.
C574: STERILIZE MODE
STEAM TEMP OVERLIM
ITEMS NOT STERILE
UNPLUG / REPLUG UNIT
Steam temperature exceeds 284°F
(140°C) during STERILIZE mode.
Heating element malfunctioning. Inspect heating element. Heating element
should lay flat in the bottom of the chamber.
Heating element should be free of any
flaking / pitting.
Perform: Heating Element Resistance Test
(should read 9-11 Ω)
Replace heating element.
Chamber filter clogged. Check if chamber filter is clogged. Clean / Replace filter.
(Clean with Speed-Clean and brush)
Pressure tubing at incorrect angle. Check tubing for restrictions and
ensure tubing is angled down and
away from the PC Board.
Adjust pressure tubing to correct angle.
Error Code:
C575
C575: VENT MODE
STEAM TEMP OVERLIM
ITEMS NOT STERILE
UNPLUG / REPLUG UNIT
Steam temperature exceeds 284°F
(140°C) during VENT mode.
Sterilizer is unlevel.
(remove tray / trays)
Verify support surface is level. Place sterilizer on a level support
surface.
Verify water on all sides of chamber
are equal.
Temperature sensor malfunctioning. Check for residue build up on temperature
sensor probe.
Clean sensor probe with Speed-Clean,
distilled water, and abrasive pad.
Check that nothing is touching or crowding
the temperature sensor.
(Example: trays, pouches, cassettes, etc.)
Reposition items so nothing touches or
crowds the temperature sensor.
Perform Temperature Sensor
Resistance Test. Allow sensor to cool to
room temperature before testing.
Acceptable range 1.07-1.1K Ω.
Refer to:
Temperature Sensor Resistance Test
Replace temperature sensor.
Perform Temperature Sensor Supply
Voltage Test. Disconnect sensor
harness from J12 on PC board.
On pins 1 & 2 acceptable range is
4.0 - 6.0 VDC. Refer to:
Temperature Sensor Supply Voltage Test
Replace Main PC board.
Pressure Leaks. Check for loose / worn door and dam
gaskets or water leaking around door.
Verify door and dam gaskets are installed
properly. (Replace gasket kit 1x year)
Clean / Replace gaskets.
Replacement fill / vent valve solenoid
requires rectifier harness for DC coil.
Install rectifier harness.
Check for voltage flow through rectifier
harness. Refer to:
Fill / Vent Valve Supply Voltage Test
Replace rectifier harness.
Leaking or defective vent valve.
(Check for water leaking from
condensing coil spout)
Perform: Vent Valve Test
Clean / Replace vent valve.
