Frigidaire Dishwasher Error Code ER

If your Frigidaire dishwasher is displaying the error code ER, it signals a membrane switch failure. Essentially, this means that one of the keys on the control panel is sending an incorrect signal. This glitch can also be triggered by a key getting stuck or being pressed for an extended period, exceeding one minute.

Troubleshooting Steps:

1. Inspect Control Panel Keys: Begin by scrutinizing the keys on the control panel. Check for any visible damage, debris, or signs of wear. A malfunctioning key might be the root cause of the error.
2. Examine Wiring Between Keypad and Main Control Board: Inspect the wiring connecting the keypad to the main control board. A loose or damaged connection can lead to signaling errors. Ensure all connections are secure and free from any wear and tear.
3. Addressing Stuck or Over-Pressed Keys: If a key appears to be stuck, gently try to release it. Additionally, if a key has been pressed for more than one minute, release it and observe if the error persists.
4. Replacement of Keypad: If the issue persists after the above steps, it might be necessary to replace the keypad. A malfunctioning membrane switch requires a new keypad to ensure accurate signaling.
5. Consider Main Control Board Replacement: If replacing the keypad doesn’t resolve the error, the main control board may be the culprit. A malfunction in the main control board can disrupt communication between the keys and the dishwasher’s functions.

If, after following these steps, the ER error code continues to haunt your dishwasher, seeking professional assistance may be the next logical step. A certified technician can conduct a thorough diagnosis, pinpoint the exact issue, and recommend the appropriate course of action, whether it involves keypad replacement or addressing a malfunction in the main control board.

In conclusion, understanding the Frigidaire dishwasher error code ER and taking systematic steps to troubleshoot can often lead to a resolution. However, should the problem persist, consulting with a qualified technician ensures a comprehensive and accurate solution to get your dishwasher back in optimal working condition.
