Incoming supply issue
Easee Incoming supply issue on an EV charger: supply voltage outside 207 to 253 V
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
The Easee charger measured a supply voltage above 253 V or below 207 V. It resets on its own once it sees a stable 207 to 253 V; if it keeps happening, Easee says to contact your electricity supplier.
Safety first
Stop and check this first
- Do not open the charger or the consumer unit to measure voltage yourself. If the alert persists, Easee says to contact the electricity supplier.
Safe checks you can perform
- Automatic reset
- Time pattern of the alert
- Voltage measurement at the origin and the charger
Leave these tasks to a qualified professional
- Do not attempt this professional task: Supply voltage logging
- Do not attempt this professional task: Voltage drop on the charger circuit
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Supply voltage logging
What they doThe electrician measures voltage at the installation origin and, if intermittent, leaves a logger for several days.
They must show youreadings or a graph with the times outside 207 to 253 V.
In writingvalues, logging period and whether the evidence goes to the supplier.
Voltage drop on the charger circuit
What they doMeasures charger voltage with and without load and checks connection tightness on the circuit with it isolated.
They must show youthe voltage difference between no load and load.
In writingconnections checked, measured values and conclusion.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Automatic reset
- Who:
- you, no tools.
- How:
- wait with the car plugged in for the charger to measure a stable voltage again, as Easee describes.
- Result that matters:
- whether charging resumes on its own.
- If it resumes:
- the problem was temporary; note the time.
- If it does not resume or keeps coming back:
- voltage is still out of range; keep logging.
- Evidence to keep:
- app screenshots with date and time.
Evidence: Error messages in the app
Time pattern of the alert
- Who:
- you, no tools.
- How:
- for several days, note when the alert appears and whether it matches other loads in the home.
- Result that matters:
- whether it depends on time or on internal load.
- If it matches time windows unrelated to your use:
- points to the network; take it to the supplier.
- If it matches heavy loads in the home:
- points to the internal installation.
- Evidence to keep:
- table of dates, times and loads.
Evidence: Error messages in the app
Voltage measurement at the origin and the charger
- Who:
- qualified electrician.
- How:
- measure voltage at the main consumer unit and at the charger, with and without load, and if needed fit a logger.
- Result that matters:
- whether voltage arrives wrong or drops inside the home.
- If it arrives out of range at the consumer unit:
- confirms a network problem.
- If it only drops on the charger circuit:
- confirms an installation problem.
- Evidence to keep:
- report with readings and log.
Measuring mains voltage at the consumer unit is electrician work.

Where this code applies
A code is meaningful only inside the right product and version context.
Primary scope
- System
- EV charging
- Brand
- Easee

- EV charger
Known code variants
- Easee Incoming supply issue
- Easee problema de suministro entrante
- Easee supply voltage error
- Easee tensión alta baja
- Easee voltage too high too low
What it means
Easee defines Incoming supply issue as supply voltage to the property that is too high (above 253 V) or too low (below 207 V), with 230 V as the standard. The charger resets automatically once it measures a stable voltage between 207 and 253 V. The problem can come from the network or from the internal installation, and the alert does not say which.
Warnings and stop conditions
- Mediumeditorial warning
Do not open the charger or the consumer unit to measure voltage yourself. If the alert persists, Easee says to contact the electricity supplier.
Evidence: Error messages in the app
Symptoms and causes
Probable causes · in order
- Network voltage out of rangePossible
Easee refers you to the electricity supplier if it persists. If it appears at certain times or affects neighbours, the origin is the network.
Evidence: Error messages in the app
- Voltage drop in the internal installationPossible
If voltage only drops while the charger delivers power, a loose connection or undersized circuit can cause it. An electrician tells them apart by measuring at the consumer unit and the charger.
