is still in good shape and all you need is the paddle and pin , check out my other kit by clicking here.
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.
