About the LG CBEW3013*E
This guide covers the LG CBEW3013*E, a 30 in. radiant cooktop listed as ENERGY STAR certified. It measures 30.7 in. wide and 21.1 in. deep, with a height of 4.31 in.
Radiant elements sit under a smooth glass-ceramic top and heat the pan through the glass. They work with any flat-bottomed cookware, but the glass stays hot for a while after the element is switched off. The cooking surface has 4 cooking zones, the most powerful rated at 2,500 W and the largest 9.96 in. across.
Listed features include dual-concentric zones that switch between two diameters, active cooling for the electronics, touch controls, and Wi-Fi connectivity.
Rated annual energy consumption for the cooking top is 195 kWh, about $33.15 a year at $0.17/kWh.

Safety information
- This appliance requires a 240 V circuit (the certification record lists 29.6 A). Have the electrical connection made by a qualified electrician according to the installation instructions and local code. Never use an extension cord or adapter.
- Never leave cooking unattended on high heat, and keep pot handles turned inward, away from the edge.
- For a grease fire on the cooktop, turn off the zone and smother the flames with a lid or baking sheet. Never use water and never carry a burning pan.
- Do not store flammable items, plastic utensils or aerosol cans on or above the cooking surface.
- Wear close-fitting sleeves; loose clothing can catch fire on a hot element or pan.
- Never use the glass top as a cutting board or storage shelf. If the glass is cracked, switch off the breaker and stop using the cooktop until it is repaired.
Installation and first-time setup
According to the certification data, this cooktop is 30.7 in. wide, 21.1 in. deep, and 4.31 in. tall (top to bottom of the unit). The countertop cutout is a different, smaller dimension — always cut to the template or cutout drawing in the installation instructions.
- Prepare the cutout
Cut the countertop opening to the template dimensions and verify the minimum clearances to the cabinet doors, drawers and any wall cabinets above as given in the installation instructions.
- Check the electrical supply
Provide a dedicated 240 V circuit using the breaker size and wire gauge the installation instructions specify (the certification record lists an amperage of 29.6 A for this model). New installations generally require a four-wire connection (two hots, neutral and a separate ground).
- Connect the cooktop
Route the flexible conduit to a junction box within reach of the cooktop and make the connection with the breaker off. Do not shorten or kink the factory conduit.
- Keep the ventilation path clear
This cooktop uses active cooling for its electronics. Maintain the clearance below the cooktop specified in the instructions, and do not store items in a drawer directly underneath unless the instructions allow it.
- Seat and secure
Lower the cooktop into the opening, center it, and fasten the hold-down clips or brackets so the glass sits flat without stress. Remove any protective film before first use.
Using your cooktop
Cooking zones on this model
| Zone | Diameter | Power |
|---|---|---|
| Zone 1 | 6.42 in. (16 cm) | 1,200 W |
| Zone 2 | 6.42 in. (16 cm) | 1,200 W |
| Zone 3 | 9.96 in. (25 cm) | 2,500 W |
| Zone 4 | 9.21 in. (23 cm) | 2,200 W |
Match the pan to the zone: the base of the pan should cover the zone marking, or be no more than about 1 in. larger. Use the highest-wattage zone for boiling large pots and searing, and the smallest zones for sauces and simmering.
Cooking on a radiant glass top
- Use flat, smooth-bottomed pans that match the element size; rough cast-iron bottoms can scratch the glass.
- At lower settings the element cycles on and off to hold the temperature — the glow brightening and fading is normal.
- The glass stays hot after switching off. Use that stored heat by turning the element off a few minutes before the food is done.
- Wipe up sugary spills promptly (carefully, with a scraper and oven mitt) — melted sugar can pit the glass if it cools on the surface.
Specialty zones
- Dual-concentric zone
- Switch between a small and a large ring to match the pan size.
Controls
This model uses touch controls. Keep the control area clean and dry — water, spills or a pan resting on the panel can make touch keys unresponsive or switch a zone off. Use the controls lock when cleaning and whenever children are around.
Smart features
The certification record lists these smart capabilities: cooking progress monitoring, syncing with a compatible vent hood, Wi-Fi connectivity, and status notifications. Set them up through the manufacturer's app; remote functions are designed for convenience and should never replace supervising active cooking.
Care and maintenance
| When | What to do |
|---|---|
| After each use (once cool) | Wipe the glass with a damp cloth. For residue, use a ceramic-cooktop cleaning cream and a non-scratch pad — never steel wool, abrasive powders or glass cleaner with ammonia on a warm surface. |
| As needed | Remove burned-on deposits with a razor-blade scraper held at about a 30° angle, then polish with cooktop cream. |
| Monthly | Clean the control knobs or touch panel with a soft cloth and mild detergent; dry thoroughly. |
Troubleshooting
Many cooktop problems are caused by cookware, settings or the power supply. Try the checks below before scheduling service.
| Problem | Possible cause | What to try |
|---|---|---|
| Nothing works | Breaker tripped (240 V appliances use a double breaker); controls locked; power outage. | Reset the breaker fully off and on; unlock the controls; check other appliances on the same panel. |
| Element turns off and on by itself | Normal cycling to hold lower settings; temperature limiter protecting the glass. | No action needed. Use flat pans that match the zone size so the limiter does not trip early. |
| Scratches or shiny marks on the glass | Rough pan bottoms, sliding pans, or metal marks from aluminum or copper pans. | Metal marks usually come off with cooktop cleaning cream; scratches are permanent, so lift pans instead of sliding them. |
| Food heats slowly or unevenly | Warped or undersized pan; wrong zone. | Use a flat pan that matches the zone diameter. |
| Touch controls do not respond | Water or spills on the panel; controls lock on; pan resting on the controls. | Dry the panel, remove objects, and turn off the lock. |
| A code appears on the display | The control has detected a fault. | Note the code, switch the breaker off for a minute, then on. If the code returns, look it up in the code table in your manufacturer's manual. |
Energy use and running costs
The LG CBEW3013*E has a rated annual energy consumption of 195 kWh for its cooking top, measured under the U.S. Department of Energy test procedure. At $0.17 per kWh, that is about $33.15 per year, or $2.76 a month.
Low-power (standby) consumption — the energy used by displays and electronics when nothing is cooking — is listed as 4.01 kWh/yr for the cooking top, worth about $0.68 a year.
To cut energy use, match pan size to the element, keep lids on pots, and use residual heat by switching the element off a few minutes before food is done.
