Roper Washer Not Draining: Troubleshooting Guide - Solar... | appliancefaults.com

Technical Background:

The Roper washer's MCU (Main Control Unit) sends a 120V AC signal to the drain pump motor at the appropriate time in the cycle. The pump then evacuates the water through the drain hose and standpipe. The lid switch ensures the washer only operates when the lid is closed for safety. Faulty components or blockages interrupt this process.

Symptoms:

The Roper washing machine completes its wash cycle but fails to drain the water. Water remains standing in the tub after the cycle ends.

Possible Causes:

Clogged drain pump filter
Kinked or blocked drain hose
Faulty drain pump motor
Defective lid switch
Failed timer or electronic control board (MCU)

Solution:

1

Unplug the washer from the outlet.
2

Locate and clean the drain pump filter (usually behind a small access panel at the bottom front of the machine). A 1/4-inch nut driver may be required to remove the access panel screws. Remove any debris.
3

Inspect the drain hose for kinks, clogs, or damage. Disconnect the hose from the drain standpipe and the pump. A 5/16-inch socket might be needed for hose clamps. Flush it out with water, and check for obstructions.
4

Check the drain pump motor for continuity using a multimeter. Set the multimeter to the ohms setting. A reading of OL (open loop) indicates a failed motor. Replace the pump if necessary.
5

Verify the lid switch is functioning correctly. Use a multimeter to test continuity when the lid is closed. If there is no continuity, replace the lid switch.
6

If the above steps don't resolve the issue, the timer or electronic control board may be faulty. Replacement might be required.
7

Reassemble the washer and test the drain cycle.

Safety Warning:

Always disconnect the power supply (unplug the washer) before performing any repairs. Lock-Out/Tag-Out (LOTO) procedures should be followed. Be aware of potential electrical hazards when working with electrical components. Some components carry 120V AC.

Prevention:

Regularly clean the drain pump filter (every 3-6 months) to prevent clogs. Avoid overloading the washer, as this can strain the drain pump. Inspect the drain hose periodically for kinks or damage.

Expert Tip:

To quickly check the drain pump, you can often access it from underneath the washer by tilting it back carefully (after unplugging, of course). This gives you a better view and easier access to disconnect the wiring and hose.

Frequently Asked Questions

•How do I access the drain pump filter on my Roper washer?

The drain pump filter is usually located behind a small access panel at the bottom front of the washing machine. You might need a screwdriver or nut driver to remove the panel.

•What resistance reading should I expect from a functioning drain pump motor?

A working drain pump motor typically has a resistance reading between 10 and 30 ohms. Consult the service manual for the specific model for exact values.

•How do I know if the electronic control board is the problem?

If you've ruled out all other possible causes, such as a clogged drain, faulty pump, or lid switch, and the washer still won't drain, the electronic control board is the most likely culprit. However, electronic control boards are expensive, so double-check everything else first.
