Pentair FLECK 5600 User manual

A) Electrical service to unit has
been interrupted.
B) Timer is defective.
C) Power failure occurred.
A) Assure permanent electrical service
(check fuse, plug, pull chain or switch)
B) Replace timer motor.
C) Reset time of day
A) By-pass valve is open.
B) No salt in brine tank.
C) Injectors or screen plugged.
D) Insufficient water flowing into
brine tank.
E) Hot water tank hardness.
F) Leak at distributor tube.
G) Internal valve leak.
H) Reserve capacity has been
exceeded.
I) Program wheel is not rotating with
meter output.
J) Meter is not measuring flow.
A) Close by-pass valve.
B) Add salt to brine tank and maintain
salt level above water level.
C) Replace injectors and screen.
D) Check brine tank fill time and clean
brine line flow control if plugged.
E) Repeated flushings of the hot water
tank is required.
F) Make sure distributor tube is not cracked.
Check O-ring and tube pilot.
G) Replace seals and spacers and/or piston.
H) Check salt dosage requirements and reset
program wheel to provide additional reserve.
I) Pull cable out of meter cover and rotate manually.
Program wheel must move without binding and
clutch must give positive “clicks” when program
wheel strikes regeneration stop. If it does not,
replace timer valve head.
J) Check output by observing rotation of small gear
on front of timer with water running in house (Note:
program wheel must NOT be against regeneration
stop (0) for this check.) Each tooth to tooth is
approximately 30 gals. If not performing properly,
replace meter cover (dome).
A) Improper salt setting.
B) Excess water in brine tank.
A) Check salt usage and salt setting.
B) See problem #7

A) It is very common for the main and brine
pistons to need replacement after 5-10
years of use. The valve will get stuck
trying to complete a regeneration cycle.
Very often this occurs at the beginning of
the “brine rinse” cycle. The timer motor
may stop at this point also. The motors
are made to stop instead of forcing the
valve (which results in gear damage).
A) Replace the main piston and the brine piston
assembly. If the valve is on a chlorinated water
source or over 10 years old, it’s a good idea to
replace the main piston seals at the same time.
On rare occasions the timer motor may also
need to be replaced. Try the pistons replacement
first, this usually does the trick.
Piston Stuck in
Control Valve

A) There are a number of reasons why this can occur. To test if gears need replacement, remove
the meter dome, turn the cable by hand and observe the small white gears inside. You should
be able to make them turn with normal finger pressure. They should also continue to spin for
a moment after you stop applying pressure. If you cannot turn the white gear, you need to
replace the “meter cover”.
Most residential models use the standard range (0-21, i.e. 2,100 gallons) black plastic meter
cover and matching program wheel on the control. There is an extended range (0-55, i.e. 5,500
gallons) that is also available. Fleck also makes a brass 1” meter. This would only be found on
large commercial applications.

Another problem that can occur with the Fleck 5600 Econominder (metered) valve. The gears inside the meter dome cover fail.
This can be due to a number of reasons.
The way to tell if this part needs replacement is to remove the meter dome, turn the cable attached by hand and observe the
small white gears inside. You should be able to make them turn with normal finger pressure. They should also continue to spin
for a brief moment after you stop applying pressure. If you cannot turn the white gear, you need to replace the “meter cover”.
Most residential models use the standard range (0-21, i.e. 2,100 gallons) black plastic meter cover and matching program wheel
on the control. There is an extended range (0-55, i.e. 5,500 gallons) that is also available. Fleck also makes a brass 1” meter.
