(Cont.)
6.3 Error Codes
All dishwashers perform a self-diagnostics when you push the POWER button to turn the
machine on. Watching the display provides information that will help you troubleshoot certain
problems.
The dishwasher self-diagnostics provide the following information:
1. All LED's illuminate indicating proper operation of the LEDs.
2. Display window(s) flash 888F.
Incorrect temperature readings can be checked by
observing the display test to see if all segments are working.
3. Error codes are displayed during self-diagnostics and
whenever the component is active during the automatic cycle:
E0F, E1F, E2F and E3F for machines programmed for
°
F.
E0C, E1C, E2C and E3C for machines programmed for
°
C.
(See next page for description of codes).
4.
LOF or LOC
is observed in the temperature display window.
All models may display "LO" because the temperature display indicates temperature
from 115
°
F/46
°
C and above. This is a normal condition during initial fill.
The
LOF
or
LOC
display at any other time may be an indication of a temperature problem
in the dishwasher and should be investigated before proceeding with warewashing.
