Kenmore Dishwasher Error Code nE

The nE code on a Kenmore dishwasher indicates a Vario system error, meaning the control board cannot detect the position of the vario cam. The vario cam is part of the mechanism that directs water to the spray arms, and its position is monitored by a vario switch. When that signal is lost or absent, the dishwasher stops and displays nE. The first step is to check the wiring connection to the vario switch and reseat it if necessary.

No, you should not attempt to run the dishwasher while the nE code is active. The dishwasher halts operation specifically because it cannot confirm the vario cam is in a valid position, which means the water distribution system may not function correctly. Running the machine in this state could result in poor wash performance or potential mechanical stress on the vario components.

If the fix is simply reseating a loose connector, the repair can cost nothing beyond your time. If the vario switch needs replacement, parts typically range from around $20 to $60 depending on the specific model, plus labor if a technician is called. In the unlikely event the control board is at fault, repair costs can rise to the $150 to $350 range or more including parts and labor.

In many cases, yes. The nE error is often caused by a loose wiring connector at the vario switch, which can be reseated without special tools. You should disconnect power to the dishwasher before inspecting any wiring. If reseating the connector does not resolve the issue, replacing the vario switch is a moderately straightforward repair for someone comfortable working with appliance components.

A reset may temporarily clear the nE code, but if the underlying issue is not resolved, the code will return once the dishwasher runs a cycle and the control board again fails to detect the vario cam position. A reset is not a fix, it is only useful to confirm whether the fault is intermittent. The wiring connection and vario switch should be inspected and addressed to permanently clear the error.
