Frypot temperature is more than 410ºF
(210ºC) or, in CE countries, 395ºF
(202ºC).
This in an indication of a malfunc-
tion in the temperature control
circuitry, including a failure of the
high-limit thermostat.

IGNITION FAILURE.
Open drain valve, failed computer,
failed interface board, open high-limit
thermostat.
This indicates that the fryer is not
heating. It is displayed if the fryer
loses its ability to heat oil. It is also
displayed when the oil temperature
is above 450°F (232°C) and the
high-limit thermostat has opened,
halting the heating of the oil.
Verify that the drain valves are fully
closed.
