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

Safety first: Before opening any panels, ensure the dishwasher is isolated from mains power.

• 1. Check household power: Verify the kitchen breaker feeding the Hisense dishwasher is ON and not tripped. Reset if necessary.
• 2. Test outlet or junction box: If the dishwasher is hard-wired, remove the lower kick plate and open the junction box. Confirm line and neutral connections are tight and not burned. For plug-in models, test the outlet with another appliance.
• 3. Inspect power cord and terminal block: Look for melted insulation, scorch marks, or loose screws where the cord connects to the dishwasher.
• 4. Control board fuse: Some Hisense models have an internal fuse on the main PCB. If you are qualified, access the board and check the fuse; replace only with the exact rating.
• 5. Replace main board if needed: If power is present at the board but there is no response, the Hisense main control board is likely defective and should be replaced by a professional.
