Washing Machine Is Filling With Water But Just Keeps Draining

Washing machine fills but drains at same time. If your Washer fills with water but constantly drains out, there are a few possible reasons. Most likely the water coming into the washer through the water inlet valve could be siphoned out to the drain pump and out the drain hose because of an issue with the pump or plumbing.

Washer Fills and Drains Simultaneously

When your washing machine fills with water but continues to drain at the same time, it can make you wonder what the heck is going on. This guide provides an approach to diagnose and fix this issue, beginning with the most common causes and offering detailed step-by-step solutions.

Check Water Siphoning Issues

Problem: Water siphoning is a frequent culprit when your washer drains while it is supposed to be filling. This typically occurs if the drain hose is positioned improperly.

Solution: Ensure the drain hose is not inserted too deeply into the standpipe; it should only extend 4 to 5 inches inside. Use a U-bend or a hook to secure the hose, preventing it from moving. The end of the hose must be higher than the water level in the washer to prevent gravity-induced siphoning.

Verify Water Supply and Hose Setup

Problem: Insufficient water flow due to issues in the water supply or hose setup can cause improper filling and draining.

Solution: Check that both hot and cold water faucets are fully open. Ensure there are no kinks or clogs in the hoses. Straighten any kinks and clear obstructions if found. Inspect the air gap in the drain hose for any blockages that might create a vacuum, leading to siphoning. Clear the air gap as necessary.

Inspect Water Inlet Valve and Screens

Problem: Clogged inlet screens or a faulty water inlet valve can restrict water flow, affecting the filling process.

Solution: First, turn off and unplug the washing machine. Then, disconnect the hoses at the back where they connect to the inlet screens. Remove any debris by gently brushing the screens, then rinse them thoroughly. Reconnect everything and test the machine. If cleaning the screens doesn’t resolve the issue, proceed to replace them.

If the problem may be with the water inlet valve, ensure the machine is unplugged and disconnected from the water supply. Locate the inlet valve and use a multimeter set to test for continuity. If there is no continuity, the valve is likely malfunctioning and needs to be replaced. Carefully remove the faulty valve, attach a new one ensuring all connections are secure, and test the machine to confirm the issue is resolved.

Test Washer Water Valve

Assess the Drain Pump and Pressure Switch

Problem: A continuously running drain pump or a faulty pressure switch can mistakenly drain water.

Solution: Listen to determine if the drain pump is active when it shouldn’t be, which suggests overfilling or a control issue. Inspect the pressure switch by disconnecting it and checking its continuity with a multimeter. If the switch fails the test, replace it and recheck the system to ensure that the issue has been corrected. If your washing machine displays error codes, consult the manufacturer’s website to decipher these codes and address the specific faults indicated.

Evaluate the Washer’s Timer and Electronic Controls

Problem: The timer or electronic control panel might fail to correctly signal the start of the fill cycle.

Solution: Carefully examine the timer or control panel for any visible signs of damage or malfunction. If your machine displays error codes, refer to your washing machine’s manual to understand whether these relate to the timer or electronic controls. If you find issues with these components, they may need to be repaired or replaced. Follow the manufacturer’s instructions for replacing these parts, or contact a professional if the repair seems too complex.

If after following these detailed steps your washing machine fills and drains simultaneously, it might be time to consult a professional. Complex issues with the machine’s internal electronics or mechanical systems may require expert diagnosis and repair. Remember, proper maintenance and regular checks can help prevent such issues from developing in your washing machine.

Inspect the Air Dome Tube

Problem: The air dome tube might also be contributing to the draining issues if it’s damaged or obstructed.

Solution: Inspect the air dome hose carefully for any signs of cracks, damage, or obstructions. Remove the hose and submerge it in a bucket of water. Seal one end of the hose and blow into the other end. If you see bubbles forming, this indicates that there are holes or cutouts in the hose, and it should be replaced. If there are no bubbles, ensure that there are no internal obstructions. Clean out any debris or clogs within the hose as needed.
