Burner 3: 210 mm - Ideal for your pan
Burner 4: Flexible zone - Compatible but less optimal

Important: The manual specifies that if your pan is smaller than the burner, it may not be detected by the cooktop. Also, ensure that the base of your pan (the magnetic diameter) is flat, completely centered on burner 3, and that it is induction compatible (ferromagnetic base). This optimal detection ensures stable operation of your cooker.

Question 5

Why won't my induction cooktop RI642CBB turn on despite clean buttons?

Accepted Answer

If your ROSIERES RI642CBB induction cooktop does not turn on, here are the checks to perform in this order:

1. Check the power supply

Make sure the cooktop is properly plugged into the mains (220-240V).
Check that the circuit breaker (minimum gap 3 mm) has not tripped. This is often the cause of a total power failure.
Test other devices plugged into the same outlet to verify if there is power.

2. Check the condition of the controls

Check if the “Lo” indicator is displayed. If so, the controls are locked. Press and hold the lock button (padlock) for 3 seconds to unlock.
Even if the buttons seem clean, ensure they are completely dry. Use the fleshy part of your finger (not the nail) to press the On/Off button (Ⓔ).

3. Correct ignition procedure

Press the On/Off button (Ⓔ). All indicators should display “ - ”.
You then have 1 minute to place a suitable pot and select the power, otherwise the cooktop will turn off automatically.

4. Check for error codes

If an error code appears (E2, E3, E4, E5, etc.), refer to the guide:

E2 or E3: Abnormal power supply voltage - check that you are indeed at 220-240V.
E4 or E5: Temperature sensor failure - contact a technician.

If no action works: After 1 month of use, if no indicator lights up and the cooktop remains completely inert, this may indicate an internal power fault or an electronic problem. Contact ROSIERES customer service for technical assistance.

Question 6

What power should I set when using 3 burners simultaneously?

Accepted Answer

With 3 burners active simultaneously, you must adhere to the total power limits of the cooker. The RI642CBB has a total installed power of 7,200 W and offers power levels from P1 to P5:

P1: maximum 2.5 kW
P2: maximum 3.5 kW
P3: maximum 4.5 kW
P4: maximum 5.5 kW
P5: maximum 7.2 kW (default setting)

With 3 active burners, we recommend operating in P3 or P4 to avoid overloads and safety shutdowns. For example, if you are using zones 1, 2, and 3 (respective powers 2,300 W, 1,200 W, and 1,800 W), the total approaches or exceeds 5 kW - you will need to limit the setting to P4 maximum. Check the indications displayed on the touchscreen to monitor your consumption in real-time, and reduce the power if you notice a slowdown or a safety alarm.

Question 7

What power should I set on my burners when using 2 simultaneously?

Accepted Answer

When using 2 burners simultaneously, there is no absolute prohibition. However, you must respect the total power limitations of the induction cooktop RI642CBB, which has an installed power of 7,200 W.

The cooktop features a power management system with 5 levels:

P1 to P4: limit respectively to 2.5 kW, 3.5 kW, 4.5 kW, and 5.5 kW max
P5: allows a maximum of 7.2 kW (default setting)

In practice, with 2 simultaneous burners, you can use:

Burners 2 and 4 (each up to 1,200 W): total 2,400 W, compatible with all levels
Burner 1 and any other: since zone 1 consumes up to 2,300 W in normal use, when paired with another burner you will generally remain under the limits of levels P3-P5

Warning: pairing burners 1 and 4 at P5 triggers a safety alarm after 30 seconds. Then reduce the power level to P3 or P4 to avoid automatic shutdown.

Question 8

How to repair or eliminate a micro-scratch on the induction cooktop?

Accepted Answer

Micro-scratches on the glass of the induction cooktop are generally superficial and do not affect the operation of your ROSIERES RI642CBB.

To prevent scratches:

Always use a soft cloth and a non-abrasive cleaning product for maintenance
Lift your utensils rather than sliding them across the glass surface
Avoid scouring pads, abrasive synthetic sponges, and aggressive cleaning agents that can damage the glass
Do not place wet utensils or those with residues that could be slippery

For existing scratches:

If the scratch is superficial and only affects the aesthetic appearance, no intervention is necessary. The glass surface still functions normally. To minimize the appearance, keep the cooktop clean with a damp soft cloth.

If the scratch is deep or affects the safety of the cooktop, contact ROSIERES customer service for an assessment.

Question 9

How to remove grease splashes from the touch controls?

Accepted Answer

Cleaning grease splashes from the touch controls

Grease splashes on the touch controls of your ROSIERES RI642CBB can make the appliance difficult to use. Here is the recommended procedure:

Turn off the plate at the circuit breaker or the stop button
Immediately blot the overflow with a soft cloth
Wipe with a damp cloth or sponge - only dampen it with clean water
Dry thoroughly with paper towels
Turn the power back on

Important notice: A liquid present on the touch controls can cause malfunction. The plate may beep and turn off by itself, and the controls may not respond. Ensure everything is completely dry before turning the appliance back on.

For greasy spills on the ceramic surface:

Gently scrape at a 30-degree angle with a suitable scraper if the grease has dried
Then clean with a clean cloth
Apply a ceramic cleaner when the plate is warm
Rinse and wipe with a clean cloth

Absolutely avoid: abrasive pads, scouring powders, or steam cleaners that could scratch the glass surface.

Question 10

A burner turns on by itself without me activating it - for example, I manipulate burner 1 and burner 2 turns on automatically

Accepted Answer

This phenomenon usually occurs when multiple cooking zones are activated simultaneously or in close succession. On the ROSIERES RI642CBB stove, which has 4 induction zones spread across the glass, it is possible that your finger or hand accidentally brushes against the sensor of another zone while manipulating the controls.

Here’s how to check and correct:

Check the surface of the cooktop: make sure it is perfectly dry and clean. Moisture or residues can create false capacitive contacts.
Handle the controls precisely: when adjusting one zone, avoid brushing against the sensors of adjacent zones. Zones 1 and 2 are close to each other.
Check for wet fingers: if your finger is wet, it may inadvertently activate multiple sensors at the same time.
Test the Lock function: you can use the lock function on your stove to block the controls during cooking, which will prevent any accidental activation.

If the problem persists without any action on your part, there may be a detection fault in the zone. In this case, contact ROSIERES customer service for a diagnosis.
