As I lift the handle no water will come out..Have water pressure thru out the rest of the house just trouble with this one item

Tap and lines on hot side could be plugged.

Remove the starter housing from the top of the motor and see if the spring broke or back wound it's self when the rope broke. If all is well remove the rest of the rope from the spool by feeding it back thru the guide hole the handle rests on. Wind it out and find a hole drilled thru the spool and put a punch thru it to lock the spool in place against the spring pressure. Remove the old cord. If it has a steel hook glued to the anchor end you will need a real mercury part. If it has a knot. your in luck.

Take your new cord and burn one end and roll the cord to a point while it is still molten. Tie your knot and heat it till it is cooked so it won't untie itself. Feed the pointy end thru the spool and out the front of the housing. Tie a knot it it where the handle would go. Gently feed the rope on to the spool when you remove the punch.

You will have more rope than the spring could wind. so untie the end knot and feed it back to the spool and put the cord in the notch of the spool so it won't rub on the housing and wind a few more turns into the spring .

When it has enough pressure to completely wind the cord up. put the punch back in the lock hole and feed the cord out the hole thru the handle and knot it, then cook that knot as well.

These types faucets have a what is called an anti scald valve build into them, it is required by law, it is either defective or out of adjustment, contact a local hardware store for more detailed info.

TAKE OFF COVERS ON THE HINGES- U WILL FIND ONE HAS THE WATER LINE THERE IS A JOINER IN THE LINE, YOU PUSH THE 2 HOSES TOGETHER IN TO THE JOINER AND RELEASE THE PRESSURE TO TAKE THE HOSES OUT AGAIN. THERE IS ALSO A MULTIPLUG TO DICONECT THE WIREING TO THE DOOR- UNPLUG IT.
2/3 SCREW THRU THE HINGE WILL ALLOW YOU TO LIFT THE HINGE AND THEN LIFT OFF THE DOOR

tHE WATER LINE MAY COME THRU THE BOTTOM HINGE-

Check the inlet screen on the hose connection on the back of the machine. This may be clogged with debris, also make sure you hose is not crimped. You can unhook the inlet hose and put it in a bucket and turn it on to see how much water is actuall coming thru that hose. I suspect some type of blockage in the inlet.

the anti scold control, must be adjusted.You need to turn the water off for this,remove the handle,and the chrome sleeve,it is usually located just under the handle

CHECK THE SUPPLY LINES

lume build up. pull handle out and unscrew there should be filter inside take out and soak in a cup of lime away overnite rinse well and reinstall

maby look in to getting a prv for your house sounds like you have high water pressure

if the leak is behind the handle take the handle off and tightn the packing nut, do not over tighten, as far as luke warm water is this with just one facucet on, they way these tankless water heaters work they are by gpm, gallons per min, if you have more gallons of water going thru the unit then it is designed for then it won't get hot, if your water pressure is to high going thru it will push it to fast thru the unit and won't get hot, your house pressure should be no higher then 75lbs no lower then 65lbs
