I have a water pressure problem with a Grohe Lady Lux Cafe faucet
It is 4 years old & worked fine. A year ago, the pressured slowed and I removed the strainer at the end of the faucet. I also cleaned the small holes at the end of the faucet. It worked fine until now. We do have hard water, but the pressure is fine throughout the house. (The valves below the kithen sink are wide open. Is there another strainer inside the metal hose or at the ''bottom'' end which can be blocking the water flow?
Re: I have a water pressure problem with a Grohe Lady Lux...
I solved the problem by unscrewing the part of the handle which attaches to the "pullout" braided cord. There was another strainer in there which has some debris which was blocking the water flow.

On this particular faucet you may not be able to reach the part that might be giving you issues in the spray head. However, to take the head apart, on the spray face you will turn it counter clockwise, the aerator will come out at that point and you should be able to see down into the tube to see if there are any obstructions. Also if you are using the little Grohe water filter that goes into the handle before attaching the hose, it is possible that that is clogged especially after 3 years. You should be able to remove that altogether, or contact Grohe for a replacement. If once you have removed all of these and have found no removable obstructions, then the only other thing to do is contact Grohe for a replacement spray head which I believe they are still available. Hope that helps.
I have the same problem and have the fix. There is a water pressure regulator on the bottom of the faucet( under the sink) this part is bad. Grohe will replace it for free. Call Grohe at630=582=7722 tell them the model # of the faucet and the color of the regulator, they will send you a new one for FREE.
If you have the spray head type, I had the same problem...called Grohe. They said to remover the pressure regulator. Take off the spray head, and just inside the end where the water comes in, you will see a white plastice thingy. Remove it. They said you can do it with needle nose pliers, but I had to pry it our with a tiny screwdriver. It came out in pieces, but once out, the water pressure is GREAT!
it sounds like you need to up the temp on your water heater so that you are mixing more cold with the hot .be careful hot water can cause burns if valve is 4 years old then it has a limit stop do not set above 120 *you will need allen key and thermometer to check temp
I soaked the connection between the handle and the valve body in a penetrating oil for several hours and eventually used more force than I hoped to use to remove the handle. Once the handle and end cap (part 09 209) were removed, I could see that the valve assembly (part 46 048) was loose which caused water to leak from the seals (part 46 209) between the valve assembly and faucet body. So I tighted the screws that hold the valve assembly to the faucet body and the leaked stopped.
