Haier Dishwasher Error Code LED1:1 LED2:1 LED3:1 LED4:1 LED5:1

The LED1:1 LED2:1 LED3:1 LED4:1 LED5:1 error code on a Haier dishwasher indicates a door switch circuit fault. This code triggers when all five LED indicators illuminate simultaneously, which is the control board's way of signaling that it cannot confirm the door is properly latched and secured. The door switch is a critical safety component that tells the control board whether the door is open or closed. When this circuit fails, the dishwasher will not start or continue a wash cycle, since operating with an open or unconfirmed door would create a water leak hazard.

The door switch circuit includes the physical switch mechanism inside the door latch assembly, the wiring harness connecting it to the control board, and the board's input circuit that reads the switch state. A fault can originate at any point along this path. The switch itself may fail mechanically or electrically, the connector terminals may corrode or loosen, or the wiring between the switch and board may develop an open or short circuit. In some cases, the door itself may not be fully closing due to a warped gasket or misaligned latch, preventing the switch from actuating even though no electrical fault exists.

Diagnosis begins by confirming the door is fully closed and latched. If the error persists with the door closed, the next step is to remove the door panel and use a multimeter (avometer) set to continuity or resistance mode to probe the two terminals of the door switch directly. A properly functioning door switch should show continuity when the door is latched and no continuity when it is open. A reading that does not change between open and closed positions indicates a failed switch or an open circuit in the wiring leading to it.
