    M70 Sapphire - 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. 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 assembled 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.
    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 rotating 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.
