    Backflush
    The detergent you add to your tank may congeal and separate from the water over time. The congealed detergent may accumulate in the tank, hose, tube and wand. Miscellaneous particles that come through your water lines may also accumulate. Backflush to wash out the obstructions. Caution: this procedure causes water to flow backward. Be sure to follow the steps to confine the water to the sink.
    • Lift the detergent tank, with lid and tube attached, into the sink.
    • Unscrew the lid from the tank and place it in the sink with the two small holes facing downward.
    • Place a sponge or dishcloth in the bottom of the sink.
    • Remove the brush from the end of the wand.
    • Turn on the water and adjust the temperature to warm.
    • Divert the water from the spout to the wand.
    • Press the end of the wand into the sponge or dishcloth to restrict the water flow - you will not be able to completely restrict the flow.
    • Press the red button.
    • Water should flow from both small holes and from the end of the tube where it is attached to the button at the top of the lid.
    • Clean the detergent tank.
    • Refill the tank.
    • Reattach the lid.
    • Place the assemble detergent tank beneath the sink.
    • Reattach the brush to the wand.
    • Your Dishmaster will work best if you routinely perform this procedure. Make it a habit to take a few moments and backflush every time your tank runs empty and before refilling.
    Care and Cleaning
    Use a mild cleanser such as liquid dishwashing detergent to clean your faucet. Always test a cleaning solution in an inconspicuous area before cleaning the entire surface. Do not let the cleanser sit on the surface for any extended period of time. Immediately rinse surfaces with clean water. Use a soft, dampened sponge or cloth, never a scouring pad, brush or other abrasive material.
    Brushes will give many months of service with proper care and use. To clean the brush, flatten the brush on the bottom of the sink to spread the bristles, press the red button and run hot sudsy water through it. If the brush becomes grease coated, use a little grease-removal type cleanser. Replacement brushes are available for a variety of applications.
    Aerator
    If the water stream from the spout is weak or uneven, the aerator may have accumulated particulate (tiny bits and pieces of things that come through your water lines). Follow this procedure to remove the particulate. Plug or cover your sink drain(s) so that no small parts will go down the drain if you drop them. If you must use pliers to remove the aerator, pad the jaws with a cloth to prevent scratching the surfaces.
    • Unscrew the aerator assembly from the end of the spout by turning it counter-clockwise.
    • Be certain to capture the black gasket. It will sometimes stick to the end of the spout rather than come off with the aerator assembly.
    • There is no need to disassemble the aerator components.
    • Turn the aerator assembly upside down and tap it on the countertop until the accumulation of particulate is removed. It may help to rinse the aerator assembly.
    • Use white vinegar or a commercially available product to remove lime or other mineral deposits.
    • Run water through the spout to wash out any particulate that may be in the spout.
    • Place the black gasket into the aerator assembly.
    • Screw the aerator assembly back onto the end of the spout. Hand-tighten only. Do not use pliers.
    Diverter
    The diverter rod is in the center of the spout below the black diverter knob. If the rod becomes dry or sticky it may not automatically drop when the water is turned off.
    • Lift the diverter knob all the way up and hold. Use a soft cloth and a mild cleanser to clean the diverter rod. Do not scratch the surface of the diverter rod.
    • Rinse and dry the rod.
    • Lift the diverter knob all the way up and hold. Apply a small amount of non-toxic plumber’s grease to the diverter rod.
    • Work the diverter rod up and down to coat the diverter rod and push the grease down into the seals located in the spout base.
    Valve
    Your Dishmaster Faucet has been tested at the factory to ensure that it works properly. However, due to differing water pressure or conditions in your home, some adjustment may be necessary to keep it working properly. If your faucet develops a leak from beneath the handle or a drip from the spout, please try the following before contacting customer service.
    Remove the red/blue plug on the lower face of the lever handle.
    Loosen the set screw located beneath the plug using the combo tool (or a 1/8” hex key) and pull straight up on the handle to remove the handle from the faucet.
    You should now see the stem of the ball valve that your handle was attached to, a plastic piece with a heart shaped hole in it called a cam, and an adjustment ring. The adjustment ring has four equally spaced notches around the face.
    Use the spanner end of the combo tool (a butter knife or similar can be substituted) to tighten the adjusting ring by putting the tabs of the tool into the notches on the adjusting ring and turning it clockwise. Tighten the ring in only very small increments of 1/4 turn or less. Slip the handle back onto the stem (it is not necessary to tighten the set screw at this time) and turn the water on and off to check that the leaking/dripping has stopped before further tightening the adjusting ring. Repeat as necessary until leaking/dripping has stopped.
    If the adjusting ring is adjusted too tightly, the lever handle will be difficult to move. If the adjusting ring is adjusted too loosely, water will leak past the valve seal and may drip from the spout.
    Once the faucet is adjusted, place the handle back on the stem, tighten the setscrew, and insert the red/blue plug.
