Franke Kitchen Spray Head Part # 4089. Lever on top moves it from stream to spray While on Stream Spray is leaking.... Tried changing washers 1st...then tried new aerotors... still leaking

Turn counterclockwise

Replace that washer and tighten well.

Question...we are not having any leaking, but it's stuck in sprayer mode! When turning the head, it will have a slight single stream from the middle , biut the spray continues as well. We've cleaned it & spun the head every which way. Any ideas?

There are websites that give instructions for disassembling the Franke faucets. Also, some have a valve cartridge ($20-50) that can be replaced (you take the handle off, the catridge is inside)/

take old sprayer with you and you should be able to get one at a hardware or even at homedepot.most sprayers come apart. maybe the rubber ring is bad on inside of sprayer.

Take the head apart and clean it and it should start working again.

Where you able to figure this out? I am having the same issue with my Pegasus K300.

there is sediment in it somewhere. flush lines out.

Having installed and fixed kwc domo faucets for years I'd probably take the spray head off of the hose, then look into the bottom of the spray head and see if the check valve is still there. It probably is. I used to use a thin screwdriver to pry the check valve out out.It will come out. You need to work at it a bit but these hold back a lot of water pressure and catch any crud coming down the water lines.

No a pull out sprayer problem is different.

First try this. Pull out the sprayer and remove from hose by turning nut that connects sprayer to hose. If you can get someone to help you it would be nice since the hose can go down into the faucet and might be trouble to retrieve. Look in the connection on the sprayer where the hose connects and look at the screen. If the screen is plugged or dirty clean and reinsert. If you can't clean it replace it. If this isn't working go to the next suggestion below.

In the spray head of the faucet there is a build up of deposits from use and or water hardness. Here is the link to the Delta site.

Delta Faucets

If you find you faucet model order a new spray head. Once these go bad they usually need replacing.
