How to Fix / Troubleshooting

Safety first: Unplug the unit before any inspection. Do not attempt live testing unless you are trained to work with mains voltage.

  • Check outlet and breaker: Test the outlet with another appliance. Reset any tripped breakers or RCDs.
  • Inspect power cord: Look for visible damage. If the cord is cut, frayed, or burnt, it must be replaced.
  • Internal fuse: Remove the cover and locate the small glass or ceramic fuse on or near the control board. Test for continuity with a multimeter. Replace only with the same type and rating if blown. If it blows again immediately, there is a deeper fault.
  • Board inspection: Look for burnt components or cracked solder joints on the control PCB. If present, replace the board rather than attempting component‑level repair.
  • Professional help: If you are not comfortable working around mains circuits, contact a qualified technician.
