Dear All,
Please kindly advise, i don't know what else to do! Had new boiler Vaillant 424 heat only open vent boiler installed with new flue and filter, new pump, plus new Hive. Did full power flush of all 5 radiators before the installation. It has been 10days and boiler stil not working properly. I tried to sum up points below, could someone kindly give an advise as the gas engineer now says he doesn't know what to do and do not wan to refund so i can call someone else. I just bought this house as my first home and money very tight.
1. Boiler comes on if i set Hive to 26C and will work fine (max it reaches temperature of 24 so always stays on).
2. As soon as i lower temperature to 22 for example, the boiler will power down but will never come back up to maintain target room temperature, it will keep dropping down to 17C (I'm at work from 6am to 6pm so watching Hive on the phone).
3. Fault 23 comes back on every time i lower the temperature - the boiler will fire up but will stay on only for half hour or so.
4. Pump makes plenty of crackling noise on occasion, gas engineer was sure its air in the system so all radiators has been bled and system refilled a few times.
5. Vaillant advised Fault 23 related to flow and return temperature, gas engineer says he adjusts flow and return every time he comes in but boiler still will not come on to maintain set target temperature.
6. For me to turn it back on i need to first close all the radiators expect for one closest to the boiler and let it heat, then i start to open other radiators, if i restart boiler after the fault with all the radiators open the boiler will not stay on and fault message returns after a few min.
7. Hot Water works absolutely fine, it turns on from Hive and heats up no problem, i hardy have it on as I'm on my own so just an hour daily or 3 hours during weekend days.
Please could someone help me figure this out, i can't take any more days off at work to keep getting the gas engineer in and every time he leaves same issue comes back. Any other details you need please just ask i will do my best to answer.
Thank you very much!
