Kohler Faucet Cartridge Stuck [Easy Solutions]

One common problem that Kohler faucet owners encounter is a stuck cartridge. The cartridge is a crucial component within the faucet that controls the flow of water. But If it gets stuck, it can cause a significant inconvenience.  

Don’t panic, here we have a few quick tips for you to loosen the cartridge from your shower faucet:

i). Use A Hairdryer:

This is one of the most effective methods you can try out. Basically, metals tend to expand when hot, and that’s the point a hair dryer or heat gun comes into play. Simply put a hair dryer on the stuck cartridge for about 8-10 minutes on high heat. With more heat, the faucet metal will expand and loosen the cartridge. 

ii). Using Socket Wrench:

You can use a socket wrench to remove the stubborn cartridge. Try to slide the wrench over the stem and turn it counterclockwise to remove the cartridge retaining nut.

When done, gently pull out the cartridge without damaging the other faucet parts.

iii). Using A Cartridge Puller:

As one effective tool, you can use a cartridge puller to remove the stuck cartridge from the valve stem.

For instance, place the puller over the stem and grip the handle of the puller. Now, twist the puller back and forth to pull the cartridge straight out. 

iv). Loosen With Vinegar Solution:

If the cartridge puller doesn’t work, you can apply the vinegar solution as one of the more effective ways to soften the cartridge. Simply inject the vinegar into the valve housing using a syringe and let it sit overnight to dissolve the scale build-up. In the morning, hope you will be able to extract the cartridge. 

v). Use Lubricant Like WD-40:

If you’re still struggling with the Rust and scale build-up in the valve stem, try to dissolve it with WD-40 or a similar spray.

Spray the WD-40 on the valve connection and  Give it 10 minutes to work. Then, try to unscrew the cartridge. 

vi). Use A Screw Extractor:

In case you’re suspecting of broken screws on the cartridge assembly leading to being stuck, you can use a screw extractor to remove the broken part and cartridge.

For instance, drill up to ½ tap into the center of the cartridge with the screw extractor. When done, use pliers to pull out the cartridge. 

Why Does A Kohler Faucet Cartridge Stuck [Why + How To Fix]

Let’s check out why the bathroom faucet stuck:

1. Kohler Faucet Cartridge Clogged

Kohler faucet cartridges primarily stuck due to the accumulation of minerals and sediment within the cartridge. Even the issue is quite common in areas with hard water, which contains high levels of minerals such as calcium and magnesium.

When water flows through the cartridge, these minerals can gradually deposit and build up on the internal components, including the moving parts of the cartridge. 

Over time, this buildup restricts the smooth movement of the cartridge, making it difficult to turn or remove.

Quick Fixes:

In order to fix a Kohler faucet cartridge that has become stuck due to clogged, follow these steps:

Step 1: Turn Off The Water Supply:

First up, you’ll need to turn off the water supply to avoid any accidental leaks or flooding.

Step 2: Disassemble The Faucet:

Remove any decorative caps or handles that cover the cartridge. Simply unscrew or pry off the handle with a flathead screwdriver. Once removed, you will have access to the cartridge.

Step 3: Soak The Cartridge:

Now at this stage, you will need to prepare a vinegar solution to dissolve the minerals. Pour vinegar with equal parts of water into a container large enough and inject the solution into the cartridge with a syringe. 

Let it soak for several hours or overnight. The vinegar helps dissolve the mineral buildup and break it apart.

Step 4: Pull Out The Cartridge:

After soaking, it will be quite easier for you to pull out the cartridge from the assembly. 

Note: Remember, if you’re unsure about any step or encounter difficulties, it’s recommended to consult the manufacturer’s instructions or seek assistance from a professional plumber to avoid any further damage to your faucet.

• When you’re applying too much force to the faucet handle can strain or warp the cartridge, causing it to become stuck.
• Over time, the moving parts of the cartridge can wear down or become damaged, leading to sticking or seizing.
• In rare cases, a faulty or poorly manufactured cartridge may have inherent warping or damage that causes it to become stuck.

In the case of a damaged or warped cartridge, the following solutions may be helpful:

Apply steady and controlled pressure to loosen the cartridge gradually.

Step 4:  If the cartridge remains stuck even after it has been properly loosened, you can apply a lubricant. Such as silicone grease or plumber’s grease, to the cartridge. This can help reduce friction and make it easier to remove. Apply a small amount of lubricant to the cartridge and gently try to twist and remove it.

Step 5:  If you are unable to loosen the cartridge or if you are unsure about any step, it is advisable to seek assistance from a professional plumber. 

They have the expertise and tools to handle the situation safely and effectively. A plumber may also be able to identify and address any other underlying issues causing the cartridge to stick.
