How to Fix / Troubleshooting

Safety first: Unplug the washer before working on any low-voltage control wiring.

Steps to check and correct:

  • Inspect payment interface: Open the service compartment and locate the coin meter or card reader interface board.
  • Check harness connections: Ensure the harness from the payment device to the main control board is fully seated and not damaged.
  • Verify configuration: Enter IPSO service mode (refer to service manual) and confirm that the correct payment system type is selected.
  • Test payment device: If possible, substitute a known-good coin meter or card interface to see if E19 clears.
  • If error persists: The payment interface board or main control board may be defective and should be replaced with the correct IPSO parts.
