Flashing red light on charger

[Pagemakers]

I have a Tesla wall charger and the indicator light on it is green when not it use. I’ve had it for about 3 years.

When I plug my car it the green light changes to a permanent flashing red and the car doesn’t charge.

I have reset the charger a dozen times and also reset the circuit breaker and the problem persists. The car charges fine on other chargers.

Any ideas to resolve would be appreciated.

Red light probably means a ground fault. Has anything damaged the earth rod connection ?

 

[Pagemakers]

Not to my knowledge. Wouldn’t the breaker pop if there was some kind of ground fault?

It will be covered in the manual

Have you tried the old 'turn it off and back on again' (at the fuse board), maybe for 5mins?

 

[Pagemakers]

Thanks for your replies but nothing helps. The manual and the link refer to the red lights flashing between 1&6 times but nothing for continuous red flashing.

I have turned it off at the fuse board also.

Think I need to make an appointment with Tesla.

Huh? Continuous red flashing. Isn't that flashing once?

ie
single flash - break - single flash - break etc... which sounds like what you have
double flash - break - double flash - break - not what it sounds like you have etc

So ground fault, or over temperature protection depending on other lights

hmmm, my money on over temperature if its in the sun.

 

[Pagemakers]

Ah, single flash. I see what you mean. It’s not overheat because it’s in the garage.

Tried connecting to its Wi-Fi and see if it gives you any info on the fault?

 

[Pagemakers]

Don’t think mine has wifi. It’s about 5 years old

 

[Pagemakers]

It’s only flashes red when it’s plugged into the car.

Tesla just cancelled the home visit. Apparently they don’t come out for charger issues.

I got a warranty replacement as the warranty is valid for 4 years.

...and it's in Manchester.

 

[Tony Hoyle]

...and it's in Manchester.

So.. water ingress?

 

[Pagemakers]

Nope. In a nice warm garage away from the Manchester weather!

This is my issue.

For Six Red Blinks

Flashing red lights 6 times means there’s too much voltage or poor grid quality detected. If you’re using the level 2 charger, the power supply should be nominal 200-240 volts. Have an electrician remove the Wall Connector from the wire box and confirm that voltage readings are correct.

 

[ACarneiro]

Can you have access to a volt meter and check your voltage at any plug socket in your home?

 

[Pagemakers]

I think so.

That said, nothing else is messing up in the house and I can still charge my car using the Tesla 13amp plug charger.
