2008T Troubleshooting Guide
P/N 490292 Rev. A
I) If Flow Error EVER = 1, even just once, a masked Flow
Error is occurring! WITHOUT LOOKING AWAY watch it for
three (3) minutes or until it EVER = 1. TWO (2) possible
scenarios:
1) IF Flow Error EVER = 1, even just once! DO NOT troubleshoot overflow instead troubleshoot the
flow error! Refer to the Table of Contents for whatever program the machine is in.
2) IF Flow Error ALWAYS = 0! Is the machine in: i) A Cleaning Program OR ii ) Dialysis Program:
i) IF in a Cleaning Program: Proceed to page 587, procedure number OVER- 2.0.0.
ii) IF in Dialysis Program: Perform parts a AND b below:
a) From the Home screen, allow [Conductivity] to increase to more than 12.0 mS.
b) Call debug screen 1. Is FILACT REMAINING ALWAYS = 1 (Yes or No)?
Yes FILACT REMAINING = 1! Proceed to page 452,
SECTION 8 – FILLING PROGRAM PROBLEMS
No FILACT = 0! See procedure number OVER- 1.0.0 (page Error! Bookmark not
defined.).
OVER- 1.0.0 ISOLATE CENTRAL (SDS) CONCENTRATE DELIVERY SYSTEM
a) Turn the machine OFF!
b) When the machine is off OR if [Dialysate Flow] is “OFF” and the machine is attached to a Central
Concentrate Delivery System (SDS), over time, SDS pressure too high may force the concentrate pumps
open causing overflow.
c) Is the red AND / OR blue concentrate connectors currently attached to a SDS system?
Yes Attached to a central system! Allowing up to ½ hour, if (and ONLY if) overflow still occurs see
procedure number OVER- 1.0.1 (page 586). If overflow is NOT occurring maybe the problem
was occurring when attached to a particular station in the clinic where the pressure is too high.
No NOT attached to a central system. If (and ONLY if) overflow is still occurring see procedure
number OVER- 2.0.0 (page 587). If overflow is NOT occurring maybe it was occurring ONLY when
attached to a SDS where the pressure is too hig.
OVER- 1.0.1 ATTACHED TO A CENTRAL SYSTEM / ISOLATE HIGH PRESSURE (Slow Overflow)
a) Disconnect the red AND blue concentrate connector(s) from the central supply.
b) Allowing one (1) minute does vent tubing overflow stop?
Yes Overflow stops! Acid and/or bicarbonate central pressure is too high!
No Overflow does NOT stop! See procedure number OVER- 2.0.0 (page 587).
