What S
actually means.
On an eR7, an S in the roasting and baking oven windows means you have put the cooker into slumber mode, where those ovens sit at a reduced heat instead of a cooking setting. It is chosen with the M button and uses less energy between meals.

What to do when S shows on the stoveKind of codeMode, not a failure
Something the stove was switched into, often by accident, rather than something that broke: a control lock pressed while wiping the panel, a Sabbath setting, a showroom demo mode that lights the display and heats nothing, a reminder that a spot on the stovetop is still hot. No part is worn out, and the stove's own keys put it right.

To cook, press the symbol for the oven you want and it moves from slumber to a cooking setting.

Before you book,
in this order.
Each step comes from AGA's own guidance for S on its stoves. Follow it to the end: the last card says whether this is a visit.
To cook, press the symbol for the oven you want and it moves from slumber to a cooking setting.
To leave slumber for the whole cooker, press and hold M for 3 seconds.
Wait until the oven symbols stop blinking, which means the chosen heat has been reached.
Cleared?
The stove is working again and no part was needed. If the same letters come back while a burner or the oven is on, or the stove switches itself off again in the middle of dinner, book it as a new problem.
What not to do
S is not a warning and nothing has failed. An oven that feels only warm while S shows is doing exactly what slumber mode asks of it.
What you may
notice with it.
