Disconnect the product from the power source
before starting this procedure.
This section defines the error codes in a E Series Oven.
The error code table shows a "priority" for each error.
•
Priority 1:
Errors considered safety-related, or of such
catastrophic scope that the control is considered
inoperable. These errors are continuously shown to the
user, indicating that a service call is required. No user
functions will be allowed, and any active functions will be
canceled upon generation of the priority 1 error. The error
can be canceled, but will regenerate if the condition that
caused the error still exists.
• Priority 2:
Errors are shown to the user only during an
active cooking/clean mode, or upon an attempt by the user
to enter a cooking/clean mode. The criteria for these errors
is that they are likely to limit the proper functionality of the
system and would normally cause some customer
dissatisfaction. These errors can be canceled and are not
shown again until the user again attempts to start a mode.
Any active function in the cavity for which the error has
scope are canceled upon generation of the priority 2 error.
Errors with system-wide scope will apply to both cavities;
errors with cavity scope will apply only to the appropriate
cavity unless otherwise noted.
• Priority 3:
Errors are defined as errors that could cause
some possible or conditionally impaired functionality, most
likely never to be noticed by the end user. These errors,
although logged internally, are never be shown to the end
user, and are generally not able to be canceled by the end
user.
