Troubleshooting Guide

** It is imperative to identify your Faucet model to determine the correct replacement part number(s), as the size and/or number of the replacement part(s) will vary from Faucet model to Faucet
model. Please see your Faucet model’s replacement part list to determine the correct replacement part number(s). Contact MOEN at 1-800-Buy-MOEN or 1-800-289-6636 for further assistance.

Typical Cause(s)
Possible Solutions
Contacting MOEN
Water
Pressure
Low water flow from spout-both hot and
cold water on sink faucets
Depending on the model, this
could be caused by debris in the
cartridge, debris in the aerator, a
stuck diverter or a malfunctioning
wand.
It is recommended that the supply
lines from the shut-off valves be
first be checked to ensure the
faucet is receiving full pressure
from both hot and cold supply
lines.
Non-Pullout or Non-Pulldown Models
A. Remove the aerator and rinse off any debris.
B. If this does not resolve the issue, and if the unit also has a side spray, check the pressure from the
side spray. If the side spray has good pressure, then try activating the trigger on the side spray several
times to see if pressure returns to the spout. If it does not, then the diverter would need to be replaced.
Please remember that different models use different diverters.
C. If your model uses a hardware kit (Moen part number 100886) with a diverter, then it is recommended
that the hardware kit be replaced in addition to the diverter. To replace the hardware kit (MOEN part
number 100886), please call MOEN at 1-800-Buy-MOEN or 1-800-289-6636.
D. If this does not resolve the issue (or if your faucet does not have a side sprayer), the cartridge would
need to be replaced and the valve body would need to be flushed and cleaned.

Pullout or Pulldown Models
A. Remove the hose from the wand and inspect the screen that is in between these items. If there is
debris in the screen, rinse it off with water.
B. Then, hold the end of the hose in the sink and turn on the water. If the pressure is good from the hose,
reinstall the screen and wand. This should resolve the issue.
C. If there is still low pressure after reinstalling the wand, then the wand would need to be replaced. If
there is low water pressure from the hose, the cartridge would need to be replaced and the valve body
would need to be flushed and cleaned.
Bathroom Sink Faucets
A. Remove the aerator and rinse off any debris.
B. If this does not resolve the issue, then the cartridge (for one-handle faucets) or cartridges (for two-
handle faucets) would need to be replaced and the valve body would need to be flushed and cleaned.
Low flow from spout- only hot or cold
water experiencing low water flow from
spout
This is caused by the shut off
valves not being turned on, a lack
of pressure through one of the shut
off valves or an obstruction in one
of the supply lines feeding water to
the faucet.
A. Make sure that both shut-off valves are fully turned on.
B. Check both supply lines from the shut-off valves to the Faucet. These supply lines need to deliver full
pressure to the faucet. If the supply lines do not deliver full pressure, than the faucet will not produce full
pressure. The plumbing of the home would need to be investigated for a resolution.
C. If the issue is still not resolved, then the cartridge (for one-handle Faucets) or cartridges (for two-
handle Faucets) would need to be removed (or replaced) and the valve body would need to be flushed
and cleaned.
Low flow from side spray/water still
comes from spout with side spray
activated.
This is caused by a malfunctioning
diverter or debris within the
valve/spout.
A. Replace the diverter.
B. Make sure that the valve body is cleaned. In some models, the diverter is installed in the valve body;
on other models it is installed around the valve body under the spout. If it is one of these models, make
sure the spout is cleaned as well. If the side spray does not shut off completely, it would also need to be
replaced.
