Heated model does not seem to warm the solution, but no error is shown

Safety first: Unplug and allow the machine to cool before accessing the heater.

• Confirm expectations: Many Vax heated models maintain solution temperature rather than making it hot to the touch. Slight warmth may be normal.
• Check heater indicator: Ensure any heater indicator light comes on when the function is selected.
• Inspect wiring: Access the heater and check for loose or burnt connectors. Reseat or replace as needed.
• Descale heater: If accessible, flush the heater with a descaling solution suitable for small appliances, then rinse thoroughly.
• Test heater element and thermostat: Use a multimeter to check continuity. Replace the heater assembly or thermostat if open circuit.
