Washer Fills Up Then Stops

Introduction

Is your washing machine filling with water, only to suddenly stop before the wash cycle even begins? This frustrating issue, where the washer fills up then stops, can leave your clothes dirty and your laundry routine in disarray. It’s a common problem that can stem from a variety of causes, ranging from simple fixes to more complex issues. Addressing it quickly is important to prevent potential water damage and ensure your washing machine operates correctly, saving you time and money.

Common Causes of Washer Fills Up Then Stops

Here are some of the most frequent reasons why your washer might be filling and then stopping:

• Kinked or Blocked Water Inlet Hoses: The hoses that supply water to your washer can become bent, restricting water flow.
• Clogged Inlet Valve Screens: Small screens in the inlet valves filter debris, but they can become clogged, reducing water pressure.
• Low Water Pressure: Insufficient water pressure from your home’s plumbing can prevent the washer from filling properly.
• Faulty Water Inlet Valve: This valve controls the flow of water into the washer. If it’s malfunctioning, it might not open or close correctly.
• Pressure Switch Issues: The pressure switch senses the water level. If it’s faulty, it might prematurely signal the washer to stop filling.
• Air Lock: Air trapped in the water lines can disrupt the filling process.
• Control Panel Malfunction: Occasionally, the control panel can experience glitches causing fill errors.
• Drain Hose Issues: If the drain hose is too low, water might siphon out as the washer fills, triggering it to stop.

Symptoms Checklist

Use this checklist to help pinpoint the issue:

• Washer starts filling normally.
• Water stops flowing into the washer before the drum is adequately filled.
• The washer may or may not display an error code.
• The wash cycle does not start.
• You may hear humming noises.
• Water trickles in slowly, then stops.
• The problem occurs with both hot and cold water.

How to Fix Washer Fills Up Then Stops Step-by-Step Guide

Here’s how to troubleshoot the “washer fills up then stops” problem:

1. Check Water Supply: Make sure both hot and cold water supply valves behind the washer are fully open.
2. Inspect Inlet Hoses: Look for kinks, bends, or damage in the water inlet hoses. Straighten any kinks.
3. Clean Inlet Valve Screens: Turn off the water supply. Disconnect the inlet hoses from the washer. Locate and clean the small screens inside the inlet valve openings with a small brush.
4. Test Water Pressure: Connect a hose to the water supply valve and check the water pressure. It should be a strong, steady stream.
5. Check Drain Hose Height: Ensure the drain hose is properly positioned, usually between 30-36 inches above the floor. It shouldn’t be inserted too far into the drain pipe.
6. Check for Air Lock: Turn off the water supply, disconnect the inlet hoses, and point them into a bucket. Briefly turn on the water to flush out any air. Reconnect the hoses.
7. Reset the Washer: Unplug the washer from the power outlet for 1-2 minutes. Plug it back in and try running a test cycle. This can reset the control panel.
8. Check the Pressure Switch Hose: Locate the small hose connected to the pressure switch. Make sure it is securely connected and free from kinks or blockages.
9. Run a Calibration Cycle (if applicable): Some washers have a calibration or self-test cycle. Consult your owner’s manual for instructions on how to run it.
10. Listen for Unusual Noises: When the washer is attempting to fill, listen closely for any unusual noises, such as a loud humming or clicking sound. This could indicate a failing water inlet valve.
11. Check the Washer’s Filter: Some washers have a filter that can become clogged. Check your user manual to determine if yours has one and how to clean it.

Fix the Issue Without Buying Parts

Often, you can resolve the “washer fills up then stops” issue without replacing any parts:

• Washer Reset: As mentioned above, unplugging the washer for a couple of minutes can often clear minor electronic glitches.
• Hose Cleaning: Regularly inspect and clean inlet hoses to prevent blockages.
• Pressure Switch Hose Check: A simple visual inspection of the pressure switch hose can reveal kinks or disconnections.
• Filter Cleaning: Regularly cleaning the washer’s filter will allow it to function properly.
• Water pressure check: Low water pressure from your home’s plumbing can be detected by simply running water and observing the strength.

When Replacement Might Be Necessary

In some cases, replacement may be required:

• Faulty Water Inlet Valve: If the valve is humming loudly or completely unresponsive, it may need to be replaced. Cost: $30 – $100.
• Malfunctioning Pressure Switch: If the pressure switch consistently gives incorrect readings, replacement may be necessary. Cost: $20 – $80.

Safety Warning

Take these precautions before troubleshooting:

• Always unplug the washing machine from the power outlet before performing any repairs.
• Turn off the water supply valves to prevent accidental flooding.
• Be careful when working with water to avoid electric shock.
• Wear appropriate safety glasses and gloves.
