AGA [n 3.11] fault codewhat it means and how to fix it

There is exactly one published sentence about AGA error codes, and this page is built on it rather than around it. Under the servicing and warranty heading, the eR7 and eR7i user guides say that in the unlikely event an error occurs, error codes may be displayed on your handset, for example: n 3.11, and ask you to provide AGA Service with that information because it will assist the service engineer in diagnosing your fault. Four things follow from those two lines and they are worth separating. First, AGA are not concealing the mechanism: they tell you plainly that the cooker generates codes and that you will be shown one. Second, the example they give is not really a code, it is a shape — a decimal-point number rather than the E-something or F-something that the rest of the market uses. Reading it as a group and an item within that group is the natural interpretation, but AGA nowhere say so, and we are not going to pretend they have. Third, the owner guides publish no meanings whatsoever: not a table, not a partial list, not one worked example of a number tied to a component.

The meanings do exist, in AGA’s own field service manual for the eR7, which is written for their engineers and organises the codes as three-digit numbers by fault type and zone; where this site carries one of those, as with 011, the page says so and cites the document, and how those three-digit codes relate to the n 3.11 form on the handset is not something AGA publish. Fourth, the owner remedy is the same for every code the cooker is capable of producing: read the number to AGA Service. So the honest answer to what n 3.11 means on an AGA is that the manufacturer has decided that question belongs to their own engineer. Anybody offering you a decoded list of AGA numbers that does not come from AGA’s service literature is guessing or has copied someone else’s guess, and we will not publish one either. What is genuinely useful is knowing that the number matters and that it is perishable. Write it down exactly as it appears, digits, space and decimal point, before anybody switches the cooker off, because an engineer arriving at a cooker that has since been power-cycled has lost the only diagnostic AGA gave you.

One structural detail deserves its own attention. The owner guides say the code may be displayed on the handset, and the handset is a battery-powered remote, so an owner who has mislaid it, or whose batteries have gone flat, has lost the place AGA tell them to look. The cooker is not entirely mute: the eR7 has a control panel behind the top left hand door with LED indicators and a character display, and AGA’s service manual says most faults show there as the zone lights flashing rapidly, while the panel display itself carries only three codes of its own, FE, VE and CE, about the panel and its connection to the main board. But a flashing light tells an engineer far less than the number does, and the guide also says a damaged or lost handset can be replaced by AGA and re-programmed to the appliance. That makes fresh batteries and a known home for the handset a diagnostic precaution rather than housekeeping.
