C571: SELECT MODE
STEAM TEMP OVERLIM
UNPLUG / REPLUG UNIT
Steam temperature exceeds 284°F
(140°C) during SELECT mode.
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.
