Roper Washer Error Code Sr: Troubleshooting and Reset... | appliancefaults.com

Technical Background:

The error code 'Sr' on a Roper washer typically indicates a problem with the main control board (MCU). The MCU is responsible for controlling all the washer's functions, including motor operation, water levels, and cycle timing. The 'Sr' error suggests the MCU has detected an internal fault or is not receiving the correct signals from other components. This often involves monitoring voltage and current paths within the board.

Symptoms:

The Roper washer displays error code 'Sr' on the control panel and may not start or operate correctly. The washer may also exhibit erratic behavior.

Possible Causes:

Faulty main control board (MCU).
Wiring harness damage between the MCU and other components.
Loose connections on the MCU.
Voltage fluctuations causing MCU instability.
Failed component on the control board (capacitor, resistor, etc.).

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the main control board (MCU), usually behind the control panel. You may need a 1/4-inch nut driver to remove screws securing the control panel.
3

Visually inspect the MCU for burned or damaged components.
4

Check the wiring harness connected to the MCU for any damage or loose connections. Use a multimeter to check for continuity in the wires.
5

With the power disconnected, carefully disconnect and reconnect the wiring harness connectors on the MCU to ensure good contact.
6

Restore power to the washer and observe if the error code Sr reappears. If it does, the MCU likely needs replacement.
7

If replacing the MCU, ensure the new board is compatible with your model and follow the manufacturer's instructions for system. Cycle the power again after replacement.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed. The control board contains high voltage components that can cause electric shock.

Prevention:

Use a surge protector to protect the washer from voltage fluctuations. Periodically inspect the wiring harness for any signs of damage. Avoid overloading the washer, as this can strain the motor and put stress on the control board.

Expert Tip:

Some Roper washers have a service mode that allows you to run diagnostic tests and clear error codes. Consult the service manual for the specific sequence for your model. A common sequence involves pressing and holding certain buttons simultaneously.

Frequently Asked Questions

•Where can I find the main control board on my Roper washer model?

The main control board is typically located behind the control panel, at the top rear of the washer. You may need to remove screws or clips to access it. Refer to your washer's service manual for specific instructions and diagrams.

•How do I know if the wiring harness is damaged?

Inspect the wiring harness for any signs of fraying, cuts, or melted insulation. Use a multimeter to check for continuity between the wires. If there's no continuity, the wire is broken. Also check the connectors are firmly seated.

•Where can I purchase a replacement main control board for my Roper washer?

You can purchase a replacement main control board from appliance parts retailers, online marketplaces, or directly from the manufacturer. Make sure to verify the board part number matches your washer's model number to ensure compatibility. Verify its programmed.
