Potterton Suprima

[GSO]

Have a Potterton Suprima less than five years old. Has been fine until the last couple of days but now the hot water comes on but no heating. The gas lights okay for the hot water but not the heating and when I press reset the green light does not stay on.

Does anyone know what this could be?

Thanks.
