This genuine replacement part addresses common heating issues including complete heating failure and insufficient heat output.

Before you buy — quick checklist

Confirm your existing element is rated 5.5KW and 230V — do not substitute wattage or voltage
Verify your heater assembly accepts a hairpin-style element before ordering
Inspect the heater manifold for scale buildup or corrosion that may have caused the original element failure
Test the high-limit sensor and thermostat before replacing the element — a faulty sensor can burn out a new element quickly
Confirm this is an OEM HydroQuip assembly (check the heater housing label for the HydroQuip brand marking)

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