Things To Know
For sink or countertop installation the M76 requires 2 holes (minimum 7/8” diameter) on 8” centers and fits all standard 3-hole and 4-hole sinks. For wall or ledgeback installation the M76 requires 1/2" MIP water pipes on 8” centers. The mounting hardware allows for both vertical and horizontal adjustment.
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/countertop installation.
Your Dishmaster is designed to use liquid detergents. Do not attempt to use soaps or soap powders. We recommend Dishmaster® Liquid Detergent Concentrate. Other name brand liquid detergents may work in your Dishmaster. Do not use detergents with lotion additives. Avoid detergents that appear opaque or cloudy rather than transparent.
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.
OperationAttach the Brush
- Engage two lugs on the inside of the brush in the brush adapter slots and rotate 1/4 turn clockwise.
- 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.
- Remove the detergent tank lid.
- Fill the tank with warm water.
- Add one tablespoon liquid detergent concentrate to the tank.
- Gently stir to thoroughly mix the detergent into the water.
- Replace the lid.
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 or if you use a detergent with a lotion additive. Perform the quick back flush routine each time before refilling the tank to keep your Dishmaster in top working condition.Use the Wand
- Turn on the water and adjust the volume and temperature as desired.
- Lift the wand and grip it by the handle.
- Point the brush downward into the sink basin.
- Lift the diverter knob.
- 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.
- Turn off the water.
- 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 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.
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. Back flush 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 firmly into the sponge or dishcloth to restrict the water flow as much as possible. 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 back flush every time your tank runs empty and before refilling.Aerator
If the water stream from the spout is weak or uneven, the aerator may have an accumulation of particulate that has 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.
- Soak the aerator in white vinegar 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 located in the center of the spout below the black diverter knob. If the rod becomes dry (lack of lubricant) or sticky (something has splashed onto it) it may not automatically drop when the water is turned off.
- Lift the diverter knob all the way up and hold. Use a soft, damp cloth to clean the diverter rod. Do not scratch the surface of the diverter rod. Use a soft, dry cloth to dry the rod.
- Lift the diverter knob all the way up and hold. Apply a small amount of non-toxic silicone plumber's grease to the diverter rod. WD-40, detergent, Vaseline, cooking oil, etc are NOT acceptable substitutes. Work the diverter rod up and down to coat the diverter rod and push the grease down into the seals located within the spout.
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 ( )
- Rotate 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 rotate the handle while pulling it off.
- Once removed, 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.
- Rotate 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 conditions and amount of use, the bibb washers or the torque-free valve stem ends with washers will need to be replaced.
