32. EDC Error Code Listing

NOTE: Disconnecting power to the unit may clear the error display.

NOTE: If replacing an inoperative electronic control due to burnt pin(s) on the 6-pin wire harness connector

block, it may be due to damaged terminals in the harness connector. Damaged terminals in the harness

connector will appear burnt or show signs of heat discoloration on the connector block. Replace the control

wire harness with the control to avoid repeated damage.

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the washer before servicing.

• Never start the washer with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be

reconnected to ensure that the washer is properly grounded.

Errors beginning with “EI” refer to NetMaster Infrared communication errors. Errors beginning with “EC”

refer to NetMaster card reader errors. All other errors refer to electronic control errors.

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the washer before servicing.

• Never start the washer with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be

reconnected to ensure that the washer is properly grounded.
