Symptoms
6. Massage mode shuts
down but water continues
to run from
showerhead(s).
7. Only cold water flows
from the outlets.
8. Fluctuating or reduced
flow rate. Valve is
functioning properly.
9. Blend temperature drift or
temperature cycling.
1043183-2-E
Probable Cause
A. Unequal flow rates between
valve outlets.
B. Fluctuation of inlet pressure.
C. Pressure difference greater than
5 psi (34.5 kPa) between the hot
and cold supply lines.
A. Hot water supply is either not
turned on or not connected to
the valve inlet.
B. Hot water inlet is blocked.
C. If none of the recommended
actions for the above issues
correct the symptom, the valve
requires servicing.
A. Inlet/outlet fittings may be
blocked.
B. Water outlet pressure is low.
C. Fluctuating flow.
D. If none of the recommended
actions for the above issues
correct the symptom, the valve
requires servicing.
A. Inlet temperature differential is
too great.
B. Hot water pressure too high.
C. Pressure difference greater than
5 psi (34.5 kPa) between the hot
and cold supply lines.
D. Flow rate too low.
E. If none of the recommended
actions for the above issues
correct the symptom, the valve
requires servicing.

Recommended Action
A. Verify the installation has one
bodyspray per valve outlet and
uses bodysprays with the same
flow rate. If needed, contact the
installer to revise the installation.
B. Install pressure regulators in the
supply lines.
C. Install pressure regulators to bring
the supplies within 5 psi (34.5 kPa)
of each other.
A. Check if the hot water supply is
turned on and connected to the
valve inlet.
B. Check the hot water inlet screen for
blockage. Clean or replace the inlet
screen. Refer to the Valve
Homeowners Guide.
C. Contact your Kohler Co. authorized
service representative.
A. Check the inlets and outlets for
blockage or debris. Clean the inlet
screens. Refer to the "Clean the
Inlet Screens" section.
B. Check that the flow rate is at or
above the minimum rate required.
Refer to "Specifications" section.
C. Verify that the dynamic inlet
pressures are within specifications.
Refer to "Specifications" section.
D. Contact your Kohler Co. authorized
service representative.
A. Lower the hot water temperature to
120°F (49°C). Maximum
temperature difference between hot
and cold should be 70°F (21°C) or
less.
B. Install pressure-reducing check
valve on the hot supply to achieve
equal or slight less pressure than
the cold supply.
C. Install pressure regulators to bring
the supplies within 5 psi (34.5 kPa)
of each other.
D. Check the inlets and outlets for
blockage or debris. Clean the inlet
screens. Refer to the "Clean the
Inlet Screens" section.
E. Contact your Kohler Co. authorized
service representative.
