My schott ceran class top stove keeps saying F1 on it and don't no how to fix it

Hi,
Here below we have aprocedure to try to see if you can save the ERC.
F1 touch pad / ERC test
This simple test will help determine
whether the ERC (Electronic Range Control or Clock) or the touch pad is
defective when F1 error code is present.

Note: Some models
incorporate the touch pad in to the ERC as a single assembly, in which case this
test is not necessary. Simply replace the ERC (Clock).

Warning: If
you feel in any way uncomfortable performing this test or making this repair,
please contact a qualified appliance repair technician.

1. Disconnect
power to the range (unplug the range power cord or turn the power off to the
range at the circuit breaker). It is very important that the power to the range
has been disconnected, so please double check before continuing.
2. Gain
access inside the control panel.
3. Disconnect the touch pad (also called
keypad or membrane switch) ribbon from the ERC.
4. Make sure there are no
lose wires, or anything else that may cause a short when power is turned back
on. Assemble the control panel back the way it was.
5. Turn the power back
on.
6. Wait for at least one hour to see if the F1 code comes back (usually
accompanied by a beeping sound).
7. If F1 comes back, replace the ERC. If it
does not, replace the touch pad.
