Starts beeping and F31 ERR flashes

Please do the following to fix the problem:
1. Power cut: First, unplug the washing machine and wait a few minutes.
Then plug it back in and try starting the app again.
2. Resetting the washing machine: If turning off the power alone does not solve the problem, you may need to reset the machine.
To do this, press and hold the Quick Start button for 5 seconds to reset.
Then try starting the program again.
3. Checking the water level: Make sure that the water level in the washing machine is correct and that the water supply line is connected correctly.
If the water level is low, it may cause "Err 105" error.

It looks like the probe is the same as the temperature sensor.

On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner's manual for instructions on how to recalibrate the oven control.

Since you're getting an error message the following may apply:

OPEN PROBE CONNECTION
1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor Probe connector.

SHORTED PROBE CONNECTION
2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector. .

Consult the manual first, if there is no troubleshooting , contact your dealer (thinking about the warranty term)

Hello - This manufacturer does not show to have such an error code for a wall oven. However the error codes F30/F31 indicates that the unit either has an issue with the oven sensor, wiring with the EOC or the probe connections is open or shorted. Contact a professional to move forward accurately.

i would guess that you have a faulty main board, the quickest and surest way to determine the problem and that is to replace it with a second hand board out of an known old machine which has faulty seals.

1. Press and hold the "Clock/Timer" button until you hear a beep and the time starts to flash.
2. Adjust the time using the "Hour" and "Minute" buttons. Note the clock includes AM/PM.
3. Tap the "Clock/Timer" button to restart the clock.

I have a similar problem with my electric Frigidaire convection oven, which flashes ERR F9 and beeps after finishing a cleaning cycle; if you haven't had to have it repaired professionally by now you might try cutting the circuit breaker to the oven for a few seconds and then turning it back on. My oven takes a few minutes to reset, after the circuit is turned back on, but then will unlock the door and let me reset the clock and continue cooking as normal. . . until the next time I set the clean cycle.
