Flat iron troubleshooting
won't turn on, "Err", not heating
Quick fixes for the most common problems — most take under a minute. If none of them work, your iron is covered by our 3-year free replacement.
My iron won't turn on
Most often the safety plug (ALCI) has tripped. This is a standard US safety feature on the plug, not a fault in the iron.
- Find the plug block with two buttons, usually marked Test and Reset.
- Press Reset firmly until it clicks.
- Plug into a different outlet if it still won't start, then switch on again.

The display shows "Err"
"Err" means the iron's protection has stopped it heating.
- Switch off and unplug.
- Wait 60 seconds.
- Plug into a different wall outlet (not an extension strip) and switch on.
If "Err" comes back, start a claim — we replace it.
It turns on but doesn't get hot
- Check the safety plug: press Reset.
- Give it time to climb to the set temperature before the first section.
- Check the set temperature on the display and raise it if needed.
If it never reaches temperature, start a claim.
Can I take it abroad?
Check the voltage printed on the rating label near the cord before you travel. If it is dual voltage, you only need a plug adapter, not a converter. Never use a voltage converter with a heat tool unless the label says it needs one.
It pulls or snags hair
- Let it cool, then wipe the plates with a soft, damp cloth — product build-up is the usual cause.
- Use smaller sections and comb each one before pressing.
- Move at a slow, steady pace without squeezing hard.
How do I get a replacement?
Irons bought from vanessapro.com are covered automatically. Bought on Amazon? Register it first. Then start a claim with your order number and a photo of the rating label — a replacement ships free once approved.
How fast does shipping arrive, and where do orders ship from?
Every in-stock flat iron ships from our US fulfillment center — never from overseas — and most orders arrive in 2–4 days. Across 362 recent US deliveries (Oct 7 – Nov 2, 2026), the median from order to front door was 2.4 days:
- 19% arrived the next day
- 51% within 2 days
- 83% within 3 days
- 93% within 4 days
- 99% within 5 days
Orders usually leave the warehouse in about a day, and most are delivered by Amazon Logistics, which delivers 7 days a week. We ship to US addresses only; every iron has a US plug and works on 100–240V. Pre-orders ship Dec 1–3.
