Things To Know

The M70 Sapphire is designed for sink or countertop installation on surfaces up to 1-3/4" thick and fits all standard 2, 3 and 4-hole sinks. Only two holes on minimum 4” centers are required. Please refer to the example installations.

We strongly recommend that you have hot and cold shut-off valves located under the sink and we believe flexible supply lines are the most convenient way to connect your water supply for a sink or countertop installation.

Your Dishmaster is designed to use liquid detergent. Do not use soaps or soap powders. Do not use detergents with citrus additives. Do not use detergents with lotion additives. Avoid detergents that appear opaque or cloudy rather than transparent. For more details go to:


The Diverter must be closed manually if water pressure is low or if adverse water conditions exist: well, cistern, spring, sediment, lime, iron, etc.

If you have chosen an Arced Spout: water flow may not immediately stop after the lever handle is closed.  This is a normal characteristic of any arced spout.  After the valve is closed there is still residual water past the arc of the spout and gravity will pull this water from the spout. If your water pressure is high enough it may (immediately or over time) force the air from the peak of the spout and create a vacuum. If so, the water flow will stop immediately when the lever handle is closed. You may be able to force the air out without waiting:


Every faucet’s longevity is subject to the condition of the water that flows through it. A Dishmaster is no exception. Water quality causes the most variation in the performance of a Dishmaster Faucet and water conditions vary greatly throughout the country. In addition, the unique design of your Dishmaster that allows it to dispense suds at the touch of a button means it has more components than the typical faucet. We have no control over the condition of your water and therefore do not warranty seals or rubber components. However, with proper care, your Dishmaster will give you many years of reliable service. Please take a few minutes to read through the Operation and Maintenance sections and become familiar with the use and care of your Dishmaster.

We are continuously improving the design and material content of the parts used in our Dishmaster faucets. After development and testing, we incorporate these improvements into production. Any part improved in this manner is interchangeable with the part(s) it replaces. When new style parts are supplied on a parts order they are interchangeable with the old parts.


Adjust the aerator
  • Place your fingertip on the face of the aerator and swivel it up to 10 degrees in any direction.
Attach the Brush
  • Engage two lugs on the inside of the brush in the brush adapter slots and rotate 1/4 turn clockwise.
Remove the Brush
  • Rotate the brush 1/4 turn counter-clockwise and pull off. If you continue to rotate past 1/4 turn, the brush adapter will unscrew from the end of the wand.
Fill the Detergent Tank
  • Lift the detergent tank, with hose and lid, into the sink.
  • Unscrew the tank from the lid, empty the remaining detergent solution, rinse the tank.
  • Fill the tank with warm water, add three tablespoons liquid detergent, gently stir to thoroughly mix the detergent into the water.
  • Replace the tank onto the lid.
  • Return the tank to its place beneath the sink.
Refill the Detergent Tank

Before you refill the tank is a perfect time to back flush. Over time, detergent can congeal in the components and deteriorate the performance of your Dishmaster. This is especially likely if your detergent to water ratio is mixed stronger than recommended, you use a detergent with a lotion additive, or you use soap rather than detergent. Perform the quick back flush routine each time before refilling the tank to keep your Dishmaster in top working condition.

Use the Wand

  • Open the mixer (main) valve to full flow.
  • Lift the wand and grip it by the handle.
  • Point the brush downward into the sink basin.
  • Rotate the diverter knob a full 120 degrees (1/3rd rotation) in either direction until it presses against the stop.
  • Hold the knob against the stop for a moment to allow the pressure within the cartridge to adjust.
  • Release the knob.
  • Adjust the mixer (main) valve to the desired temperature and flow.
  • Direct the spray onto the dish and press the red button for suds.
  • Sweep the brush bristles over the dish to scrub the dish clean.
  • Press the brush into the dish to spread the bristles and engage the built-in scraper.
  • Release the red button for clear water rinse.
  • When finished, close the mixer (main) valve quickly rather than slowly.
  • Place the wand in the holder.

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 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.


Back flush

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. Sediment and particles that come through the water lines may also accumulate. Back flush 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.

tank assembly
  • Lift the detergent tank, with lid and tube attached, into the sink.
  • Unscrew the tank from the lid and place the lid in the sink with the two small holes facing upward.
  • 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 bottom of the sink 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.
  • Screw the tank to 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 back flush every time your tank runs empty and before refilling.


If the water stream from the spout is weak or uneven, the aerator may have accumulated sediment and particles comes through the water lines. Follow this procedure to remove the sediment and particles. 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 sediment and particles is removed. It may help to rinse the aerator assembly.
  • Soak the aerator in white vinegar to remove lime or other mineral deposits.
  • Run water through the spout to wash out any sediment and particles 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.
