POSSIBLE INSTRUCTION AND ERROR INDICATORS
The diagrams on these pages illustrate what a customer may see in the LCD if the appliance needs attention.
NOTES:
• To clear instruction indicators (See Figures 3-52 & 3-53) and restart the appropriate timer, the instructions must be
followed, then press the appropriate key or reset button as described.
• For thermistor errors described below (See Figures 3-54 & 3-55): Thermistors can be tested by submersing them
in a glass of ice water for approximately five (5) minutes, then checking for 30,000 to 33,000 ohms.
• To clear error indicators and Fault Codes (See Figures 3-54 to 3-59) the problem must be corrected, then press
the ALARM key for fifteen (15) seconds (See Figure 3-60). Failure to clear Fault Codes will result in the highest
priority error indicator reappearing in the LCD when the unit is switched back ON.
