Dishwasher will not power on; no lights or display activity

Safety first: Verify the breaker is off before opening any electrical covers.

• 1. Check building power: Confirm the circuit breaker feeding the dishwasher is on and not tripped. Reset if necessary.
• 2. Inspect power cord and plug: For cord-connected units, ensure the plug is fully inserted and the cord is undamaged.
• 3. Test main power switch: Use a multimeter to verify that the main on/off switch passes voltage when turned on. Replace if faulty.
• 4. Check terminal block: Open the electrical junction box and tighten all terminal screws. Look for burned wires.
• 5. Internal fuse: Some Jet Tech models have an internal fuse on the control board. Replace only with the exact type and rating.
• When to call a technician: If power is present at the machine but the control remains dead, the main PCB may be defective and should be replaced by a professional.
