Step 1: Turn off the water supply to the faucet

The first step is to turn off the water supply. You can do this either from the bathroom sink or from the primary source of your water supply to the house. This step is necessary to prevent unnecessary water spillage, especially as the water flow runs through the cartridge.

Step 2: Loosen the nuts that hold the supply lines

Next, lift the faucet lever to access the screws. Use an Allen wrench to loosen the nuts holding the water lines in place. Pull the water lines away from the faucet once the nuts are out of the way.

Step 3: Remove the cartridge cover

With the Allen wrench, unscrew to remove the plastic that covers the cartridge. You will also have to remove the small cap after dismantling the lever.

Remove the cap to unscrew the nut holding down the cartridge. Use an adjustable spanner to remove the nut by turning the spanner counterclockwise.

Step 4: Remove the cartridge

Now it should be easy to remove the cartridge. Simply pull it out. You don’t need any tool to do this. Next, inspect the cartridge to determine if it needs cleaning or a replacement.

Removing the cartridge may expose some debris or build-up of dirt in and around the basin. Whether the cartridge is to be replaced or just cleaned, it is appropriate to clean the entire faucet basin and all faucet parts.

How To Replace The Cartridge

If the cartridge is damaged, you will need to replace it because cleaning won’t solve the problem. Here is how to replace the cartridge in a Grohe bathroom faucet.

Step 1: Reinstalling your cartridge

First, observe the cartridge to be sure it is adequately sealed. Once this is done, fix it into the cleaned basin. Be sure the cartridge is correctly placed by lining up the two tabs to serve as a guide. This will prevent misalignment.

Correctly aligning the cartridge is the most essential step in replacing it. If it is not aligned correctly, it will not work and can also damage the other parts during installation.

Step 2: Assembling your Grohe faucet

Now that you’re done replacing your cartridge and cleaning the basin, it is time to reassemble your Grohe faucet.

The procedure is the same. Again, simply follow the steps for dismantling the faucet, but this time, do it in reverse order.

Here’s what you need to do:

  • Once your cartridge is safely installed, you will need a 32mm box spanner. Screw the nut, applying moderate pressure. Be careful not to screw it too tightly, as that can damage the new or repaired cartridge.
  • Replace all the coverings of the cartridge. Next, put the lever back on and use the Allen wrench to screw it, turning the key clockwise. Once it is well screwed in (be careful not to make it too tight), replace the cap. Once this is done, the internal system is secured.
  • Replace the water supply lines and screw them back into position. You can then turn on the water supply.

You have done a fantastic job, and your Grohe faucet is back to its best working condition.
