Charger shows E18; this may indicate a stuck button or a keypad fault on models with physical buttons.

Safety first: Turn OFF the power before removing the front panel or keypad assembly.

• 1. Check for stuck buttons: Press each button several times to ensure it moves freely and returns. If a button feels stuck, gently work it free; do not use excessive force.
• 2. Clean the front panel: Wipe the keypad area with a slightly damp cloth (with power OFF) to remove dirt or sticky residue. Do not spray cleaner directly onto the charger.
• 3. Inspect keypad cable: Remove the cover and locate the keypad ribbon cable. Reseat it at both the keypad PCB and the main control board.
• 4. Look for liquid damage: If there are signs of liquid ingress (stains, corrosion), the keypad PCB may need replacement.
• 5. Replace keypad module: If E18 persists and a specific button is non-functional, replace the entire keypad/front-panel PCB with an OEM EvoCharge part.

A faulty keypad can prevent starting or stopping charging; do not attempt to bypass button inputs with improvised wiring.
