If your kitchen sink spray nozzle is not working, the first thing to check is the water supply. Make sure that the water supply to your sink is turned on and that there are no issues with the water pressure. If there is low water pressure, it could be affecting the functionality of your spray nozzle. Low water pressure can be caused by a variety of factors including clogged pipes, water leaks, or issues with the water main. You may need to call a plumber to diagnose and fix the problem.Check the water supply
If the water supply is not the issue, the next step is to check the spray nozzle itself for clogs. Over time, mineral deposits and sediment can build up in the nozzle, causing it to become clogged and affecting its performance. To check for clogs, remove the spray nozzle from the hose and run water through it. If the water is not flowing freely, you may need to clean the nozzle to remove any buildup. Use a toothbrush or small brush to scrub away any debris and then reattach the nozzle to the hose.Check the spray nozzle for clogs
If there are no clogs present, the next thing to check for is any damage to the spray nozzle itself. Over time, the nozzle can become cracked or damaged, which can affect its functionality. Check the nozzle for any visible cracks or breaks, and if present, you will need to replace the nozzle entirely. You can find replacement nozzles at most hardware or home improvement stores.Inspect the spray nozzle for damage
The connection between the spray nozzle and the hose is another potential area for issues. Make sure that the nozzle is secured tightly to the hose and that there are no leaks or damage to the connection. If the connection is loose, tighten it with a pair of pliers. If there is damage, you may need to replace the hose or the nozzle.Check the spray nozzle connection to the hose
If none of the above solutions have fixed the issue, it may be time to replace the spray nozzle altogether. Over time, wear and tear can affect the performance and functionality of the nozzle, and it may simply need to be replaced. Be sure to choose a high-quality replacement nozzle to ensure long-lasting performance.Replace the spray nozzle
Another potential cause of a malfunctioning spray nozzle is low water pressure. If the water pressure in your home is generally low, it can affect the functionality of your spray nozzle. You may need to install a water pressure booster or call a plumber to address the issue.Check the water pressure
The aerator, which is the small mesh screen at the end of the nozzle, can also become clogged over time. To check for any buildup, unscrew the aerator and rinse it thoroughly with water. You can also use a toothbrush or small brush to scrub away any debris. Once cleaned, reattach the aerator to the nozzle and test the functionality.Clean the aerator
If the water supply and other components of the spray nozzle seem to be in working order, the issue may be with the hose itself. Over time, the hose can become kinked or twisted, which can affect the water flow. Check the hose for any visible kinks or twists, and if present, try to straighten them out. You may also need to replace the hose if it is too damaged.Check the hose for kinks
The diverter valve is responsible for controlling the flow of water from the faucet to the spray nozzle. If the spray nozzle is not working, there may be an issue with the diverter valve. To check, turn on the faucet and switch between the faucet and the spray nozzle. If the water flow is weak or non-existent when using the spray nozzle, the diverter valve may need to be replaced.Inspect the diverter valve

They will be able to diagnose and fix the issue, ensuring that your spray nozzle is functioning properly once again.
