Error code E01 has no meaning of its own. It is simply the first entry in one manufacturer’s error table, and each maker fills that table differently — so E01 on your charger is unrelated to E01 on any other brand, and often to E01 on another model from the same brand. The only document that can decode it is the manual or support table for your exact model. Anything else is a guess wearing a code’s clothing.
Key Takeaways
- E01 is a position in one maker’s table, not a diagnosis: no cross-brand or cross-model meaning exists.
- Search results mix brands’ tables; the spread of meanings is proof the string alone says nothing.
- Decode only from your exact model’s manual, and follow its table’s stated action.
- Photograph the code and record the model before any reset — support works from the record.
Why Search Results Cannot Decode It for You
Search “E01 EV charger” and the results mix every maker that uses the string. Across brands’ published tables, the first code slot has been assigned to unrelated territories — a supply problem on one maker’s list, a temperature stop on another’s, a communication failure on a third’s. That spread is not a clue about your charger; it is proof the code carries no shared meaning. Acting on the wrong table can send you checking the supply for a fault reported somewhere else entirely.
Even within one brand, tables change between models and hardware generations. A code list is written for a model and revised with it. The string is the same; the sentence it belongs to is not.
The Only Dictionary: Your Model’s Table
- Find the manual for the exact model — the name on the rating label, not the product family. Makers publish manual PDFs on their support pages; search the document for the code exactly as displayed.
- Match the whole display, not just the code: some units pair a code with a light pattern, and the table is keyed to the combination.
- Follow the table’s stated action. Manuals sort their codes into owner-level checks and service-level faults. If yours lands in the service column, the table has answered you: the next step is support, not experimentation.
- If the manual is lost, the manufacturer’s support route replaces it. Give them the model and serial number and they will work from the same table.
Record the Code Like Evidence
| Field | What to capture | Why it matters |
|---|---|---|
| The code, exactly | Every character as displayed — photograph the screen if you can | Similar codes are different entries; memory edits them within hours |
| The model | Model and serial number from the rating label | Identifies which table — and which hardware generation — applies |
| The moment | At plug-in, mid-session, or after a setting change; the weather if outdoors | Splits supply, connection and session causes before anyone guesses |
| The sequel | Whether one power cycle cleared it, and whether it returned | A returning code is a different case from a one-off — support triages on it |
Record before you reset: a cleared display takes the evidence with it. One controlled power cycle, after recording, is a reasonable test — the discipline our checklist for a charger that is not working sets out. A returning code is a support case; how suppliers handle documented faults is covered in our guide to common EV charger faults.
EVDANCE Models and Error Codes
EVDANCE states its models’ features on their pages and puts each unit’s codes in that unit’s manual — there is no public cross-model EVDANCE code table, and this article will not invent one. The EV-ACS3210E is stated with an app and energy monitoring, and the EV-ACT3204E wallbox with RFID and app; where an app keeps session records, those records belong in your evidence. If your EVDANCE charger shows E01 — or any code — photograph it, note the model, and send both through the contact page. Support reads it against your model’s own table — the only reading that counts.
Frequently Asked Questions
A forum says E01 means one specific fault. Can I trust it?
Only if the post is about your exact model — and even then, verify it against your manual’s table. Forum answers rarely name the model precisely, and a correct answer for one charger is a wrong answer for yours.
The code cleared after a restart. Do I still need to record it?
Yes — keep the code, the model and the date. If it returns, two dated records turn a vague support message into an identification. A single unrepeated code may be transient; the record is what lets anyone tell.
My charger shows a code but still charges. Should I stop?
Treat any fault display as a stop until your model’s table says otherwise. A code means a check failed or a protection acted; charging past it trades a recorded fault for an unrecorded risk.
