7. System failures
7.1 Failure types
Regarding the system there are four types of failures depending on their gravity and the impact they may
have on the behaviour of the appliance:
7.1.1 Failure type 1
These failures are the ones that affect only one cooking zone. The user may continue using the other
cooking zones. When this type of failure occurs then USIF becomes insensitive to the subsequent
changes of settings on that cooking zone. If the user presses the buttons related to the defective zone
then a long beep is emitted.
Every failure type 1 (that concerns one cooking zone only) is only shown on the display of that cooking
area. Supposing to have the error coded with F21 on zone #1, then it will be shown intermittently an “F”,
a “2” and a “1” on that display. (See pictures below - Each frame is shown for one second on the USIF.)
7.1.2 Failure type 2
Failure type 2 usually comes from IPCs (there could be some exceptions). These failures affect the
whole IPC, in any case the user could go on using the cooking zones that belong to the other IPC.
When this type of failure occurs the USIF becomes insensitive to subsequent changes of settings on that
IPC. If the user presses the buttons related the IPC where the failure is, then a long beep is emitted.
