Roper Washer Unexpected Pause During Rinse Cycle:... | appliancefaults.com

Technical Background:

The main control unit (MCU) manages the washer's cycle. It uses inputs from sensors (water level, lid switch) to control the motor, valves, and drain pump. Voltage paths are critical; a break can stop the wash cycle.

Symptoms:

The Roper washer pauses unexpectedly during the rinse cycle every time. The cycle doesn't resume until power is cycled or after an extended delay.

Possible Causes:

Faulty water level pressure switch
Clogged drain pump filter
Defective lid switch
Malfunctioning main control unit (MCU)
Damaged wiring harness causing intermittent connection
Low incoming water pressure

Solution:

1

Unplug the washer from the outlet. Locate and shut off the water supply valves to the washer.
2

Inspect the water level pressure switch. Disconnect the air hose and gently blow into the switch. Listen for a click. If there's no click, replace the switch.
3

Check the drain pump filter for obstructions. Typically located at the bottom front of the washer behind an access panel. Use a 1/4-inch nut driver to remove the panel screws. Clean the filter thoroughly.
4

Test the lid switch for continuity using a multimeter. With the lid closed, the switch should show continuity. If not, replace the lid switch.
5

Examine the wiring harness for any signs of damage or loose connections. Pay close attention to the connections near the MCU and the motor.
6

Verify the incoming water pressure is at least 20 PSI. A low pressure can cause the washer to pause waiting for the water level to reach the appropriate setting.
7

If all other components test good, the MCU may be faulty. Replacement of the MCU may be necessary, but this requires careful reprogramming or a pre-programmed replacement.

Safety Warning:

Disconnect power to the washer before performing any repairs. Use Lock-Out Tag-Out (LOTO) procedures. The washer operates on 120V AC; avoid contact with live electrical components.

Prevention:

Regularly clean the drain pump filter every 3 months. Check the inlet hoses for kinks and ensure adequate water pressure. Avoid overloading the washer.

Expert Tip:

Many Roper washers have a diagnostic mode. Press and hold the Start/Pause button for 3 seconds, then rotate the cycle selector knob one click clockwise, then one click counter-clockwise, then one click clockwise within 6 seconds. Error codes will be displayed as flashing lights on the control panel.

Frequently Asked Questions

•What is the proper water level pressure switch part number for my Roper washer model?

Locate your model number (usually inside the lid or on the back panel). Search online using your model number and "water level pressure switch part number". Several appliance parts retailers have databases.

•How do I reprogram the MCU if I replace it?

MCU reprogramming requires specialized tools and software specific to Roper washers. Consult the service manual or contact a qualified appliance technician. Many replacement MCUs are pre-programmed based on the model number.

•What is the acceptable voltage range for the lid switch circuit?

The lid switch circuit typically operates at 5V DC. Use a multimeter to check the voltage across the lid switch terminals with the lid open and closed. There should be a clear difference in voltage readings to indicate proper switch function.
