Sage Reduced heating performance / partial element failure

Preheat takes significantly longer than specified in the manual.

Safety Warning

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

Partially open heating element (one section failed), Low mains voltage, Excessive grease on heater reducing heat transfer, Failing relay causing intermittent heater power

How to Fix / Troubleshooting

Safety first: Unplug and cool before internal checks.

Measure preheat time: Compare actual preheat time to manual under similar load and room temperature.
Clean heater: Remove grease buildup on the element and surrounding surfaces.
Check mains voltage: If possible, measure voltage at the outlet under load. Low voltage can slow heating.
Test heater resistance: Compare measured resistance to specification. A significantly higher resistance may indicate partial failure; replace the element.
