Error D4 prepay elec meter?!


Just switched to bulb and error D4 (suggesting the key is programmed incorrectly) is showing when trying to put money on the meter.

Bult - rather helpfully - are only open until 1800.

Does anyone know how to sort this?


Errors D2, D4, D6
Your new key isn’t talking to the meter correctly.
Get in touch, we’ll issue you an 8-digit TAG code for you to reprogramme your key.
