Maintaining your Dishmaster® M76

Dishmaster® Faucets are tested at the factory to ensure they work properly. However, due to differing water pressure or conditions in your home, some adjustment may be necessary to keep them working properly.

Adjust Handles

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 ( ).

  1. Turn the handle clockwise to the closed position. (counter-clockwise for cold side)
  2. Remove the screw from the faucet handle.
  3. Remove the handle from the faucet.
  4. Rotate the handle counter-clockwise one notch. (clockwise for cold side)
  5. Reinstall the handle by fully engaging the knurls.
  6. Turn the handle clockwise to the closed position. (counter-clockwise for cold side)
  7. 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.

Replace Handles

These instructions are for the hot side. Cold side instructions are in parenthesis ( ).
  1. Turn the water off at the supply valve.
  2. Turn the handle counter-clockwise to open the valve. (clockwise for cold side)
  3. Use a Philips screwdriver to remove the screw from the faucet handle.
  4. Remove the handle from the faucet.
  5. Slightly engage the knurl on the handle with the knurl on the valve stem and turn clockwise until the valve is just snug. (counter-clockwise for cold side)
  6. Remove the handle.
  7. Position the handle in front of the stem at the 7 o’clock position. (5 o’clock for cold side)
  8. Reinstall the handle by fully engaging the knurls.
  9. Reinstall the screw.
  10. Turn the handle fully clockwise to close the faucet valve. (counter-clockwise for cold side).
  11. Turn the water on at the supply valve.
If the spout drips, follow the “Adjust Handles” procedure.

Diverter rod

The Diverter Rod is in the center of the spout, below the black knob. If this rod should become dry and sticky resulting in it not dropping automatically when the water is turned off, lubricate it with a food grade non-toxic lubricant such as cooking oil or a small amount of detergent. Lift the knob, apply lubricant to the diverter rod, release the knob. Repeat as necessary until the knob raises and lowers easily without sticking.

If the diverter rod will not stay in the up position when you lift and release the knob, it may be due to high water pressure. Remove the aerator from the spout - see “Aerator”. Operate the faucet and retry the diverter. Does the diverter stay up? If so examine the aerator per the “Aerator” section and clean the aerator as needed. Deposits and particles obstructing the water flow will cause an increase in backpressure. If the aerator is clear, the diverter may not stay up due to high water pressure in the system. Reinstall the aerator and turn on the faucet. Lift the diverter knob and hold it for a moment to allow the pressure to bleed out of the spout. Release the diverter knob. The diverter should remain in the up position.

Aerator

Unscrew the aerator assembly from the end of the faucet spout by turning left (counter-clockwise). From your viewpoint above the spout, this may appear to be clockwise. Remember: lefty-loosey, righty-tighty. Be certain to remove the black seal along with the aerator. It will sometimes stick to the spout rather than come off with the aerator. If the aerator has become encrusted with lime or other deposits, it may be necessary to use pliers to remove the aerator. If so, protect the aerator’s finish by placing a soft towel between the pliers and the aerator.
Once the aerator has been removed, turn on the water. If the water flow is restored, the aerator must be cleaned or replaced. If the problem is not with the aerator, proceed to the “Spout Assembly” step. To clean the aerator, inspect the unit for foreign matter or mineral deposits. If necessary, a small wire or pin can be used to clear the holes. Rinse the unit to clear any loose particles. If necessary, remove the rubber washer from the back of the aerator and remove the plastic insert. To remove the insert, press gently on the face of the aerator. If particles can be seen inside the insert, blow air through the insert in the reverse direction from the water flow. Reassemble the aerator and screw the aerator back onto the spout. Tighten finger tight only; do NOT use pliers. If water flow is still insufficient, order Dishmaster® K1178 replacement aerator assembly.

Hose Assembly

The hose assembly, with proper care, will last a number of years. Keep the outside clean and back-flush as necessary.

Brushes

To remove the brush, turn the brush ¼ turn to the left and pull it off. To put the brush on, engage the two lugs on the inside of the brush into the slots in the brush adapter and turn ¼ turn to the right. Brushes will give many months of service with the proper care and use. To clean the brush, merely flatten it out against the bottom of your sink and run hot suds through it. If your brush becomes grease coated, a little bleaching type cleanser will remove the grease. Replacement brushes are offered for a variety of applications.
