Possible Causes

Blown internal fuse on control board, faulty mains switch, defective power cord, failed power supply section on main board

How to Fix / Troubleshooting

Safety first: Ensure the machine is unplugged before opening. Mains voltages are present inside.

User-level checks:

  • Verify the outlet has power by testing with another appliance.
  • Check that any external power switch on the machine is in the ON position.
  • Inspect the power cord for visible damage.

Technical inspection:

  • Remove the outer cover to access the main control board.
  • Check the internal fuse(s) on the board; replace only with identical type and rating if blown, and investigate why it blew.
  • Inspect the mains switch and wiring for loose connections.
  • If fuses and wiring are intact but no standby voltage is present, the power supply section of the board is likely defective.

Resolution:

  • Replace a damaged power cord or mains switch.
  • Replace the main control board if the power supply is faulty; this should be done by a qualified technician.
