No Water After Changing Water Filter

If you’ve recently changed your water filter and now have no water coming out, there are a few possible causes to consider. Make sure the filter is correctly installed and that all connections are secure. If it’s still not working, check to see if the water supply valve has been closed or is not fully open. You may also want to check and ensure the shutoff valve on the inlet side of the filter housing is open.

Why There Is No Water After Changing The Water Filter?

  • Incorrect installation: The most common cause of no water after changing the filter is incorrect installation. This can include not tightening the connections properly, using an incorrect size filter and not seating it correctly, or using a damaged filter.
  • Air-blocked filter: If no water comes out after changing the filter, it could be due to an air-blocked filter. To fix this issue, disconnect the flexible hoses from the inlet and outlet ports at the back of the filter housing.
  • Incomplete removal of packaging: If the filter is not working, it can be due to incomplete installation. It is essential to ensure that all packaging has been removed from the new filter before installation. This can be easily overlooked when changing a filter, but failure to do so can prevent water from flowing through the system correctly and may cause blockage.
  • Blockage in the filter housing area: If you have changed the water filter and still experience no water flow, there may be another issue. Check the filter housing area for any blockages or loose connections that can disrupt your drinking water supply.
  • Broken valve: If the water filter was recently changed, it is possible that the valve was not correctly shut after installation and may be allowing some of the water to escape. To remedy this issue, check that the valve is completely shut, and then try running water through your faucet again.
  • Damaged filter: If you are still experiencing no water, it is possible that the filter was damaged. This can happen if the filter is not handled correctly during installation or if it has been stored improperly before installation. Check the filter for any visible signs of damage and replace it with a new one if necessary.
  • Faulty new filter: If you notice no water coming out, it could be because the new filter is faulty. Check the installation instructions with the new filter to ensure proper installation, and then try reinstalling it. If that does not work, check if your old filter works again.
  • O-ring, seal, or rubber gasket not appropriately fitted: If the O-ring, seal, or rubber gasket has not been fitted correctly when changing your water filter, it can cause a leak which will mean you have no water coming through.
  • Dry filter: If there is no water after changing the filter, ensure that the o-rings on both the inlet and outlet sides are correctly installed. Check if they are dry and fit tight in their grooves.
  • Water pressure is too low: If the water pressure is too low after changing the filter, check your shutoff valve. Make sure that it is open and supplying full water flow. If it’s not, adjust accordingly.
  • Locked controls: If your refrigerator controls are locked, turn them back on to ensure that water will flow from the dispenser. To lock or unlock the controls, press and hold the “LOCK” button for three seconds.
  • Your water filter may be too loose or tight: It should be installed snugly with no more than a quarter turn of force. If too loose, water can bypass the filter and not be properly filtered.
  • Not Enough Time Has Passed: After changing a water filter, you may also need to wait before the water runs correctly again. Depending on the type of filter and how long it needs to pre-soak, this could be anywhere from a few minutes to several hours. If not enough time had passed between when you changed the filter and when you tested it, the water might not be running correctly.

How To Solve The Issue?

  • Check the mode on display: If the display is on water mode and shows no more than 1.5L of water remaining, you need to reset the filter.
  • Ensure that the water filter is installed correctly: Make sure that the water filter is installed properly and securely. If it is not, air can enter and prevent water from flowing into the system.
  • Check for any clogs: Check for any blockages in the hose or pipe associated with the water filter, as this can be causing the issue. If so, clean it out thoroughly and replace the filter.
  • Check the water line connection and the valve position: Make sure that the water line connection is turned on and in a locked position. Additionally, check the valve position to ensure that it is opened correctly.
  • Replace the filter if necessary: If the above steps do not fix the issue, it’s time to replace the water filter. Make sure to use an original filter provided by the manufacturer to ensure that your water system works optimally.

It depends on the type of filter you’re using and how often you’re using it, but a RO water filter should be changed every 6-12 months for optimal performance. If you notice any changes in the taste or quality of your drinking water, change the filter sooner.

Can a water filter cause an ice maker not to work?

Yes, if the water filter is not changed regularly, it can cause the ice maker to stop working. When a water filter becomes blocked or clogged with contaminants, such as sediment and rust particles, it reduces the water flow to the ice maker. This decrease in pressure means that there will be no cold water available for making ice cubes.

When you replace your water filter, the indicator will reset. It will monitor the amount of water passing through the filter and track it over time. Depending on the type of filter, this may measure in gallons or another unit of measurement. When too much water has passed through for a given period, it will trigger an alert that it’s time to replace your filter.

What happens if you do not change your water filter?

Not changing the filter can create several issues. The most obvious issue is that it will eventually become clogged, making water flow through your system slower and reducing its effectiveness at filtering contaminants. Additionally, not replacing the filter can cause bacteria to grow in your system, leading to potential health risks for anyone using the affected water source.


If you have recently changed your water filter, it is essential to ensure that the connection is secured correctly and that no air or water pressure has been lost. You might also want to check whether any parts of the filter are loose or missing. If all of these elements are in place and you still don’t have any water coming out of the filter, it is advisable to call a professional for assistance.
