Café Induction Cooktop Flashing F: Troubleshooting... | appliancefaults.com

Technical Background:

The cooktop's Microcontroller Unit (MCU) monitors the cooking zones for compatible cookware. It sends a low-voltage signal to the sensor under each cooking zone. This signal checks for the presence of a ferrous material (magnetic) object of sufficient size. The returning voltage is then interpreted by the MCU. An 'F' code means that the MCU is not reading the correct voltage indicating it does not consider the cookware suitable for induction heating.

Symptoms:

The Café induction cooktop displays an 'F' error code and does not heat up. This usually happens immediately after turning on the cooktop or placing cookware on the burner.

Possible Causes:

Non-ferrous cookware detected on cooking zone
Cookware not centered on cooking zone
Insufficient cookware base diameter
Cookware base is warped, preventing proper contact
Sensor malfunction within the induction cooktop

Solution:

1

Verify Cookware: Ensure cookware is induction-compatible (magnetic base). Test with a magnet; if it sticks firmly, it's suitable.
2

Center Cookware: Position the cookware directly in the center of the cooking zone.
3

Check Cookware Size: Use cookware with a base diameter that matches or slightly exceeds the indicated zone size.
4

Inspect Cookware Base: Check for warping or damage on the cookware base. Use a straight edge to confirm it's flat.
5

Power Cycle Cooktop: Turn off the breaker to the cooktop for 5 minutes, then turn it back on. This can reset the control board.
6

Sensor Test (Advanced): If the error persists, a technician should use a multimeter to test the sensor resistance within the cooktop when cool and with some heat applied.
7

Control Board Replacement (If Needed): After validating sensors, a faulty control board might need replacement by a certified technician. Use a 1/4-inch nut driver for access.

Safety Warning:

Disconnect power at the breaker panel (LOTO - Lock Out Tag Out) before performing any repairs. Induction cooktops operate at high voltages (240V AC) and can cause serious injury or death.

Prevention:

Use only induction-compatible cookware. Regularly clean the cooktop surface to remove debris that could interfere with the sensor. Check the cookware base periodically for warping.

Expert Tip:

Some Café induction cooktops have a service mode that allows you to test individual components. Refer to the service manual for the specific key sequence to enter service mode on your model. This may involve pressing and holding specific buttons simultaneously for a set amount of time (e.g. Power and Timer buttons for 5 seconds).

Frequently Asked Questions

•How do I know if my cookware is induction-compatible?

The easiest way is to test the bottom of the pan with a magnet. If the magnet sticks firmly, it's generally induction-compatible. Look for an induction symbol on the cookware.

•What is the typical resistance value for the induction sensor?

Sensor resistance values vary by model. Consult the Café service manual for your specific cooktop. Typical values may range from 500 ohms to several kilo-ohms at room temperature.

•Where can I find the service manual for my Café induction cooktop?

Service manuals can often be found online through appliance parts retailers or directly from GE/Café's website. Search using your cooktop's model number.
