How to Fix / Troubleshooting

Safety: Disconnect from mains before opening the cabinet.

  • Identify boards: Locate the main control PCB and any secondary boards (inverter, sensor, display).
  • Check harnesses: Reseat all multi-pin connectors between boards. Look for bent pins or corrosion.
  • Inspect cables: Check for pinched or damaged cables, especially where they pass through metal panels.
  • Reset power: After reseating, unplug for a few minutes, then reconnect and test.
  • Board replacement: If E19 remains, one of the boards is likely defective and should be replaced following Amica service guidance.
