If your Grohe kitchen faucet malfunctions, there is a basic repair that will fix it. This repair involves replacing the cartridge with a new one from Grohe. Since Grohe faucets have specially designed parts, only a Grohe cartridge for your model will do the trick. Order this part from a plumbing supply store or a hardware store in your area. This repair takes about half an hour if you are experienced with home repairs.
Pull Down Faucets
Pull down faucets from Grohe include the Eurostyle lines. These faucets have a pull down sprayer head that returns to the spout mouth when not in use. If this part of the faucet malfunctions, first clean the nozzles with clear water to loosen and remove built-up sediments. Then replace the nozzle with a new part from Grohe. Detach the nozzle by turning it counterclockwise and disconnecting it, then snap the new hose into place.
Single Handle Kitchen Faucets with No Sprayer
A single handle Grohe kitchen faucet has no pull down sprayer attachment, just a spout that delivers water from the faucet body, like the Essence model. If this part leaks or does not perform correctly, change out the cartridge inside the handle base. Take off the handle by unscrewing the set screw on the base of the handle. This screw is right under the lever on the handle. Use an Allen wrench to take out the screw, pull out the handle and then unscrew the dome cap and retaining nut with a pair of pliers. Remove and replace the cartridge and then reassemble the faucet handle.
Grohe Side Handle Faucets
Some Grohe faucets have a handle mounted on the side of the handle base. This includes the Ladylux Pro faucet and Concetto series. To change the cartridge on this type of faucet, there are no special steps to take. The only difference is the location of the set screw and handle. You will find the set screw on the side of the handle base. Unscrew it with an Allen wrench and pull the handle off. Unscrew the dome-shaped cover and retainer nut and remove the cartridge. Replace the cartridge with a new one and reassemble the faucet.
Other Considerations
If another part of the faucet malfunctions, consider these options. Test both water supply valves, and turn each to the full on position. If one or more of the valves is partially closed, the faucet experiences low water pressure. The sprayer may not work in the Grohe faucets with sprayers or pull out spray nozzles. If leaks exist below the faucet from the supply lines, turn the water valves off, unscrew the supply hoses from the faucet and water pipes. Replace them with new supply hoses and turn the water back on.
