TROUBLESHOOTING
ERROR CODES
To aid in troubleshooting, the PGM LED also serves as an error code indicator. In case of error, the LED flashes
on and off at ½ second on and ½ second off and then pauses for 3 seconds.
The flashing pattern continues as long as the controller is in Idle Mode. The number of times the LED flashes
between 3 second pauses indicates the number of the error.
Error Code Value Table
PGM Error
Interpretation
1
Watchdog timeout on filling to
level probe
6
When the controller is in either a Fill cycle or a
Teach Fill cycle, there is a 15 minute time limit until
the water level reaches the level probe.
6
If the fill valve is on for 15 minutes, the valve shuts
off and the Fill cycle aborts. The controller reverts
to Idle Mode.
2
Watchdog timeout on filling above
the level probe
6
When in a Fill cycle or a Teach Fill cycle, there is
a 5 minute limit for which the fill valve may be on
after the water reaches the level probe.
6
This error could occur in a Fill cycle only if an
incorrect time were stored in the EEPROM or read
from the EEPROM.
6
In Teach Mode, this could occur if the operator
walked away from the machine while it was in
Teach Mode. If this timeout occurs, the fill valve
turns off and the machine returns to Idle Mode.
3
Loss of master control relay during
machine cycle
6
This error could occur if the door was opened or
if the motor overloads opened during a Wash or
Rinse cycle.
4
Loss of water level during a ma
-
chine cycle
6
This could occur in two situations:
6
a) If the water in the machine drops during a
cycle because a large container being washed is
collecting wash water, or
6
b) The water level in the machine is very low
and the wash water circulating in the pump and
plumbing is enough to lower the water level below
the probe.
6
The water level must be low for 5 seconds for
the cycle to be aborted. The heater output will,
however, be turned off immediately when the
water level is below the probe.
