GE Washer Error Code E31

E31 on a GE washer means the pressure sensor is not communicating with the main control board. The pressure sensor monitors water levels inside the tub and feeds that information to the control board to manage fill and drain cycles. When that communication path fails, the washer generates E31 and stops operating normally. This code appears on better-model GE washers equipped with advanced diagnostics.

A reset may temporarily clear the E31 code, but it will return if the underlying communication problem between the pressure sensor and control board has not been fixed. Resetting the washer is not a repair and should only be used as part of the diagnostic process. Continuing to run the machine without addressing the root cause can lead to incorrect water levels and potential damage.

Repair costs vary depending on which component has failed. If the issue is a wiring or connector problem, costs may be low, typically in the range of $50 to $150 for a service call and minor repair. A replacement pressure sensor generally runs between $20 and $80 for the part, plus labor. A main control board is the most expensive possibility, with parts and labor potentially ranging from $200 to $450 or more depending on the model.

Start by inspecting the wiring harness between the pressure sensor and the control board, following Test 5 in the diagnostic procedure. Check for loose connectors, corroded terminals, and any pinched or broken wires. If the wiring is intact, test the pressure sensor itself and replace it if it has failed. If both components check out, the control board may need to be replaced.

It is not recommended to run the washer while E31 is active. Without reliable water level data from the pressure sensor, the control board cannot accurately regulate how much water enters or drains from the tub. This could result in overfilling, improper wash cycles, or other operational problems that may cause water damage.
