The grill, base and circular elements are the components that actually heat your oven up.
Are you finding that the grill mode on your oven isn't effective, i.e. that it isn't working properly? Are you also finding that your food isn't cooking properly and that the oven isn't heating up well, or even not heating at all? One or more of the elements could be causing this.
