Dishwasher will not start; control panel lights may be frozen or unresponsive; sometimes beeps and then shuts off.

Safety First: Unplug the dishwasher or switch off the circuit breaker before removing any panels.

Step-by-step checks:

• Power reset: Turn the breaker off for 5 minutes, then back on. Try to start a normal cycle. If the code returns immediately, continue.
• Check keypad response: Press several different buttons. If some work and others do not, the user interface (UI) panel may be shorted and confusing the control.
• Inspect wiring to control: Remove the inner door panel to access the main control board. Look for burnt spots, melted connectors, or loose harness plugs. Reseat all connectors firmly.
• Check for moisture: If there is condensation or signs of water intrusion near the control, dry the area thoroughly and correct any door gasket or vent leaks before replacing parts.
• If visible damage or repeated F1E1 persists: Replace the main control board (and UI panel if there are signs of keypad failure). Transfer wires one at a time from old board to new to avoid miswiring.

When to call a pro: If you are not comfortable working with live wiring or the control board, contact a qualified appliance technician.
