temperatures, fills, drains, and levels dont meet programmed values. In the event of a program
fault, the buzzer sounds and the display changes to show the fault:
LEVEL FAULT
Indicates a problem with the level sensing system. This could be a loose or cracked water level
tube, the level sensor, or the level sensing circuit. As long as the system detects a problem with the
level sensing system, the machine will be inoperable. The buzzer can be disabled with the RESET.
Refer to the EL6 Manual for possible remedies.
TEMP FAULT
Indicates a problem with the temperature sensing circuitry, temperature probe, or wiring. The ma-
chine continues to function, although auxiliary heating (if equipped) is disabled. The Temperature
fault indicator on the control panel will be illuminated.
WDT TEMP EXP
Indicates the programmed temperature was not reached within the allotted time. The most com-
mon cause is a malfunctioning auxiliary heating system. A short WDT time and very cold water
can also cause this problem. Pressing the START key will cancel the alarm and allow the program
to continue.
WDT LEVEL EXP
eached within the allotted time. The most common causes:
During Fill
Faulty water inlet valve
Low or no water pressure
Faulty drain valve
Problem with water level tube
Pressing START will continue the program, while RESET will cancel the program.
During Drain
Drain valve blocked
Drain hose blocked
