Introduction

It’s frustrating when your washing machine starts but won’t fill with water, instead draining immediately. This prevents you from doing laundry and can be caused by a few common issues. Addressing this quickly is important to prevent potential water damage and avoid the inconvenience of a non-functional appliance. Let’s walk through how to troubleshoot and potentially fix this problem yourself!

Common Causes of Washing Machine Won’t Fill & Keeps Draining

Here are several common reasons why your washing machine might be filling and draining at the same time:. For more related activities, check out our Whirlpool Front Load Washer Won T Spin Fast.

• Drain Hose Too Low: The drain hose might be inserted too far down the drainpipe, creating a siphoning effect.
• Siphoning Action: Improper drain hose installation or a loose connection can create a siphon that continuously drains the water.
• Faulty Drain Valve/Pump: The drain valve or pump might be stuck open, allowing water to drain as it enters.
• Clogged Drain Pump Filter: A blockage in the drain pump filter can sometimes interfere with proper water level control.
• Pressure Switch Problems: The pressure switch, which senses the water level, might be malfunctioning and incorrectly signaling the machine to drain.
• Air Lock in Drain Hose: Sometimes an air pocket in the drain hose can trigger premature draining.
• Control Board Malfunction: In rare cases, a malfunctioning control board can cause erratic behavior, including simultaneous filling and draining.
• Incorrect Hose Connections: Double-check that the hot and cold water hoses are connected to the correct inlets on the back of the machine.

Symptoms Checklist

Confirm these symptoms to accurately diagnose the problem:

• The washing machine starts as usual.
• Water starts to enter the drum.
• Almost immediately (or shortly after), the water begins to drain.
• The drum never fills to the appropriate level.
• You might hear the drain pump running constantly, even when it should be filling.

How to Fix Washing Machine Won’t Fill & Keeps Draining Step-by-Step Guide

Follow these steps in order to try resolving the issue:

1. Unplug the Washing Machine: For safety, always disconnect the power before working on any appliance.
2. Check the Drain Hose Height: Ensure the top of the drain hose is at least 30-36 inches above the floor. Use a zip tie to secure it.
3. Inspect the Drain Hose Insertion: Make sure the drain hose isn’t pushed too far down into the drainpipe (ideally no more than 6 inches).
4. Check for Kinks or Blockages in the Drain Hose: Straighten any kinks and remove the hose to check for obstructions.
5. Clear the Drain Pump Filter: Locate the drain pump filter (usually at the bottom front of the machine). Remove it and clean out any lint, debris, or small objects.
6. Inspect the Drain Hose Connection: Ensure that drain hose connection to the machine’s drain outlet is secure and properly sealed.
7. Check the Pressure Switch Hose: Locate the small hose connected to the pressure switch. Make sure it is securely attached and free from kinks or obstructions. This hose senses the water level.
8. Run a Calibration Cycle (if applicable): Some washing machines have a calibration cycle that can reset the water level settings. Refer to your owner’s manual.
9. Check Water Inlet Valves: Make sure both hot and cold water inlet valves are fully open. Close and reopen a few times in case they’re partially stuck.
10. Check Water Pressure: Ensure sufficient water pressure is reaching the machine by testing the water flow at the faucet.
11. Look for Leaks: Examine hoses and connections for any signs of leaks that might be causing a pressure drop.
12. Run an Empty Cycle: After completing the previous steps, run an empty cycle to see if the problem is resolved.
13. Power Cycle the Machine: Unplug the machine for 5 minutes, then plug it back in. This can sometimes reset the internal computer.

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free methods:

• Reset the Machine: As mentioned, unplug the washing machine for several minutes.
• Clean the Drain Pump Filter: Regularly clean the drain pump filter to prevent blockages.
• Inspect Hoses: Routine inspection of hoses for kinks, cracks, or leaks is important.
• Maintain Proper Drain Hose Height: Ensure correct drain hose setup to avoid siphoning.
• Recalibrate (if possible): Use your machine’s calibration cycle, if available.

When Replacement Might Be Necessary

If the troubleshooting steps above don’t solve the problem, a faulty drain valve or a malfunctioning pressure switch might be the culprit. Replacing a drain valve might cost between $50-$150 (USD), and a pressure switch replacement could be in the $40-$100 (USD) range. In rare instances, a control board failure may require replacing the entire board, which could cost $150-$300 (USD) or more. Contacting a qualified technician for diagnosis and repair is recommended before replacing these components.

Safety Warning

• Always unplug the washing machine before attempting any repairs.
• Avoid working with water near electrical components.
• Be careful when handling tools to prevent injury.
