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 immediately
  • Motor hums but impeller won't spin
  • Weak or no jet pressure throughout the spa
  • Spa displays DR or dry heater fault code
  • Pump runs hot and shuts off on thermal overload
  • Visible seal leak at motor/wet end junction

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

Before you buy — quick checklist

  • Confirm voltage on your existing pump label matches 230V — do not assume
  • Verify the HP rating on the old pump's nameplate reads 2.5 HP
  • Confirm your existing motor uses a 48Y frame — measure or check label before ordering
  • Check your spa's plumbing union size to ensure the wet end ports will mate to existing fittings
  • Note whether your current pump is single-speed or two-speed — this is a single-speed replacement only
  • Confirm the SKU 6500-341 appears on your existing pump label or spa documentation before ordering

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