Washer will not power on at all; no lights or display, but mains socket is known to be live.

Safety: Always unplug the washer before opening any panels. If you suspect a short or burning smell, do not re-energize until inspected.

• Check wall outlet and plug: Test the socket with another appliance. Inspect the washer’s plug and replace the fuse if blown (use the correct rating, typically 13A in the UK).
• Inspect mains cable: Look for cuts, crushing, or burn marks. Replace the cable if damaged.
• Check mains filter: Remove the rear or top panel to locate the mains interference filter (often where the power cord enters). Ensure all spade connectors are tight. A cracked or burnt filter must be replaced.
• On/off switch: Access the control fascia and test the power button or rocker switch for continuity when pressed. Replace if faulty.
• PCB supply: If comfortable and with power disconnected, verify that the live and neutral reach the main PCB. If they do but the board is dead (no LEDs, no response), the PCB power supply section may have failed.

Work on live mains circuits is hazardous. If you are not experienced with electrical testing, contact a qualified technician.
