AquaRest Spas Localized Overheating / Poor Circulation

The spa shell surface around jets or seats feels unusually hot to the touch even when the water temperature is normal.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked return jets, low overall water circulation, heater cycling with restricted flow, insulation packed tightly against the shell in one area

Safety: Avoid prolonged skin contact with hot surfaces and turn off power before moving insulation.

Step 1 – Check jet flow: Ensure all jets are open and flowing strongly. Clean or replace the filter to improve circulation.
Step 2 – Inspect insulation: Remove side panels and verify that insulation is not tightly packed against the shell near heater return lines. Gently reposition it if necessary.
Step 3 – Verify heater flow: Confirm that the circulation pump is running properly and that there are no flow errors.

If localized overheating persists, have a technician inspect the plumbing and heater placement.
