Possible Causes

Partially failed heating element, Incorrect temperature setpoints, Faulty NTC giving low reading, Scale buildup on heating surfaces

How to Fix / Troubleshooting

Safety first: Disconnect power and allow the machine to cool before accessing heaters.

  • Check displayed temperatures: Many Hoonved models show tank and boiler temperatures. Compare with setpoints in the manual.
  • Verify settings: Enter programming mode (if available) and confirm that wash and rinse temperatures are set correctly for your application.
  • Inspect for scale: Open the tank and boiler access to check for limescale. Descale using approved descaling agents.
  • Test elements and probes: Use a multimeter to check heater resistance and NTC values. Replace any components that are out of specification.
