3.1. Error Messages During Normal Operation

If an error message appears on the bottom line of the display while the machine is running, the
timer shown on the top line will stop counting. When the error is corrected, the timer resumes
counting down. To troubleshoot most errors, suspend the formula in progress and turn power off.
Do not terminate the formula if it is to be resumed after the error is corrected. See the reference
manual for more information.

CHECK PROBE
EXTERNAL FAULT
Explanation
The microprocessor is still receiving information that a level is
made just before or during an extract step, or immediately before
the fill for a bath step. This error is self-clearing when level is
lost.
Time to fill to level exceeded 10 minutes. Check the water
valves, strainers, supply lines, and water pressure. The machine
will continue to fill until level is reached, at which time the error
will automatically clear and normal operation will resume.
E-P Plus models only.The configured maximum time to steam
up to the desired temperature has been exceeded. Check the
steam valve, strainer, main steam header and pressure, etc.
Steaming will continue until temperature is achieved, when the
error will automatically clear and normal operation will resume.
E-P Plus models only.The configured maximum time to cool
down to the desired temperature has been exceeded. Check the
cooldown valve and strainer if equipped, cold water pressure,
and position of vernier valve on cooldown inlet. Cooldown will
continue until the desired temperature is achieved, when the
error will automatically clear.
The machine did not drain properly in the allotted drain time.
This self-correcting error will clear when the water level in the
basket is low enough to begin the next operation.
E-P Plus models only.This error message indicates that the
resistance of the temperature probe is outside the specified
range. Test the probe by disconnecting the probe leads from the
processor board and checking the resistance with an accurate
digital ohmmeter. Resistance between the two leads must be
between 2K and 35K Ohms. Resistance between each lead and
ground must be infinite.
On most machines, this error indicates that the programmed
chemical injection failed, usually because the chemical supply
system is empty. When chemicals are added and can be injected,
this error clears automatically, allowing operation to resume.
On 48040F7J/F7B models, this error indicates that the bearing
air pressure is below the minimum required to help protect the
bearing from water contamination.
