Check
Cassette
#6
The steam generator temperature is more
than 5°C higher than the chamber
temperature.
Most probable causes are a blocked duct, a blocked solenoid valve, miscalibration or a pinched
exhaust tube.
Check
Cassette
#7
The cassette temperature has dropped
below 130.5°C during the sterilizing phase
of the UNWRAPPED or WRAPPED Cycle,
or below 117.5°C during the sterilizing
phase of the RUBBER & PLASTIC
Cycle.
Most probable cause is a faulty solenoid valve.
Check
Cassette
#8
The chamber temperature is more than 5°C
higher than the steam generator
temperature.
Most probable causes are thermocouple miscalibration or very strong pump delivery.
Check
Cassette
#9
This is a special error message for the U.K.
market. The chamber temperature has
exceeded 139°C during the UNWRAPPED/
WRAPPED Cycle, or has exceeded 126°C
during the RUBBER & PLASTIC Cycle.
Most probable causes are a blocked or faulty solenoid valve or a pinched exhaust tube.
Service
Needed
The steam generator temperature has
exceeded 170°C, chamber temperature has
exceeded 147°C, or the thermocouple is
faulty.
Most probable causes are a blocked or faulty solenoid valve, a pinched exhaust tube, a broken
thermocouple lead, an open, disconnected or defective thermocouple, a weak pump or a
contaminated steam generator.
Check
Cassette
(without a
number)
The cassette temperature has failed to drop
to 103°C within a timeout period at the end
of a cycle.
Most probable causes are a blocked exhaust duct in the cassette, a blocked or faulty solenoid
valve or a pinched / kinked exhaust tube.

Description of Error Message
Probable Cause of Error Message
Check
Cassette
#1
The cassette temperature failed to reach
95°C in 3 minutes.
This error message occurs only during warm up. The most probable causes are:
1. Steam generator does not heat up. No power to steam generator. Blown thermal fuse.
2. Check for a large cassette leak or a large load.
Check
Cassette
#2
The cassette temperature failed to increase
from 95°C to 100°C within 1 minute 20
seconds.
Most probable causes are a faulty cassette seal, miscalibration, a damaged cassette, improperly
adjusted or failed microswitch allowing unit to function when cassette is not fully inserted.
Occasionally, a low pressure weather system in higher altitude sites will alter the boiling
temperature significantly and trigger this fault.
Verify Vref to be 4.0V.
Check
Cassette
#3
The cassette has failed to pressurize and
achieve a temperature of 110°C within 70
seconds of pressurization.
This may be caused by a faulty or worn cassette seal, a faulty or dirty solenoid valve, a damaged
cassette or a faulty exhaust tube, leaky check valve or pressure relief valve.
Check
Cassette
#4
The cassette has failed to achieve
sterilization conditions within 10 minutes of
the chamber first reaching
102°C.
Several conditions may cause this: a damaged or worn cassette seal, a faulty solenoid valve,
improperly installed copper tubing, cassette thermocouple misalignment or damage, a faulty
steam generator pressure relief valve or a faulty check valve on.
Check
Cassette
#5
The software causes the pump to activate
while between 2 minutes 44 seconds and 2
minutes 24 seconds remaining in the cycle.
If a request to pump water occurs outside of
2 minutes 44 seconds, Check Cassette #5
occurs.
This indicates a substantial steam leak from the cassette, a contaminated steam generator or a
weak pump.
