Washer overflows. What causes the washing machine to overflow and how do I fix it myself?
What can cause your washer to overflow?
Clogged water inlet valve
A clogged water inlet valve can prevent water from flowing into the washing machine, causing it to overflow and drain constantly. Dirt, sediment, and debris can accumulate inside the valve, restricting water flow.
Faulty water level control
The water level control is responsible for monitoring the water level inside the washing machine. If it’s malfunctioning, the machine may not stop filling with water, leading to an overflow and constant draining.
Damaged pressure switch
A damaged pressure switch can also cause a washing machine to overflow and constantly drain water. The pressure switch senses the water level and turns off the water supply when the desired level is reached. If it’s not working correctly, the machine may not stop filling.
Blocked pressure hose
The pressure hose connects the pressure switch to the tub. If the hose is blocked, kinked, or damaged, it can affect the pressure switch’s ability to accurately measure the water level, leading to overflow and constant draining issues.
Malfunctioning drain pump
The drain pump is responsible for removing water from the washing machine. If it’s not functioning properly, the machine may not be able to drain water correctly, causing it to overflow.
Overloading the machine
Filling the washing machine with too many clothes can obstruct the proper flow of water, leading to an overflow. It is crucial to follow the recommended load capacity for your specific machine to prevent this issue.
Inadequate water supply pressure
Low water supply pressure can lead to imbalances in the washer’s drainage system, causing it to overflow. Ensuring that the water supply pressure is adequate can help prevent this issue.
Here are ways to fix your overflowing washer
Step 1: Inspect the water inlet valve
Turn off the water supply to the washing machine and disconnect the power. Remove the hoses connected to the water inlet valve and inspect it for any debris or clogs. Clean the valve using a toothbrush and a mixture of water and vinegar. Reattach the hoses and turn on the water supply to check if the issue is resolved.
Step 2: Check the water level control
Disconnect the power and locate the water level control, usually found behind the control panel. Inspect it for any visible damage or loose connections. If necessary, replace the water level control with a new one.
Step 3: Test the pressure switch
To test the pressure switch, disconnect the power and remove the control panel. Locate the pressure switch and remove the hose connected to it. Blow air into the hose to ensure it’s not blocked. Reconnect the hose and test the pressure switch with a multimeter. If the switch is faulty, replace it with a new one.
Step 4: Examine the pressure hose
Inspect the pressure hose for any kinks, damage, or blockages. If the hose is damaged, replace it with a new one. If it’s blocked, clean it with a long brush or a pipe cleaner.
Step 5: Inspect the drain pump
Disconnect the power and locate the drain pump, usually found at the bottom of the washing machine. Check for any visible damage, debris, or clogs in the pump. If necessary, replace the drain pump with a new one.
Step 6: Do not overload washer
When loading your washing machine, be careful not to overload it. Do not add large blankets in with regular clothing. Wash large items separately. An overloaded washer can cause an overflow from just simply too many items in the drum. Overloads can cause water to overflow and cause problems and flooding.
Step 7: Water pressure to washer
The water pressure going to the washer can cause an overflow if it is too low. What happens is the water inlet valve does not receive the signal to turn off and stop the flow of water. So check that the water pressure is sufficient. Usually 20 to 25 psi and up is needed.
Preventive maintenance for washing machine
Clean the water inlet valve regularly
Regularly inspect and clean the water inlet valve to prevent clogs from forming. This will ensure that the valve operates efficiently and helps avoid overflow and constant draining issues.
Avoid overloading the washing machine
Overloading the washing machine can cause the water level to rise above the intended limit, leading to overflow and constant draining problems. Always follow the manufacturer’s guidelines for load capacity.
Use the correct detergent
Using the wrong type of detergent can create excessive suds, which can cause the washing machine to overflow. Always use the detergent recommended by the manufacturer for your specific machine.
Regularly inspect hoses and connections
Check hoses and connections for any signs of wear, damage, or leaks. Replace damaged hoses and tighten loose connections to prevent water from overflowing and constantly draining.
Schedule regular maintenance
Regular maintenance can help identify potential issues before they become significant problems. Consider scheduling a professional maintenance check for your washing machine every year to ensure it operates efficiently and to avoid overflow and constant draining issues.
