Hobart dishwasher will not start; no response when start button is pressed, though power is available.

Safety first: Ensure power is available but do not bypass any safety devices.

• Confirm door/hood closure: Make sure the door or hood is fully closed and latched. Check for racks or utensils preventing closure.
• Check emergency stops: Reset any emergency stop buttons or external safety interlocks connected to the dishwasher.
• Inspect door switch: Listen for a click when closing the door. If absent, the door switch may be misaligned or failed and should be inspected and replaced if necessary.
• Power cycle control: Turn off the breaker for 1–2 minutes, then restore power to reset the control. Attempt to start a cycle again.
• Further diagnosis: If the machine remains unresponsive, the main control PCB or user interface may require professional testing and replacement.
