Display Description Cause/Corrective Action
E Ht
Heat Alarm Error Programmed heat alarm time of 120 minutes or other program-
med length of time is exceeded. Turns off heater output for re-
mainder of cycle.
E oP
Open Temperature Sensor Error Control senses temperature less than 0°F [-18°C] in machine
equipped with temperature sensor. Heater and thermistor related
operations are disabled for remainder of cycle.
E SH
Shorted Temperature Sensor Error Control senses temperature greater than 220°F [104°C] in ma-
chine equipped with temperature sensor. Heater and thermistor
related operations are disabled for remainder of cycle.
E ro
Rotation Sensor Error Invalid signal received from Rotation Sensor. Control will acti-
vate coast times to complete cycle.
E FS
Frame Stability Switch Error Control detects Frame Stability Switch open. End cycle.
E db
Drive Balance Switch Error Control detects VFD Balance Switch input closed at start of drain
step. End cycle. Power down machine to clear.
E Ld
Water Leak Detection Error (Drain Valve) If control senses a drop in water level during diagnostic testing.
Power down machine to clear. When error occurs during a cy-
cle, E Ld is displayed for one (1) minute after opening the door
at the end of the cycle and lights the right-most decimal point*
on the display. When the error occurs during the test, E Ld is
displayed immediately after the test until the machine is pow-
ered down to clear the error.
E LF**
Water Leak Detection Error Control senses an increase in water level during diagnostic test-
ing. Power down machine to clear. Control shows error after door
is open (when cycle is completed) for one minute or after test has
been completed, the right-most decimal point on display lights*
and the error information will be logged in audit data.
E Sd
Slow Drain Error Control senses the time required to drain the water is too long,
the control shows error after door is open (when cycle is com-
pleted) for one (1) minute, the right-most decimal point on dis-
play lights* and the error information will be logged in audit da-
ta.
E Sd
Slow Drain Error Control shows error after door is open (when cycle is completed)
for one (1) minute, the error information will be logged in audit
data.
Ed01**
SPI Communication Error Front End control cannot communicate with motor drive. Power
down, verify input power and 6-pin communication connection
on drive and Front End control, power up and try again.
Ed02**
DC Bus Error The control detects the DC bus is too high. Power down, verify
line voltage is within specification, power up and try again.
Ed03**
Tachometer Error The drive detects the tachometer input is damaged during power
up or no tachometer signal is detected after initiating motor out-
put. Power down, verify H3 on drive and tachometer connections
on motor, power up and try again.
