The cassette temperature rose above the high
threshold during the sterilization phase of a
cycle or above 138.6°C during conditioning or
pressurizing phase of the cycle
• Blocked cassette exhaust duct • Obstructed exhaust tubing (kink) • Sticking solenoid valve (closed)
• Failed solenoid coil
16
The steam generator temperature went above a
threshold value. (overheat)
• Blocked pump filters
• Weak pump
• Blocked or kinked pump tube
• Failed pump • Failed pump triac • Failed steam generator triac • Sticking solenoid valve (closed)
• Failed solenoid coil
• Faulty seal installation

For software rev. R1xx, R2xx and R4xx the steam generator calibration is invalid.
For software rev. R5xx and R6xx the validation thermocouple calibration is invalid.
• This occurs when a new controller board
or microprocessor has been installed. This may also happen when the unit has
been subjected to a strong static
discharge corrupting the memory.
• In both cases a new steam generator or
validation thermocouple calibration is
required.

The pump has failed to pump water into the
steam generator during a pre-vent pump time-
out. The steam generator temperature was greater than 140°C for 3.6 seconds after the
pump was activated to pump water to cool the
steam generator.
• Blocked pump filters
• Weak pump
• Blocked or kinked pump tube
• Failed pump • Failed pump triac • Failed steam generator triac • Sticking solenoid valve (closed)
• Failed solenoid coil • Faulty seal installation
• Failed water sensor (level)
