Display shows E1 and buttons do not respond properly

Safety first: Unplug the softener before removing the control cover or keypad.

Steps to check:

• 1. Inspect for moisture: Remove the control cover and look for condensation, water stains, or salt dust on the keypad and board. Dry gently with a soft cloth.
• 2. Reseat ribbon cable: If the keypad connects via a flat ribbon cable, unplug and reinsert it fully into the connector on the control board.
• 3. Test button response: Plug the unit back in and test each button. If some or all buttons still fail, the keypad membrane is likely defective.
• 4. Replace keypad or UI assembly: Order the correct Whirlpool user interface or control cover assembly and replace according to the service instructions.

When to call a technician: If the keypad and cable are new and E1 persists, the main control board may also be damaged and require professional diagnosis.
