About this pressure switch

This Balboa 56" pressure switch cable connects your spa's pressure switch to the control system, enabling proper water flow detection and safety shutoffs. The 56-inch length with 2-pin JST-style connector fits Balboa control systems across many spa brands and models.

Built to OEM specifications, this genuine Balboa replacement cable resolves common error codes including HH (high limit), ICE (insufficient circulation), and OH (overheat) conditions caused by faulty pressure switch connections. At Bubbles Supply, we guarantee an exact fit for your spa with same-day shipping on in-stock orders and back every purchase with a full 1-year warranty. Before installation, ensure your spa is powered off and verify the JST connector orientation matches your existing cable to prevent damage to the control board.

Common symptoms this part fixes

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

  • HH error code on control panel
  • OH (overheat) error code that won't clear
  • ICE error code indicating insufficient circulation
  • Spa shuts down unexpectedly due to false pressure fault
  • Control system fails to detect water flow despite pump running
  • Pressure switch reads open circuit when cable connector is damaged or corroded

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

Before you buy — quick checklist

  • Confirm your existing cable uses a 2-pin JST-style connector — visually inspect the connector at both the pressure switch and control board ends before ordering
  • Measure your existing cable length to confirm 56 inches is sufficient to reach between your pressure switch and control board without strain
  • Verify your control system is a Balboa unit — check the label on the topside controller or the control box
  • Inspect the pressure switch itself before replacing the cable — if the switch body is faulty, a new cable alone will not resolve error codes
  • Check the connector pins on the control board for corrosion or bent contacts, as a damaged board-side connector will cause the same fault symptoms

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