About this spa pump

The Waterway Genesis 3/4 HP spa pump delivers reliable single-speed circulation for residential spas and hot tubs. This 115V pump operates at 7.5 amps with a standard 48Y frame configuration, making it a direct replacement for worn or failed main circulation pumps in many spa systems.

Built to Waterway's exacting OEM standards, this Genesis pump provides the exact fit and performance your spa requires. At Bubbles Supply, we guarantee precise fitment and back every pump with our comprehensive 1-year warranty. Most orders ship same day for minimal downtime. Before installation, verify your existing pump's horsepower, voltage, and plumbing connections match this 3/4 HP 115V specification to ensure proper operation and optimal spa performance.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Pump won't start or trips breaker on startup
  • Motor hums but impeller won't spin
  • Weak or no water flow through jets
  • Pump runs but shuts off on thermal overload
  • DR or FLO error code on spa topside display
  • Loud grinding or seized motor

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing pump is 115V — do not install a 115V pump on a 240V circuit
  • Verify the horsepower rating on your old pump's motor label matches 3/4 HP
  • Confirm your spa uses a 48Y frame motor — measure or check the old pump label
  • Check plumbing union sizes on your existing pump before ordering — this pump must match
  • Confirm single-speed wiring at your equipment bay — two-speed systems require a different pump
  • Take a photo of the old pump's label before removal to cross-reference all specs

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
