Immersion heater stopped working after smart meter installation

Hi,

I had a smart meter installed on Friday and since then my immersion heater has not been heating up overnight. I’m on an economy 7 tarrif and the meter installed is a 5 terminal meter. The meter shows two rates and both meter readings have changed so it appears to be recording energy use on both tarriffs. Nothing has been tripped and I’ve also tried resetting the immersion heater but still no hot water. The boost function still works though. 

Has anyone had a similar experience/know what a fix might be?

Thanks!

Hi @cwebster17 yep that fits with the update on our side, which is that the ALCS command request to update the meter was sent on 23/03 but failed with a status of ‘E21’ (which means no response from the device). There are various reasons this may have happened and we asked someone to re-try it today.

 

That worked, so this should now be sorted!

If your storage heaters or water heater aren’t coming on at the correct times following a smart meter installation then you’ll need to contact our Support Team who’ll look into what the problem is.

I’ve had the same issue. We had a smart meter installed last week. When I called support, they told me that it shouldn’t have affected the immersion heater, or radiators, and that I should book an engineer to sort it out

@Martyb76 it’s probably just ECAUL/ALCS settings. This can be fixed remotely quite easily in most cases - the settings just need to be sent over.

Hello Experts,

I have same issue since last Wednesday. Everything was working well until smart meter got installed. 

Now No hot water and No heater since Wednesday.

Honestly, I am not at all technical in this matter. So, some of the terminologies are completely beyond my head.

I only know that without heater and hot water, this time is painful.

Please do us needful.

Thank You

Maulik

Hi @Maulik , if you have the same sort of meter (5 terminal) as the others, it maybe a similar update required. You will need to ask customer support to action

    Great. I will call them again on Monday. Surprisingly, They don’t work in weekends.

    Thank You @BPLightlog
