Error Code:
C573
C573: HEATUP MODE
STEAM TEMP OVERLIM
UNPLUG / REPLUG UNIT
Steam temperature exceeds 284°F
(140°C) during HEAT UP mode.
Office running back to back cycles. Check if operator is running consecutive
cycles without completing the DRY cycle.
Complete full cycle.
If the unit skips the Fill mode...
Tray rack / tray plate not installed
properly.
Inspect tray rack / tray plate for proper
installation. (The 45 degree angled end
of tray plate must be positioned upward
and to the back of the chamber)
Install tray rack / tray plate properly.
(M11) Mesh filter not in place. Verify filter is in place. Re-Install filter.
Water Level sensor malfunctioning /
dirty.
Inspect water level sensor.
(Check for residual moisture)
Clean / Dry water level sensor.
(Clean with Speed-Clean and scotch bright pad)
Verify if filling or skipping fill.
(“filling chamber” will display on display
for 30-60 seconds)
Perform: Water Level Sensor Testing
Replace water level sensor.
If the unit completes the Fill 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.
