Duxtop Induction Cooktop E3 Error — Fix

What Does This Error Mean?

E3 on a Duxtop means the supply voltage is too low for safe operation. Duxtop induction cooktops require a stable 120V supply (North American models). Plug directly into a wall outlet and avoid extension leads.

Affected Models

  • Duxtop 8100MC
  • Duxtop 9600LS
  • Duxtop 8300ST
  • Duxtop LCD 9900GB
  • Duxtop IBHF-011BW

Common Causes

  • Extension cord causing significant voltage drop under load
  • Circuit shared with other high-draw appliances causing voltage sag
  • Genuinely low supply voltage at the outlet
  • Internal power supply fault in the cooktop

How to Fix It

  1. Plug directly into a wall outlet.

    Extension leads — especially long ones or multi-strip adapters — cause voltage drop that triggers E3. Induction cooktops draw significant current and should always be on a direct outlet.

  2. Move to a different circuit.

    If the outlet is shared with a refrigerator, microwave, or other high-draw appliance, voltage sag when those devices cycle on can trigger E3. Try an outlet on a different circuit.

  3. Test the outlet voltage.

    With a multimeter or outlet tester, check that the outlet delivers the correct voltage (120V ±10% for North American models, 220–240V for international models). Persistent low voltage requires an electrician.

  4. If outlet voltage is correct and E3 persists, contact Duxtop support.

    E3 at correct outlet voltage with a direct connection points to an internal power supply fault. Duxtop offers a limited warranty — contact their support with the model number and purchase date.

Frequently Asked Questions

Can I use a Duxtop induction cooktop on an extension lead?

Duxtop strongly recommends a direct wall outlet connection. If an extension lead is absolutely necessary, use a heavy-duty lead rated at 15A or 20A with the shortest possible length to minimise voltage drop.

Why does E3 only appear when I turn the power up?

E3 at high power settings but not low settings is a classic sign of voltage sag — the circuit cannot supply enough current at full load without the voltage dropping. Move to a dedicated circuit or outlet.
