New Vokera boiler faulty

[Aqibra]

I’ve just got a Vokera Easi-plus 29 boiler installed yesterday by gas safe registered engineers. The boiler is brand new. However I don’t get hot water. The radiators are working fine. When I open the tap, warm water comes for a few seconds and then it goes cold and the solid green light on the boiler starts flashing. The gas engineer said this is a fault with the boiler and told me to contact Vokera. Any advice would be appreciated on what the problem could be. Thanks
