Kenmore Washer Error Code E31

E31 on a Kenmore washer indicates that the pressure sensor is not communicating with the main control board. This sensor monitors the water level inside the drum, and when the board loses its signal, the washer stops the cycle and displays E31. This code applies to better or higher-end Kenmore washer models. The issue is most often related to wiring or the sensor itself.

It is not recommended to continue running the washer while E31 is active. The pressure sensor controls water level monitoring, and without a reliable reading, the washer could potentially overfill or run a cycle incorrectly. The washer typically halts operation when this code appears as a precaution. Resolve the fault before resuming normal use.

A reset may temporarily clear the E31 code, but if the underlying wiring, sensor, or hose problem has not been fixed, the code will return when the washer tries to use the pressure sensor again. Resetting without diagnosing the root cause is not a long-term solution. Follow the wiring inspection procedure and address any faults found before relying on a reset to clear the error.

Many E31 repairs are DIY-friendly, especially if the cause is a loose connector or a detached pressure hose. Start by inspecting the wiring harness between the pressure sensor and control board, reseating any loose connectors. If the hose or sensor needs replacement, those parts are generally accessible without major disassembly. If the control board is at fault, that repair is more involved and may benefit from professional service.

Repair costs depend on the root cause. If the issue is simply a loose or corroded connector, the repair may cost nothing beyond your time. A replacement pressure sensor typically ranges from $15 to $60 in parts. A new pressure hose is usually inexpensive, often under $20. If the control board needs replacement, parts and labor costs can range from $150 to $400 or more depending on the model and service provider.
