EV charger faults common to all brands

Most home chargepoints have no screen and no fault codes — the status is in a light, and the decoder differs by make. What is genuinely the same across all of them is the regulated behaviour they are required to have, which is also the single biggest cause of owners thinking a working charger has failed.

This page is not myenergi zappi's numbered table or Ohme's LED key. Red means stop on some units and connected-and-waiting on others; both are published UK positions. If you have a light pattern or an app message, use the brand hub. If the charger simply did nothing overnight, start here: since 2022 a smart chargepoint must apply a random delay of up to ten minutes and ship with a default off-peak schedule.

A unit that trips and will not start is often reporting the incoming supply — open-PEN detection — rather than a broken charger. Repeatedly resetting it is the wrong response. Installing or altering a chargepoint is notifiable electrical work under Part P; the person to call is a scheme-registered electrician, not a gas engineer, and there is no oil-heating angle here.

Named-brand hubs in this category: myenergi zappi and Ohme. Those pages carry the manufacturer’s own table; this one does not replace them.

How these displays appear

Take the colour with the brand rather than on its own. Red means stop on some units and means connected and waiting for the car on others, and those are both published positions from manufacturers selling in the UK. Where there is an app, it will nearly always give a fuller message than the light does, and it is worth looking there before drawing conclusions.

What a reset actually does

The owner-safe reset on every brand in this category is the same: switch the charger off at its own breaker in the consumer unit, wait, and switch it back on. Manufacturers give different waits: Ohme say five seconds after an RCD activation and fifteen minutes to bring an offline unit back, bp pulse say at least ten seconds at the circuit protection device and then two minutes for the start-up sequence, and Easee allow one restart at the breaker for a solid red lockout and none for flashing red. Unplugging and re-plugging the vehicle is also sanctioned everywhere. Nothing beyond that is an owner action on any brand — Ohme put it plainly, that there are no user-serviceable parts and the unit should not be opened, repaired, tampered with or modified.

CodeWhat it meansSeverity
Not charging on scheduleAlmost certainly the law rather than a fault. Chargers are required to apply a random delay of up to ten minutes and to ship with a default off-peak schedule.Usually simple to fix
Charger keeps trippingDo not keep resetting it. UK chargepoints are required to detect a dangerous supply fault, and repeated tripping may be the charger reporting your electricity supply.Stop — call an engineer
Red lightDo not assume red means broken. Some manufacturers publish it as a stop condition; Ohme publish steady red on their Home and Go as connected and waiting for your car.Get it checked
Cable stuck in the socketAlarming and usually mechanical. The counterintuitive fix that manufacturers publish is to push the plug further in, not to pull harder.Get it checked
Charging slower than expectedUsually the charger sharing the house supply, a solar mode doing its job, or a CT clamp problem — Ohme publish a specific fallback to 16 amps.Usually simple to fix

These pages apply across types. The split is by how the appliance is built, not by badge.
