there may be an issue with the hose or the weight that is attached to the hose under the sink. Here are some steps you can follow to troubleshoot the issue:

1. Check the weight: There should be a weight attached to the hose under the sink. This weight is designed to help the hose retract back into the faucet. If the weight is loose or not in the correct position, it can affect the retracting ability of the hose. Make sure the weight is securely attached to the hose and is in the correct position.
2. Check the hose for obstructions: The hose may not be retracting properly due to an obstruction. Turn off the water supply to the faucet and disconnect the hose from the faucet. Carefully inspect the hose for any kinks or blockages. If you find any obstructions, gently straighten out the hose and remove the blockage.
3. Check for damage to the hose: The hose may not be retracting properly due to damage. Check the hose for any visible signs of wear and tear, such as cracks or tears. If the hose is damaged, it will need to be replaced.
4. Lubricate the hose: Over time, the hose can become dry and lose its flexibility. Apply a small amount of silicone lubricant to the hose to help it move more freely.

If it is a press and lock style, some of them can be pulled out and adjusted to make for more clearance so the locking mechanism has room to work. If it's the style that uses a pull rod from behind the spout, then the circular nut that holds the pop-up rod into the drain directly under the sink. If that's loose, then it won't allow the pop up to stay in place. Hope this helps

Usually these things seize up and destruction and replacement is the only way. If only plumbers would use a little water pump grease or copper anti-seize, this wouldn't happen. Wrap a rubber glove around the bell and put a couple of layer of duct tape on the channel lock pliers. Not the most clever of shapes are they! https://www.faucetdepot.com/prod/Grohe-20.801.000-Geneva-Lavatory-Widespread-Faucet---Chrome-(Pictured-w-Handles--Not-Included)-2962.asp ..

SEE YOUR LOCAL DEALER AND ASK THEM

I would look on u tube for a video on this . Or contact the makes on how to do this and if its possible . Some makes are factory set .

Very hard to acquire parts... just replace it as this is quicker and easier.

Step 1
Turn off the water to your faucet.
Step 2
Remove the handle to the faucet. Remove the small screw under the lever handle with an Allen wrench or Phillips head screwdriver, depending on what type of screw is present. Slide the handle back and off the faucet.
Step 3
Remove the temperature control knob, which is the round, dial-shaped fitting over the faucet cartridge. Put the manufacturer-supplied adapter on the cartridge. Line up the lever stop pin with the arrow symbol on the cartridge.
Step 4
Turn on the water and rotate the adapter to the left, or counter-clockwise, until the water temperature is at the level you want. Take note of the number to which the adapter points.
Step 5
Shut the faucet off by turning the adapter to closed and line up the limit stop dial with the number you noted previously.
Step 6
Assemble the faucet by replacing the temperature control knob and handle, then tighten the handle screw. Turn on the water and operate the faucet. If temperature is not set properly, repeat as necessary until you achieve the right setting.

There is a set screw (blue) behind a removable plug (yellow).

Order repair kit and rebuild flash assembly.

use an articulated wrench

Corrosion/hard water scale has built up between the slotted shaft and the handle .... "cementing" it in place. A faucet handle puller may help depending on your design. This video shows how for a 2 faucet sink setup...but your 1 faucet handle should be similar. The puller will ONLY work though if you can access the end of the slotted shaft to get leverage from. Can you remove an end cap from the handle to access the shaft? ... If the puller will not work .... You could try penetrating oil (if you can get the oil to the corrosion) ... or if your handle is metal, cover it with a wash cloth to prevent marring and tap with a brad hammer. Sometimes that breaks the corrosion bond. You could also try heat/cold/heat/cold by heating with a hair dryer followed by a bag of ice water and then repeat. The temperature cycling might help. In a real pinch ... but you have to VERY careful ... use a pry bar between the escutcheon plate and the handle...go slow .... use cloth protection to prevent marring ... move the pry bar around and rock it....say at 12, 3, 6, 9 o'clock positions around the handle AND .... when you are successful ... when you reinstall ... put some silicon plumbing grease on the shaft to prevent future corrosion!

I have to rotate mine by the aerator to change flow from faucet.

so that good or not?
