Safe checks you can make

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

  • Record the exact display string shown (including flash patterns)

If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.
