8.0 – TROUBLESHOOTING TIPS
CONDITION:
WATER QUALITY SENSOR TROUBLESHOOTING
Applies to the STATIM models with water quality sensor
only.
THINGS TO CHECK
Troubleshooting Procedure:
STEP #1 
 - Verify that the main PC board is operational.
Measure the voltage between P1-1 and P1-3. The reading
must be between – 8.4 and – 9.7 VDC. If not, the main 
PC board is bad, see pages 46 and 47, Figure 9.8 - 
Electrical Diagram.
STEP #2 - Remove power from autoclave, disconnect the
water quality sensor from J4-3 and J4-4. Restore power
and begin an “unwrapped” cycle. If cycle starts with sen-
sor disconnected, then the main PC board is bad. If “RE-
FILL RESERVOIR EMPTY WASTE BOTTLE” error appears
on LCD proceed to the next step.
STEP #3 - Short probe terminals J4-3 and J4-4 together
and start a cycle. If “WATER QUALITY NOT ACCEPTABLE”
displays on LCD proceed to Step #4; if not the main PC
board is bad.
STEP #4 - Remove the short from J4-3 and J4-4. Short
the float terminals together on the main PC board (J4-5 &
J4-6). If the cycle starts, the main PC board is good and the
water quality sensor is bad. If the LCD reads “WATER
QUALITY NOT ACCEPTABLE”, the main PC board is bad.
STEP #5 - To verify the water quality sensor, short the two
pins coming from the front of the sensor together. The sen-
sor should read less than 1 Ω.
Upon verification or replacement of water quality sensor,
test the reservoir’s water quality using the Water Quality
Tester (RPI Part #RPT820). See page 14, Figure 2.11 -
Water Quality Tester.
CONDITION:
WILL NOT POWER UP
THINGS TO CHECK
• Check po
wer source to power cord, AC receptacle to
power switch, and wiring to the main PCB.
• Check 15 amp ceramic fuse.
• Inspect, clean and adjust contacts of fuse holder if nec-
essary.
• Main PC board is bad and must be replaced.
For all of the above see pages 46 and 47, Figure 9.8 -
Electrical Diagram.
CONDITION:
WILL NOT PRINT
After an error fault occurs, the error must be c
leared be-
fore shutting down by pressing the Stop button.
THINGS TO CHECK
• If the time and da
te are not displayed on the printer's
LCD, check power cable connections.
• Check the loading of printer paper, paper must roll out
from the top. Verify that the paper is not jammed.
• Replace printer if necessary.
CONDITION:
LEAKING STEAM:
PRV (PRESSURE RELIEF VALVE)
(Also kno
wn as Safety Valve)
THINGS TO CHECK
• Check cassette seal port holes and steam ports on probe
bracket (look for obstruction).
 Clean and lubricate the
cassette seal – see page 10, Figure 2.7 - Liquid Soap
(RPI Part #RPS287). Replace the Cassette Seal (RPI Part
#SCS001 fits model 2000) or (RPI Part #SCS029 fits
model 5000) if necessary.
• Check the plumbing from the steam generator/boiler to
the probe bracket fittings (look for obstruction). See
page 38, Figure 9.1 - Steam Generator/Boiler.
• If the problem repeats, replace the Safety Valve (70 psi)
(RPI Part #SCV004).
8.0 – TROUBLESHOOTING TIPS
(continued)
CONDITION:
WRAPS/INSTRUMENTS REMAIN WET AFTER DRYING
THINGS TO CHECK
• Check air filters,
 and replace if necessary (RPI Part
#SCF002, SCF031 and SCF032).
• Check leveling of the STATIM – Note the position of the
bubble in the Bull’s-Eye Level (RPI Part #SCL012) that is
located on the top right of the autoclave. A properly lev-
eled autoclave would show the bubble in the 4 to 5
o’clock position. If leveling is improper, adjust the feet
until proper level is achieved. 
• Water level in the waste bottle may be full, or the ex-
haust path may have a restriction or blockage.
• Check exhaust tubing for kinks or pinch points. Note: RPI
offers an Exhaust Tubing Kit (RPI Part #SCK017) or Ex-
haust Tubing sold by the foot (RPI Part #RPT380).
• Check the cassette tray venturi plate for blockage - see
page 42, Figure 9.5 - Cassette.
• Check air compressor for proper operation - see pages
44 and 45, Figure 9.7 - Air Compressor.
• Check solenoid valve for proper operation - see page
41, Figure 9.4 - Solenoid Valve.
CONDITION:
IF "CLICKING NOISES" ARE HEARD
Sounds like the solenoid valve is being activated without
the cassette inserted or at improper times during a cyc
le.
THINGS TO CHECK
• The microswitch may have failed. One cause for this fail-
ure could be a cassette steam leak. Repair leak and
retest. If condition persists, replace the Microswitch Kit
(RPI Part #SCK007). See page 9, 2.5 -  Hex Balldriver
(5/64") (RPI Part #RPT297), For Use When Replacing
the Microswitch.
NOTE: This can also happen with the cassette installed
before or just after starting a cycle. The steam works its
way past the switch’s seal into the switch causing the N.O.
contacts to short out and become closed (or possibly an in-
termittent signal). The autoclave would then proceed as if
the microswitch had been activated.
CONDITION:
IF "BUZZING NOISES" ARE HEARD
Sounds like the solenoid valve is buzzing with the cassette
inserted or at improper times during a cyc
le.
THINGS TO CHECK
• Solenoid valve plunger may be compromised by debris
or may be worn. Check operation of plunger inside the
flute/bonnet for proper movement. Replace Solenoid-
Plunger Kit (RPI Part #SCK003) if necessary. See page
41, Figure 9.4 - Solenoid Valve.
CONDITION:
IF "RATTLING NOISES" CAN BE HEARD
Sounds coming from air compressor during the dr
ying
cycl
e or at improper times during a cycle.
THINGS TO CHECK
• Check the air compressor filter. If stains or moisture are
present, replace the Air Compressor Filter (RPI Part
#SCF002) and the Check Valve (RPI Part #SCK011).
Note: Once the air compressor filter shows signs of mois-
ture, the check valve has failed and must be replaced.
Damage will occur with the air compressor if unattended.
This can lead to a costly repair.
CONDITION:
IF MAJOR COMPONENT CONTINUOUSLY RUNS
Air compressor
, solenoid valve, pump or steam genera-
tor/boiler activates and does not turn off at it's a
ppropri-
ate time.
THINGS TO CHECK
• Main PCB board is bad and must be replaced.
