No hot water

Moni — Fri, 22 Jul 2022 15:56:01 GMT

Hi - My hot water isn’t working on schedule. It says it’s “on” but the background in the app is still grey. Also when I boost, again it says “on” but is grey still and there is absolutely no hot water. Can someone help me please 🥺

Hi @Moni, thanks for reaching out. The orange light when the hot water is on is an interactive interface. Sometimes it turns orange and shows the ON message, sometimes it just shows ON and remains grey. Do you have a system boiler or a combi one?

@Moni, I'm just checking in. Did you have a chance to see the message my colleague sent?

Hi George T i’m thinking I have system boiler . today I changed to manual and the hot water worked (simultaneously with the heating on the radiators), but when I changed to boost again, the stove did not turn on 😞

Thanks for letting us know. Could you tell us please whether the Bacteria Prevention feature is enabled? Please go into the thermostat on the wall's settings > Equipment > Continue > Bacteria Prevention. Does it say "enable" or "disable" ?

Thank you. Could you tell us please if going in the Nest app's settings > Hot water > Settings > Is it turned on of off? Could you send us a screenshot from there please?

Thank you. Could you tell me please if you go with the phone with Nest app on in front of the Heat Link and boost the hot water, can you hear a click coming from it after a few seconds? Same for turning it off?

Yes I’m hear a click for starting and off but unfortunately boiler not starting. 😔

Understood. Many thanks. Could you provide us please with a picture of the wiring underneath the Heat Link's case? Please turn the power off before removing the screw at the bottom of the Heat Link's case and send us a clear picture to see which wire goes into which terminal. Also, what type of heating system do you have? Combi boiler with hot water on demand or system boiler with thermostatic hot water control?

@Moni, thanks a lot for the images but the wiring is a tiny bit unclear. Would you mind providing me a few more pictures of the wires which go into the Heat Link terminals? Make sure to capture them from underneath as it will help us see better and understand what's going on. Thanks for understanding.

Hi Anda I think 🤔 this it’s better to see . Regards Monika

Thanks. We can see that all the wires from 2, 3,4,5,6 are the same colour. Could you maybe be able to tell us where is each wire going? The L, 2 and 5 should be all 3 linked together in order to function properly. Are they so in the picture?

However, as you explain to me, everything worked well for half a year. Additionally, if I turn on the manual setting, the house heating and water will work. So it seems to me that the specialist who was recommended by Nest had everything connected well. so how do you explain it to me?

Re: No hot water

DragosC — Mon, 08 Aug 2022 07:17:24 GMT

Understood. Thank you. I was just making sure everything was connected as it should. We've sent you an email. Please check on it and follow the instructions. Let us know when it's done please.
