Grohe Kardoes ceramic 46 mm silkmove replacement

Sander Rosien

In this example, we explain how to replace the 46mm Grohe Eurodisc cartridge in a leaking Grohe 33770000 kitchen mixer tap. In this example, we use the Grohe 46mm cartridge and a regular Phillips-head screwdriver and 3mm Allen key as tools.

Step 1

This is the starting situation: we have a dripping Grohe tap and have determined that we need to replace the Grohe 46mm cartridge.

Step 2

First, you need to remove the handle by removing the grey cap.

Step 3

Next, you can unscrew the handle with a 3mm Allen key.

Step 4

Now that the handle is off, the cover cap must be removed. How it is attached varies by tap model, but in this case, it is clamped with a rubber seal. You can remove it by turning it a quarter turn by hand.

Step 5

Once the cover is removed, the Grohe 46mm cartridge becomes visible. It is glued on top of the tap with a metal plate and two Phillips-head screws (these are also supplied in two lengths).

Step 6

Now we can remove the Grohe 46mm cartridge by unscrewing the 2 screws.

Step 7

Now that the screws are loose, the Grohe 46mm cartridge can be removed from the tap.

Step 8

Before installing the new Grohe 46mm cartridge, we thoroughly clean the seat where it will sit. We usually use GrohClean for this.

Step 9

Now we can place the new Grohe 46mm cartridge. Pay close attention to the tabs on the bottom; they fit exactly into the recesses in the seat.

Step 10

Now we can secure the Grohe 46mm cartridge. It is important that you tighten the screws alternately. So do not tighten the left side completely first and then the right; otherwise, it will be overtightened, which is bad for the internal components. Tight is tight.
