Power Issues Diagnosis
Common Power Problems:
- No power to dishwasher
- Control panel not lighting up
- Dishwasher won't start cycle
- Sudden power loss during operation
- Intermittent power issues
Initial Power Check Steps
- Check Power Source: Verify the dishwasher is plugged in and the outlet is functioning properly.
- Circuit Breaker: Check your home's electrical panel for tripped breakers or blown fuses.
- GFCI Outlet: Test and reset any GFCI outlets that may be connected to the dishwasher circuit.
- Power Cord: Inspect the power cord for any visible damage, cuts, or fraying.
- Door Latch: Ensure the door is completely closed and latched, as many models won't power on if the door isn't secure.
- Child Lock: Check if the control lock or child safety feature is activated.
- Control Panel: Look for any error codes or flashing lights on the display.

Advanced Troubleshooting
Control Board Test
Check for proper voltage at the main control board. Look for burnt components or loose connections that may prevent power distribution.
Thermal Fuse Check
Locate and test the thermal fuse on the control board. If blown, this safety device will prevent the dishwasher from receiving power.
Door Switch Inspection
Test the door switch mechanism to ensure it's properly engaging when the door is closed, allowing power to flow to the control system.
Wiring Harness Examination
Inspect all wiring harnesses for damage, corrosion, or loose connections that could interrupt power flow to various components.
