What does the dE error mean on an induction cooktop?#
dE means the cooktop is stuck in showroom demo mode: the panel lights up, beeps and responds to taps, but the cooking zones never actually deliver any heat. It is not a fault and nothing has broken, so it is not urgent — the first thing to check is whether the cooktop was recently installed, moved, or had a power cut, because that is when demo mode tends to switch itself on. dE is documented on Frigidaire, Electrolux, GE and other induction cooktops that carry a retail demo mode. The table below lists the handful of situations that produce it, all of which come down to demo mode being active rather than any damage to the appliance.
dE on an induction cooktop: what it means and what to check#
An induction cooktop shows dE when the cooktop is running in showroom demo mode, so the panel lights and beeps but the zones never actually heat.
| Likely cause | What's happening | How likely | First thing to check | Fix it yourself? |
|---|---|---|---|---|
| Showroom demo mode left switched on | the cooktop is in a retail display mode that drives the lights and tones but disables real heating | Most likely | follow the manual key sequence to exit demo mode (often the power key held with a lock key) | Often DIY |
| Demo mode re-armed after a power cut | a stored demo flag switches display mode back on when power returns | Possible | repeat the exit-demo key sequence once power is restored | Often DIY |
| The exit key combination mistimed | a mistimed press leaves demo mode active instead of clearing it | Less likely | read the exact button order and timing in the manual and try once more | Often DIY |
| Fastest thing to try first: Follow the manual key sequence to exit demo mode (often the power key held with a lock key). | ||||
| If dE keeps returning: A stored demo flag switches display mode back on when power returns — repeat the exit-demo key sequence once power is restored. |

How to clear the dE error yourself#
This one is genuinely a do-it-yourself fix, because the cause lives in a setting rather than in the hardware. Start by confirming the symptom: the display and controls work normally but no zone gets warm, which is the fingerprint of demo mode. Next, look up your model's exit sequence — most induction cooktops leave demo mode through a specific key combination held for a few seconds within a short window after power-on, and mistiming that combination is the usual reason a first attempt fails. Cut the power at the breaker for a minute, restore it, and enter the exit sequence promptly and deliberately. If demo mode keeps re-arming after every power cut, or the exit combination will not take no matter how carefully you time it, stop there — at that point the control needs a technician, and there is never a supply-voltage or electrician question with a demo-mode code.
When the dE error needs a technician#
Almost every dE clears without a technician, because it is a mode you toggle rather than a part you replace — the exit key combination is designed for the owner to use. There is no electrical hazard and no electrician involved, since the zones are simply held off. The only time dE points at the appliance is when the documented exit sequence genuinely will not disengage demo mode, or the cooktop re-enters it on its own after every restart. That behaviour suggests the control board is not saving its state correctly, which needs a technician with the service documentation to confirm before any board is considered. Until then, keep working the exit sequence — the fault, if any, is in the control, never in the cooking surface.

Induction cooktop dE error: frequently asked questions#
What does the dE error mean on an induction cooktop?#
dE tells you the cooktop is in showroom demo mode. The controls and display behave normally, but the zones are deliberately kept from heating so a store unit can be shown off safely. It is a setting, not a breakdown, and it clears the moment demo mode is exited through the model's key sequence.
Can showroom demo mode left switched on trigger the dE error?#
Yes — that is the single most common cause. A cooktop that came from a display floor, or was set up by an installer who left demo mode on, will show dE until the mode is turned off. Nothing is wrong with the appliance; it simply needs its demo setting disengaged with the documented exit combination.
Does demo mode re-armed after a power cut cause the dE code on an induction cooktop?#
It can. On some models a power interruption re-arms demo mode, so dE reappears after an outage even though you cleared it before. Re-enter the exit sequence after power is restored. If it keeps coming back every single time the power blinks, the control may not be storing the setting, which is worth a technician's look.
Should I check for the exit key combination mistimed first?#
Yes. Most demo-mode exits only work within a short window after the cooktop powers on, so a mistimed or too-slow key combination is the usual reason a first attempt fails. Cut and restore power, then enter the exact sequence for your model promptly and hold it for the specified time before assuming anything is wrong.
Can I clear the dE error myself?#
In almost all cases, yes. dE is an owner-clearable mode, not a repair. Find your model's demo-mode exit combination, restore power, and enter it within the start-up window. No tools or parts are needed, and the zones return to normal heating as soon as demo mode is switched off.
Is it safe to keep cooking when dE shows?#
There is no danger, but you also cannot cook, because demo mode holds every zone off — the cooktop will light and beep but never heat. Nothing is overheating or at risk while dE is on screen. You simply need to exit demo mode before the cooktop will cook anything.
