About this flow switch

The Sundance Jacuzzi Flow Switch 6560-857 is an essential safety sensor designed for Sundance spa systems. This OEM replacement part monitors water flow through your spa's plumbing, automatically shutting down the heater when flow drops below safe levels to prevent damage. The switch features 3/4" MPT threading for secure installation and operates at 0.5 amp, 10 watt specifications.

This genuine Sundance flow switch helps resolve common spa error codes including HH, ICE, and OH messages that indicate flow or temperature issues. At Bubbles Supply, we guarantee an exact fit for your Sundance spa with same-day shipping on in-stock items and back every part with our comprehensive 1-year warranty. Professional installation is recommended to ensure proper calibration and optimal spa performance.

Common symptoms this part fixes

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

  • HH error code displayed on spa topside
  • ICE error code displayed on spa topside
  • OH (overheat) error code displayed on spa topside
  • Heater shuts off unexpectedly during normal operation
  • Spa heater will not activate despite adequate water flow
  • Spa not heating and no circulation fault detected by board

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

Before you buy — quick checklist

  • Confirm your spa's control board is throwing HH, ICE, or OH fault codes before replacing — a faulty flow switch is one cause, not the only cause
  • Verify your existing flow switch uses 3/4" MPT threading before ordering
  • Check whether the issue may be low water flow itself (dirty filters, low water level) rather than a failed switch
  • Confirm this is an OEM Sundance part compatible with your specific spa model year and control system
  • Inspect the flow switch wiring harness and connector for corrosion or damage before assuming the switch itself has failed

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

Install difficulty: Medium — Some experience neededTypically 30–60 minutes
