Kenmore Washer Error Code Er

The Er code on a Kenmore washer stands for a processor reset error. It appears when the control board fails to save cycle information during a power interruption. Notably, this code does not produce an error beep like other fault codes. Pressing STOP/CANCEL will clear the display and allow you to restart the washer.

Yes, a single occurrence of the Er code after a power interruption is generally not a safety concern. The washer simply lost its cycle data and reset. If the code appears frequently without any power event, have the control board and wiring inspected before continuing heavy use, as repeated unexplained resets may indicate a developing electrical issue.

Recurring Er codes that are not linked to power outages suggest a problem beyond a simple one-time event. A failing control board with degraded memory components, consistently low or unstable supply voltage, or a loose wiring connection to the board can all cause repeated processor resets. Diagnosing the power supply voltage and inspecting the control board harness connections are the recommended next steps when the code repeats.

Pressing STOP/CANCEL is the recommended first step and will clear the Er code from the display in most cases. If the code was triggered by a one-time power event, the washer should operate normally after clearing it. If the code returns repeatedly without an obvious power disruption, further diagnosis of the control board and power supply is needed.

If the cause is a power fluctuation or a loose connection, there may be no repair cost at all. If the main control board needs to be replaced, parts and labor typically range from around $150 to $350 depending on the specific model and local labor rates. Checking your home circuit and connections first is always worth doing before investing in parts.
