Roper Washer Error Code F2E1: Stuck Keypad Button... | appliancefaults.com

Technical Background:

The F2E1 error code indicates a problem with the user interface (UI) or keypad. The Main Control Unit (MCU) monitors the voltage levels from the keypad matrix. When a button is pressed, it changes the voltage on a specific line. If the MCU detects a voltage change that indicates a button is always pressed (stuck), it throws the F2E1 error.

Symptoms:

The washer displays error code F2E1. The washer may be unresponsive or behave erratically. One or more buttons on the control panel may appear to be constantly pressed, even when they are not.

Possible Causes:

Stuck or shorted button on the control panel.
Moisture or debris affecting the keypad.
Faulty membrane switch on the control panel.
Damaged wiring harness connecting the control panel to the main control board.
Defective main control board (MCU).

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Inspect the control panel for visible signs of damage, moisture, or debris.
3

Disconnect the wiring harness from the control panel and inspect the connector pins for corrosion or damage.
4

Using a multimeter, check the continuity across each button on the control panel. A stuck button will show continuous continuity when it should not.
5

If a button is stuck, attempt to clean the keypad with a dry cloth or compressed air. Do not use excessive moisture.
6

If cleaning doesn't resolve the issue, replace the control panel. If the control panel tests okay, replace the main control board.
7

Reconnect power to the washer and test its operation.

Safety Warning:

Always disconnect power to the washer at the breaker panel before performing any repairs. The washer contains high voltage components that can cause serious injury or death. Lock Out/Tag Out (LOTO) procedures should be followed.

Prevention:

Avoid spilling liquids on the control panel. Regularly clean the control panel with a dry cloth. Do not use excessive force when pressing buttons.

Expert Tip:

Some Roper washers have a diagnostic mode that can help pinpoint the faulty button. Refer to the service manual for the specific key sequence to enter diagnostic mode. Once in the mode, pressing each button should register on the display, confirming the button is functioning correctly.

Frequently Asked Questions

•What is the part number for the control panel on my Roper washer model?

The part number can be found on the model and serial number tag, usually located inside the washer lid or on the back panel. You can also search online using your washer's model number and 'control panel'.

•How do I test the wiring harness for continuity?

Using a multimeter set to the continuity setting, place one probe on each end of the wire you want to test. If the multimeter beeps or shows a reading close to zero ohms, the wire has continuity and is good. If there's no beep or a very high resistance, the wire is broken or corroded.

•What voltage should I expect to see on the wiring harness connector pins when the washer is powered on?

The voltage levels on the wiring harness connector pins will vary depending on the specific washer model and the button being pressed. Consult the service manual or wiring diagram for your washer model to determine the expected voltage levels.
