The hose for the spray is preventing me from removing the body of the faucet to check for wear.

My first question is it a moen factory dish spray hose for that model? If not and it is a universal type it might not work at all on the moen. If it is a true replacement part then check the threads both on the faucet body and on the hose end to make sure they are not damaged or cross threaded. If the original hose was put in and cross threaded the connection on the faucet body the new hose will probably not screw on. If this is a quick disconnect model make sure that the faucet body connection is clean and place a small amount of faucet lube on the hose connection to help with installation. Sometimes what might happen when replacing a quick connect end is the old hose left bits of O-ring in the faucet connection which will not allow the new end to seat properly.

Hi, Ok I see your problem? LOL The feed lines for the faucet are too close together at the min. you must spread the lines ever so slightly not to over bend, just enough to get the head/bottom of the hose to pull up thru the top. Fun job: level 6 on a scale 1-10. Have at it !

you have an other part that went bad. Inside the faucet there ins a part called a devertot that is in the body of the faucet. This little part move the water from the main spout to the hand held sprayer.

You have to remove the handle and the spout. pop it out pop a new one in and you are good to go.

Sounds like the old style center-control delta type faucet, rubber washers describe older type but still good. The rubber seats have holes in middle, supply water to the cylinder which diverts water to the spout, and has a seal over top of ball allowing stem for handle.

Think they are talking about flex-hose type faucet accessory getting clogged, Maybe: lift the flex-hose faucet housing off the center-control faucet body? Water to it runs directly from center-control faucet and if broken seat gets in narrow line could inhibit spray.

Kitchen faucet spout too has an O-ring under where it connects to the faucet body. Unscrew large nut where meets the faucet body unit (slip-joint pliers), once free of threads, spout should pull straight up, easy or slight tug. I use bent paper clip to remove old one trying to save it in one piece so as to get exact size (that's important) to replace, push on one side then other.

there is sediment in it somewhere. flush lines out.

You need to turn the water off under the sink. Disconnect the sprayer hose from the threaded shank under the center of the faucet body. Pull the spray head out of the faucet. Contact Blanco to receive your faucet parts free.

Remove spray head then faucet tighten connection on the spray hose

your sprayer ''picks up''it's supply from the flow to your faucet.spray heads wear out & are not repairable.replacement hose & sprayer assembly can be found at home improvement stores.if you can see the other end of the hose where it attaches to the faucet,it's not too hard to replace.you don't have to turn off the water at the meter.

check the sprayer handle by disconnecting and blowing into it and pressing sprayer handle and/or for possible kink at main body or hose by disconnected sprayer point hose into sink and turn on water. If no water the the diverter in main body is not working properly and needs to be reassembled or replaced

Your problem is a simple one.

1. Turn off water to faucet.
2. Place a towel(s) in the base of the sink(s) to prevent any parts from going down drain.
   
3. Remove the handle to the faucet. (single handle only)
   
4. If not a single handle then remove spout from faucet.
5. If a single handle remove cap carefully and any loose parts.
6. Gently turn spout side to side while lifting to remove.
7. You will see a hole with a very small valve where the water comes out to the spout on the base of the faucet.

1. Remove this valve (which is a backflow preventer) and replace.
2. Reassemble and test.
   

Problem solved.
