Roper Washer Not Finishing Cycle or Stuck on Rinse:... | appliancefaults.com

Technical Background:

Modern washing machines use a Main Control Unit (MCU) to manage the different stages of a wash cycle. The MCU receives input from various sensors (water level, door switch) and controls outputs like the water inlet valves, drain pump, and motor. A fault in any of these components or the MCU itself can cause the cycle to stall.

Symptoms:

The Roper washing machine starts a cycle but either fails to advance past the rinse cycle, or gets stuck and never finishes the complete wash cycle. Clothes may be soaking wet at the end of the cycle.

Possible Causes:

Clogged drain pump filter
Defective water level sensor
Faulty drain pump
Malfunctioning timer or electronic control board (MCU)
Blocked drain hose

Solution:

1

Unplug the washer from the outlet.
2

Inspect and clean the drain pump filter (usually located behind a small access panel at the bottom front of the washer). Use a flat-head screwdriver to remove the access panel.
3

Check the drain hose for kinks or clogs. Disconnect the hose from the drainpipe and inspect for obstructions.
4

Test the water level sensor using a multimeter. The sensor should have continuity when the tub is empty and change resistance as the water level rises. Replace if faulty.
5

Test the drain pump for continuity using a multimeter. A reading of around 10-20 ohms is typically expected. If there is no continuity, replace the drain pump.
6

If the drain pump and water level sensor are good, the problem may be with the timer or electronic control board. Replacing the control board may require licensed technician assistance.
7

After replacing any parts, plug the washer back in and run a test cycle to verify the repair.

Safety Warning:

Always disconnect the power to the appliance at the breaker panel before performing any repairs. Washing machines operate on 120V AC, which can be lethal. Use proper Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Regularly clean the drain pump filter every 3-6 months. Avoid overloading the washer to prevent strain on the motor and pump. Use the correct amount of HE (High Efficiency) detergent.

Expert Tip:

Some Roper washers have a diagnostic mode that can display error codes. Consult the service manual or search online for the specific model's diagnostic mode entry sequence. This often involves pressing a specific sequence of buttons on the control panel.

Frequently Asked Questions

•Where exactly is the water level sensor located and how do I access it?

The water level sensor is typically located inside the washer cabinet, near the bottom of the tub. You'll need to remove the top or side panel of the washer to access it. Consult the service manual for your specific model for detailed instructions.

•What if the drain pump tests good with a multimeter, but still seems weak?

Even if the drain pump has continuity, the impeller inside the pump housing could be damaged or worn. This can reduce the pump's ability to move water effectively. Consider replacing the pump even if it shows continuity.

•How can I tell if the MCU (Main Control Unit) is the problem?

Diagnosing an MCU issue can be tricky. Usually it is a process of elimination. Check all other components first and if everything else functions, then the MCU is likely the issue. Also, check for any visible signs of damage on the board, such as burned components or corrosion.
