My aunt has a Kenmore Elite range and it begam flashing a "PO" error message. Can you tell me what this means?

If during the water heating step in the wash cycle, the water temperature sensor (NTC) value is out of range, or the heating element circuit has failed, the "F/05" error code will be displayed.

: What does F23 error code message mean on Kenmore Elite built-in double ovens?

Resolution

: Error code

F 23

indicates the control detected a problem with the communication link or can be generated as a result of irregularities in the power supply or usage.

The error code

F23

can often be resolved by removing power to the appliance for a minute and then restoring the power.

By unplugging the appliance it allows the control to receive a fresh supply of power. This in turn will clear the controls memory of any irregularities it may have received from the power supply. Once refreshed the error should no longer be displayed.

Unplug the unit or turn the circuit breaker off for 60 seconds.

Restore the power to the appliance by plugging it back in or turning the circuit breaker back on.

Check to see if the error code is still displayed on the range.

Run the appliance in the cycle that initially caused the error or attempt to turn on broiler.

If the error code is displayed, then service is needed.

Note

if its a Kenmore model then this message says that the button control board has lost sight of the main control board , but its been my experience that this maybe able to be reset and it may never come back or it will not reset and the control board will need replaced (50/50)


cycling power may reset this

The F50 error code indicates that the RPS (rotor position sensor) detects no motor rotation. Check to see if the basket spins freely. If not, you could have an item caught between the outer tub and the inner spin basket. A toy or other item underneath the washer could also prevent the basket from spinning and would result in this F50 code.

If the basket spins freely, you could have a wiring failure that would prevent the motor from spinning.

The "F2 - E0" error code means "Shorted keypad".

Remove power from the range, open the control panel and unplug the membrane switch ribbon from the control board.

Reconnect power to the range and observe for an hour.

If the error code reappear - replace the control board.

If not - replace the membrane switch

Hope this helps; keep us updated.

The F30 error code means the temperature sensor probe is open. First check the wiring, then check the probe. And if necessary, switch to a meat thermometer instead of a sensor probe. F31 is the error for a shorted temperature sensor probe.

Call Kenmore if you bought it new they may have a record of your serial number and be able to tell you what the error message means and if you need a service call to fix or you can do it yourself. my serial number is on the back of the washer on a sticker or a typed silver tag that is attached to the washer.
