Glow-worm Micron, Ultimate FF/BF/CF, Hideaway, Space Saver, Swiftflow, Energysaver, Fuelsaver fault codes

No code system. The Space Saver KFB and Ultimate FF have four neons that light in sequence — mains, thermostat, air flow, ignition — and their manuals call them "an aid to fault finding only"; the Micron has a reset neon cleared from the control knob; the Swiftflow a red neon on its safety cut-off reset button. Their manuals were read for this pass, except the Fuelsaver Mk2, whose only copy is a scan without a text layer, and there is nothing to search for on any of them.

Codes on the Micron, Ultimate FF/BF/CF, Hideaway, Space Saver, Swiftflow, Energysaver, Fuelsaver follow the same Glow-worm scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.
