Kohler Co.
Recommended Action
B. If poor flush occurred soon after the toilet
was previously used, the tank may not
have refilled completely. Check the
position of the water supply shut-off
valve. If required, fully open the valve or
wait longer between flushes.
C. Check for clogged trapway or rim holes.
Clean if necessary.
D. Check for clogged soil pipe or vents. Clean
if necessary.
E. If poor flushes occur with full tanks and
clean trapway, rim holes, soil pipes, and
vents, then the pump may be the problem.
Check that the pump hoses are
undamaged and are properly installed.
F. Power interruptions or extreme low
voltage conditions can prevent pump
operations. Check that the proper electrical
power is applied to the pump.
G. If the problem persists, replace the pump.
A. Remove dirt or obstructions from the
valve head. Flush the lines.
B. The valve inlet or supply line may be
plugged. Clear particles from valve seat.
C. The supply stop may be closed. Fully open
the supply stop valve.
D. The fill valve may be clogged. Unclog the
fill valve. If the fill valve was clogged,
install a filter in the supply line to prevent
recurring problems.
E. The float valve seal may be cracked or
split. Replace the valve assembly.
A. Clean the fill valve seat/seat washer. If no
debris is found, replace the piston/seat
washer assembly.
B. Replace the fill valve if the valve float
sinks.
C. The float operates the fill valve at too high
a level. Adjust the tank water level if it is
too high.
D. Clean the valve inlet, valve head, or
supply line. Flush the lines.
