Roper Washer Beeping 4 Times During Wash Cycle:... | appliancefaults.com

Technical Background:

The washer's MCU monitors various sensors and components. The 4-beep error typically indicates a problem with the motor or drain system. The MCU sends voltage to the motor and drain pump, and receives feedback signals. If the MCU detects an unexpected voltage drop, current surge, or loss of signal, it triggers the error code.

Symptoms:

The Roper washer stops mid-cycle and beeps four times. The washer may or may not drain. The drum may or may not be filled with water. The error occurs randomly, and sometimes the washer completes a cycle without issue.

Possible Causes:

Clogged drain pump or drain hose
Failed pressure switch
Motor control unit (MCU) malfunction
Locked rotor on the motor
Wiring harness issue between MCU and motor
Obstruction in the tub preventing spinning

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Check the drain pump for obstructions. Remove the pump access panel (usually at the bottom front) and inspect for socks, coins, or other debris. Use a 5/16-inch nut driver to remove screws.
3

Inspect the drain hose for kinks or clogs. Disconnect the hose from the drainpipe and the pump, and flush with water to remove any obstructions.
4

Examine the pressure switch and its hose. The pressure switch is usually located near the top of the washer. Check the hose for cracks or kinks.
5

Test the motor windings for continuity. Use a multimeter to check the resistance of each winding. Refer to the service manual for correct resistance values.
6

Inspect the wiring harness between the MCU and the motor for loose connections or damage.
7

If the problem persists, suspect a faulty MCU. Replacement may be necessary.

Safety Warning:

Disconnect power to the washer before performing any repairs. Lock Out/Tag Out (LOTO) procedures should always be followed. Some components may retain a high voltage charge even after the power is disconnected.

Prevention:

Regularly clean the drain pump filter (if accessible) and inspect the drain hose for kinks. Avoid overloading the washer with excessive laundry.

Expert Tip:

Check the diagnostic codes stored in the washer's memory. To enter service mode, rapidly press the START button six times within 12 seconds. This may display more specific error codes to aid in troubleshooting.

Frequently Asked Questions

•What is the correct resistance range for the motor windings on this Roper washer?

The correct resistance range varies depending on the motor model. Refer to the washer's service manual or the motor's nameplate for specific values. A typical range is between 3 and 10 ohms per winding.

•How do I access the drain pump on this model Roper washer?

The drain pump is typically accessible from the front of the washer. Unplug the washer, then locate the access panel at the bottom front. You might need to use a flathead screwdriver to pry it open or remove screws with a 5/16-inch nut driver. The drain pump will be behind this panel.

•If the pressure switch hose is clear and undamaged, how do I test the pressure switch itself?

You can test the pressure switch using a multimeter set to measure continuity. Disconnect the wires from the pressure switch and blow gently into the hose connection. Check for continuity between the terminals. Refer to the wiring diagram or service manual to determine the correct terminal combinations for different pressure levels (empty, filled).
