Roper Washer Taking Too Long to Fill: Troubleshooting... | appliancefaults.com

Technical Background:

The Roper washer's fill cycle is controlled by the main control unit (MCU). The MCU energizes the water inlet valve solenoids based on input from the pressure switch, which monitors the water level in the tub. Voltage is sent from the MCU to the valve, usually 120V AC. If the MCU, pressure switch, or inlet valve malfunctions, the fill time can be affected.

Symptoms:

The Roper washing machine is taking an excessively long time to fill with water during the wash cycle. This can result in extended cycle times and potentially affect wash performance. The water may trickle in or fill very slowly.

Possible Causes:

Kinked or blocked water supply hoses
Clogged inlet valve screens
Low water pressure to the house
Defective water inlet valve
Faulty pressure switch or air dome obstruction
Malfunctioning main control board (MCU)

Solution:

1

Turn off the water supply valves behind the washer.
2

Disconnect the water supply hoses from the fill valves.
3

Inspect the inlet valve screens for debris. Clean or replace if necessary.
4

Reconnect the hoses and turn the water supply back on. Check water pressure.
5

Disconnect power to the washer. Use a multimeter to test the water inlet valve solenoids for continuity. A reading of approximately 1000-1300 ohms is typical; open circuit means the valve needs replacement.
6

Check the pressure switch and air dome for blockages. Disconnect the small hose from the pressure switch and blow into it to ensure it is clear.
7

If all else fails, suspect a faulty main control board (MCU). Replacement may be necessary.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the washer cannot be accidentally powered on during maintenance. 120V AC is present in several components; exercise caution.

Prevention:

Regularly inspect and clean the water inlet valve screens. Check water supply hoses for kinks or damage. Periodically run a washer cleaner cycle to prevent buildup in the internal components.

Expert Tip:

Some Roper washers have a diagnostic mode that can display error codes related to the fill cycle. Consult the service manual or online resources for instructions on entering diagnostic mode. Often this involves pressing a specific sequence of buttons on the control panel.

Frequently Asked Questions

•What is the proper water pressure for a washing machine?

The ideal water pressure for a washing machine is typically between 20 and 100 PSI. Low water pressure can significantly impact fill times.

•How do I test the pressure switch on my Roper washer?

Disconnect the power to the washer. Locate the pressure switch, usually near the bottom of the tub. Use a multimeter to test for continuity between the terminals as you gently blow into the air hose connected to the switch. The resistance should change as the pressure increases.

•Where can I find a replacement water inlet valve for my Roper washing machine?

Replacement water inlet valves can be found at appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have the model number of your washing machine available to ensure you get the correct part.
