Instead of connecting the washer to it's water supply at a sink faucet, I want to connect it to its own water supply line while keeping the quik connect feature. see add more details

It will depend on what kind of faucet it is. You can get adapters for the faucet on your kitchen sink but I find they are not very good for pressure washers. They can leak and spray water all over your sink and kitchen. For a pressure washer it is best to have an outside faucet fitted. This will give you the correct type of faucet to connect to and a good supply of water to the pressure washer.
It is usually not very expensive to get one fitted.

First shut off water to faucet and second unless you installed it which sounds as if you did not under the sink and behind you'll see the faucet attached with a single nut that unscrews. Typically when you get a new single hole they come with their own wrench to install and remove it. You need to first see if you can get a pair of channel locks on the nut and just slightly loosen the nut. From there disconnect the supply lines loose from the copper lines coming off of the faucet. Careful; copper is soft.. Once you unscrew the supply lines, have a bowl handy to put the water into. Reach under again and hold the large nut and unscrew the entire assy from the top. I found this the easiest. gently bend the copper supply lines inward so that they will exit. To install, clean sink surface and be certain to check the washers inside the supply lines. If they are old, you should install new ones to prevent future leaks. Tighten the new faucet with the new wrench and keep it under the sink for future and be careful tightening the new supplu lines because you van actually twist the copper from the new faucet. Snug is good. You've done it!

The dishwasher usually drains into disposal, or directly into tailpiece, and water drains down to the p-trap.
Trap may be clogged or stopped up.
Clean out drain line, tighten connection where dishwasher attaches.
Clean out bottom of disposal under cutter blade.

Hi... I had the same problem. Instead of trying to figure out the faucet/adapter issue (was too pissed off) :) I took my old washer hose and just used that. Connect the washer hose to your sink and the washer just like it would be if you used that adapter hose. You will want to make sure it is tighten good or it will leak a little...and make sure that the adapter hose end is in your sink because that is where the used water empties out from.
Hope this helps.

What is likely happening is a small piece of sediment has become lodged in either the mixing valve or in the aerator.

Begin with the easiest part first. The aerator is the threaded attachment from which the water comes out of the faucet. Remove the aerator from the faucet and run the tap without it installed. If the flow rate is good either clean or replace the aerator.

If this was not the problem then the solution becomes much trickier because the obstruction is likely in one of the lines coming into the faucet or in the body of the faucet called the mixing valve. This is where the hot and cold water mix inside the faucet.

Our next step is to create negative pressure inside the faucet in an attempt to remove the buildup restricting the flow.

If you don't have shut off valves under the sink you will need to shut off the water supply to the home, remove the faucet from the vanity/sink and perform the following procedure.

Shut the hot and cold water off underneath the sink and remove the supply lines at the shut off valves but leave them connected to the faucet. You will need to purchase two adapters for the aerator that will allow you to connect a garden hose from your closest water supply (kitchen sink) to the vanity faucet. You can find these at your local hardware store. You will also need a pail under the vanity to catch the water coming out of the vanity faucet supply lines. Connect the garden hose from an active water supply to the vanity faucet. With someones help have them turn the water supply on which will then run backwards through the vanity faucet and into the pail underneath the vanity. Be sure to open the vanity faucet taps to full so that water will run through the faucet. This should dislodge the obstruction.

Turn off your water supply to the sink the disconnect the supply lines to the faucet. Reconnect supply lines making sure to use plumbers pipe joint compound of teflon tape. I've found teflon tape to be better. When installing the supply lines make sure that the threads aren't crossed and the retaining nut is snug.

There are 2 sets of nuts and washers underneath the faucet that holds the faucet in place. loosen them and the water lines (after turning the water off) faucet lifts off from the top of the sink. Replacement the the same, just in reverse. BE SURE TO USE TEFLON TAPE OR PLUMBERS PUTTY ON THE WATER LINE THREADS TO PREVENT COSTLY LEAKS.

Hi...
Did you check at the point where hose is connected to the faucet? Have you actually taken the hose where you connected it to the new valve and first ran it unconnected into a sink or a bucket to make sure you have a good, strong flow of cold water? A new valve isn't going to solve the problem if the supplied water pressure is low. Around here I have seen water softeners fail and allow a sludge of crystals and "goo" to clog the screens in the feed hoses on the supply side.

Fist and foremost, make sure that you have a good supply of cold water coming out of that hose. Don't make the mistake a lot of my customers make- They think if they turn on the faucet to the sink next to the washer and there's strong flow, this means everything is ok. The faucet has no screens in it. The hose to the washer does. There are screens of course at the water valve on the washer, but there are also screens in the hoses at the faucet where the washer hoses attach. Check there.

Hope this helps....

The screens in the line are clogged. There is usually a screen in the washer hose at the point where it is connected to the faucet as well as one by the water inlet valve. NEVER REMOVE THE SCREEN BY THE WATER VALVE. As for the one in the cold water fill hose, that can be cleaned or replaced.
