Roper Washer: Wash Plate vs Agitator for Heavy Loads -... | appliancefaults.com

Technical Background:

The washer's Main Control Unit (MCU) sends a signal to the drive motor to initiate the wash cycle. The motor's speed and direction are controlled by the MCU via relays and capacitors. Voltage is supplied through the breaker panel to the outlet, and from there to the washer. Low voltage or a faulty capacitor can affect motor performance.

Symptoms:

The homeowner reports that clothes are not getting clean, especially with larger or heavier loads. The washer seems to be running but the wash action is weak or nonexistent.

Possible Causes:

Clogged wash plate or agitator ports
Worn or damaged wash plate or agitator fins
Weak motor coupling
Failed drive motor capacitor
Restricted drain hose or pump
Low water pressure to fill valve

Solution:

1

Unplug the washer and disconnect the water supply hoses.
2

Remove the wash plate or agitator (typically secured with a bolt or screw). Use a 1/4-inch nut driver or socket set.
3

Inspect the wash plate or agitator for clogs or damage. Clean any debris with a stiff brush and water.
4

Check the motor coupling for wear or damage. Replace if necessary.
5

Inspect the drain hose for kinks or obstructions. Clear any blockages.
6

Verify water pressure to the fill valve. Should be at least 20 PSI.
7

Reassemble the washer and test the wash cycle. Monitor water level and agitation strength.

Safety Warning:

Always disconnect power to the washer at the breaker panel before performing any repairs. Use Lock Out Tag Out (LOTO) procedures. Be aware of high voltage components inside the washer's control panel.

Prevention:

Regularly clean the washer tub and dispenser to prevent buildup. Avoid overloading the washer. Check the water inlet hoses for kinks or leaks. Use the appropriate amount of detergent for the load size.

Expert Tip:

Enter the service mode by pressing and holding the start/pause button for 3 seconds while rapidly cycling the power button 3 times. This will allow you to run diagnostic tests on the motor and other components.

Frequently Asked Questions

•How do I test the motor capacitor on my Roper washer?

Disconnect power to the washer. Discharge the capacitor with a resistor. Use a multimeter set to capacitance to measure the capacitor's microfarad (uF) rating. Compare the reading to the capacitor's label. A reading significantly lower indicates a failed capacitor.

•What size is the bolt that holds the wash plate in place?

The bolt size typically varies depending on the specific Roper washer model, but it is commonly a 7/16-inch or 1/2-inch bolt. Check your parts diagram to be certain.

•Where can I find a replacement motor coupling for my Roper washer?

Replacement motor couplings can be found at most appliance parts stores or online retailers. Make sure to provide your washer's model number to ensure you get the correct part. Sears Parts Direct and AppliancePartsPros.com are two resources.
