    M76XL Imperial Four XL - Maintenance

    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 into the detergent tank. The tank could overflow.
    • 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 into the tank.
    • Cover the stand tube in the detergent tank with your thumb or finger to flush the small hole at the base of the tube.
    • If necessary, the water pathway from the small hole to the tubing connection may be cleared with a straightened paperclip (or similar) bent to 90° at approx 3/4" - insert the 3/4" end into the small hole up to the 90° bend.
    • Clean the detergent tank.
    • Refill the tank.
    • 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.


    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.
    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.
    Over time, the bibb washers will wear and a drip may develop at the end of the spout. This quick procedure will stop the drip and extend the life of the washers. Check the temperature of the water that is dripping from the spout to determine whether it is the hot or cold handle that needs adjusted.
    These instructions are for the hot side. Cold side instructions are in parenthesis ( )
    • Turn the handle clockwise to the closed position (counter-clockwise for cold)
    • Remove the screw from the faucet handle
    • Remove the handle from the faucet by pulling straight off
    • Do NOT turn the handle when pulling it off
    • Rotate the handle counter-clockwise one notch (clockwise for cold) - One notch only, do NOT over tighten
    • Reinstall the handle by pushing straight onto the stem to fully engage the knurls
    • Turn the handle clockwise to the closed position (counter-clockwise for cold)
    • Reinstall the screw
    If the drip has slowed but not stopped, repeat the procedure or check to see if it is the other side that is causing the drip. Follow this procedure anytime in the future that a drip from the spout develops. Being careful to NOT over tighten the stems will greatly extend the life of the washers. Eventually, usually years, depending on your water condition and amount of use, the bibb washers or the torque-free valve stem ends with washers will need to be replaced.
