Roper Washing Machine Error Code Ld: Long Drain Error... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors the water level and drain time. If the water level sensor indicates water is still present after a specific drain time (typically several minutes), the MCU triggers the 'Ld' error. Voltage is supplied to the drain pump motor via a relay controlled by the MCU. The pressure switch provides feedback to the MCU regarding the water level.

Symptoms:

The washing machine displays the error code 'Ld' and fails to drain water properly. The wash cycle may stop prematurely, leaving clothes soaked.

Possible Causes:

Blocked drain pump
Kinked or clogged drain hose
Defective drain pump motor
Clogged air dome
Standpipe too high or restricted
Failed pressure switch

Solution:

1

Disconnect power to the washing machine by unplugging it from the outlet or switching off the breaker in the breaker panel.
2

Inspect the drain hose for kinks, clogs, or damage. Remove the hose from the standpipe and flush it with water to clear any obstructions.
3

Access the drain pump, typically located behind an access panel at the bottom front or rear of the washer. Use a 1/4-inch nut driver to remove the panel.
4

Disconnect the hoses connected to the drain pump. Be prepared for some water spillage. Inspect the pump impeller for obstructions like lint, coins, or buttons.
5

If no obstructions are found, test the drain pump motor using a multimeter. Set the multimeter to measure resistance (Ohms). Disconnect the wires to the drain pump and measure the resistance across the terminals. A typical reading should be between 10 and 30 Ohms. An open circuit (OL) indicates a faulty motor.
6

If the drain pump is faulty, replace it with a new one.
7

Reassemble the washing machine and test it to ensure the 'Ld' error is resolved.

Safety Warning:

Always disconnect the power supply to the washing machine before performing any repairs. High voltage is present when the machine is plugged in. Use Lock-Out/Tag-Out (LOTO) procedures to prevent accidental energization.

Prevention:

Regularly clean the lint filter and inspect the drain hose for kinks or clogs. Avoid overloading the washing machine, as this can contribute to drain problems. Periodically run an empty wash cycle with a washing machine cleaner to prevent buildup.

Expert Tip:

Some Roper washing machines have a diagnostic mode that allows you to run a drain test. Consult the service manual for the specific sequence to enter diagnostic mode and run the drain test. This can help pinpoint if the drain pump is functioning correctly.
