SERVICE CODE FLOW CHARTS
Check incoming Power.
-If the voltage is below 108 VAC when wired for 115 or below 216 VAC when
wired for 230, the voltage is too low for proper operation.
-If the voltage is good, replace the transformer.
No
Code combination of
170 & 187
?
Replace
PIB.
Yes
Conduct a transformer voltage test on the PIB.
Are the readings correct.
Yes
No
Yes
Code
170
Does the 170 appear
upon power up to the
AquaPure without
waiting for the 5
minute wait period?
Turn Power off, remove the
Sensor from the PIB, and
Power Up the AquaPure.
Does the 170 appear upon
power up without waiting the
5 minute wait period?
Perform transformer
voltage test and sensor
reading test. Replace
the PIB or Transformer
as needed.
Inspect Sensor and
replace.
No
Code combination of
170 & 191
?
Yes
No
Visually check the DC cell cord
and outside of cell. Are they
connected loosely together or are
there signs of damage?
Loose connection = Reconnect
firmly.
Damaged cell or cord = Replace
cell and cord.
Next, Restart the unit and wait for
system diagnostics.
(Approximately 5
minutes).
Reinstall and restart the unit. Wait for
system diagnostics.
(Approximately 5 minutes).
Does the system show the same
service code?
Remove Cell and
visually check calcium
build up and or debris. Is
the cell clean?
Clean the cell with 4 parts water and 1
part muriatic acid. Rinse with fresh
water when done.
No Code = System
Operating Normally
Different Code = Proceed to
that code.
Yes
Yes
No
No
No
Yes
Replace the PIB.
Code combination of
170 & 193
?
PIB measured significant
current when the unit is
either resting or off. Replace
PIB.
Test cell voltage at the cord
connection on the PIB. Is the
voltage less then 19 VDC?
Are there 160 DC
Millivolts or higher at the
cell current test points?
No
Yes
Restart the unit and wait for
system diagnostics.
Check for Metals in the water and
possible shorts between the plates
& posts on the cell and inside the
cord.
Code combination of
170 & 195
?
Conduct a sensor
reading test. Does it
pass the test?
Replace the flow sensor.
Replace the PIB.
Yes
No
