How to Fix / Troubleshooting

Safety first: Allow the unit to cool before restarting to avoid burns.

Check external connections:

  • Ensure the power cord is fully inserted into the outlet and not loose.
  • Avoid using extension cords or power strips.

Descale:

  • Run a full vinegar cleaning cycle to remove scale that can cause overheating and premature shutoff.

If the unit consistently stops at the same point in the cycle after descaling, the thermal cutout or control board may be failing and should be replaced.
