Troubleshooting Guide for the 8 Steps to
Successful Service
1. Understanding the Nature of the Service Call
• If the customer reports that the system is producing hard water, the
problem is either mechanical or programming in nature.
• If the customer describes salty water, noisy operation, the system
is using too much salt, or water running to the drain, the problem
is not mechanical in nature. Solutions to these non-mechanical
problems are covered in the “Troubleshooting Guide” on pages
18-19
.
Test the Cold, Hot, and Raw Water
• If both the hot and cold water test hard on arrival, the problem may
be mechanical or a capacity issue related to programming.
• If the cold water is soft and the hot water tests hard, the problem
is most likely a capacity issue related to the programming.
3. Perform a Visual Inspection and Check the Programming
• Verify that the control is properly programmed for the water
condition and the size of the equipment.
• Verify that there are no leaks in the plumbing; something as simple
as a toilet that does not shut off properly can allow many gallons to
pass through undetected, causing a loss of capacity. Any leak under
0.25 GPM will not register on the meter.
• Verify that the system is plumbed correctly.
• Document the diagnostics for future reference; many of the diag-
nostics will reset when the system is cycled.
4. Perform a Mechanical Function Test
Cycle 1
• If the brine refill rate is too slow , inspect the brine refill
screen, injector, and the brine refill flow control. In applications
where iron is present, inspect the injector screen as the
brine refill water passes through.
• If there is no water flowing, verify that the control is in the Brine
Refill position. The brine refill shut-off assembly should be depressed
and the piston rod cycle indicator should be aligned with position
number 1.
• If the piston is properly aligned and the brine refill shut-off
assembly is not depressed, the brine cam is out of synchronization
with the drive cam. Remove the drive cam and realign it with the
brine cam.
• If the control displays
Cycle 1
,
the piston rod cycle indicator is in
position 3, 4, or 5, and water is flowing from the drain, position
sensing is malfunctioning; replace the RPS motor gear drive
assembly ( item # 2 on page 22-23)
.
Cycle 3
• If the backwash rate is too slow or fast, the backwash flow control
may be the wrong size for the tank.
• If resin is in the backwash water, reduce the size of the flow control.
Resin loss may also be caused by temperature changes in the water.
The colder the water, the more the resin will expand when the
system regenerates.
