Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

How to Fix / Troubleshooting

Safety: Turn off power before accessing wiring or control board.

Check mains stability: If other appliances flicker or reset, have an electrician check the household supply.
