Dishwasher will not power on at all; no lights or display, no response to buttons.

Safety first: Do not open electrical panels while the unit is plugged in. Turn off the breaker before inspecting internal parts.

• Check household power: Verify the kitchen outlet has power by plugging in another device. Reset any tripped GFCI or breaker.
• Inspect power cord: Ensure the Ikea dishwasher's power cord is firmly plugged in and not damaged or pinched behind the cabinet.
• Check junction box (hardwired models): If hardwired, remove the kick plate and inspect the junction box for loose wire nuts or burned connections (power off first).

If power is present at the junction box but the dishwasher remains dead, the mains filter module or main control board may have failed. This requires professional diagnosis and replacement.
