Amana Washer Error Code Sr: Troubleshooting and Board... | appliancefaults.com

Technical Background:

The 'Sr' error code on an Amana washer typically indicates a fault within the main control board. This board houses the MCU (Microcontroller Unit), which controls all washer functions. The MCU relies on stable voltage inputs to operate correctly. Faulty components, wiring issues, or voltage fluctuations can disrupt the MCU's operation, triggering the 'Sr' error. Voltage paths are critical for proper communication between the MCU and other components like the motor and water valves.

Symptoms:

The Amana washer displays error code 'Sr' on the control panel. The washer may not start, may stop mid-cycle, or may exhibit other erratic behavior. Homeowner might report a burning smell or sparking from the unit before the error appeared.

Possible Causes:

Main Control Board Failure
Wiring Harness Issue
MCU (Microcontroller Unit) Fault
Voltage Supply Irregularity
Software Glitch or Corruption

Solution:

1

Unplug the washer from the 120V AC power outlet.
2

Locate and inspect the main control board for any visible signs of damage, such as burnt components or water damage.
3

Check the wiring harness connections to the control board, ensuring they are secure and free from corrosion.
4

Use a multimeter to test the voltage supply to the control board. Verify you are getting the correct voltage (typically 5V DC and 12V DC) according to the wiring diagram.
5

If the voltage supply is correct and the board appears damaged, replace the main control board.
6

After replacing the board, plug the washer back in and run a diagnostic cycle to confirm the error code is resolved.
7

If the error persists, consult the Amana service manual for further troubleshooting steps.

Safety Warning:

Disconnect power to the appliance before performing any troubleshooting. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage is present in the control board area; use caution when testing.

Prevention:

Regularly inspect the washer's power cord for damage. Avoid overloading the washer. Clean the dispenser drawers periodically to prevent buildup that could potentially affect the control board. Use a surge protector to protect the washer from power surges.

Expert Tip:

Many Amana washers have a service mode that can provide more detailed diagnostic information. To enter service mode, simultaneously press and hold the Start/Pause and Cycle Select buttons for 3 seconds. Refer to the service manual for specific diagnostic codes and procedures.

Frequently Asked Questions

•Where is the main control board located on my Amana washer?

The main control board is typically located behind the control panel or inside the washer cabinet. Consult the service manual for your specific model to find its exact location.

•What type of multimeter should I use to test the voltage supply?

Use a digital multimeter (DMM) with the ability to measure both AC and DC voltage. Ensure the multimeter is set to the appropriate voltage range for the test you are performing.

•Is it possible to repair the control board instead of replacing it?

While it is possible to repair some control boards, it requires advanced soldering skills and knowledge of electronics. In most cases, replacing the entire control board is the more practical and reliable solution for a technician.
