Bosch NIT8053UC - Manual (Page 20)

If an E Ö and a series of numbers appear in the display panel, there is a fault in the
electronic system. Turn the appliance off and back on at the fuse or circuit breaker.
Call customer service if the same display appears again.
If an F and a number flash in alternation on the displays, your appliance has
detected a fault. Refer to the following table for possible remedies.
Visual indication Fault Measure
F0 An internal error was
produced while the
cooktop was working. Disconnect the appliance from the power
source. Wait a few seconds before connecting it
again.
If the symbol appears again, call customer
service.
F2 The element is too hot
and has turned off. Remove the pans from the elements. F2
disappears when you acknowledge the display
(by pressing a touch key) and the element has
cooled sufficiently. Wait a few minutes until the
elements have cooled down slightly. If F2
appears again after the element is turned back
on, the cooktop is still too hot. Turn off the
elements and allow them to cool further.
F4 The pot or pan is too
close to the control
panel. Verify that the pot or pan is properly positioned
on the element. Verify that nothing hot is on the
touch key panel. Remove the hot item from the
control area. Wait a few minutes for the touch
key panel to cool. If F4 appears again after the
element is turned back on, call customer service.
F8 The element has been
in constant operation
for too long. The automatic shut off was activated.
Turn the element off.
You can turn it back on again immediately.
o1 The power voltage is
too low. Turn off the cooktop. Wait a few seconds before
turning it back on.
If the indication continues, contact your
electricity supplier.
o2/o3 The element has
overheated. It has been automatically deactivated to protect
your cooktop.
Wait a few minutes for it to cool down and switch
it back on again.
U400 The cooktop is
connected incorrectly. Disconnect the appliance from the power source
at the circuit breaker or fuse. Check the
connection and connect it again correctly.
If U400 appears again, call customer service.
The heat is switched on and off to regulate the temperature of the element; this
means that the red glow below the element is not always visible. When you select a
low heat setting, the element turns off more frequently, while at a higher setting it
only turns off occasionally. Even at the highest level, the element turns off and on.
As the element is heating up, there may be a light buzzing.
The brightness of the glow may vary from element to element. Depending on your
line of vision, the red glow may appear to extend beyond the marked edge of the
element.
These are technical characteristics and have no impact on quality or function.
