Why this softener earns its place
FB151 is the 12 litre Classeq WS12-SK base exchange external water softener. The verified manufacturer description states that it is suitable for cold-fill water up to 35°C, so the first site check is the feed temperature rather than the dishwasher model.
The casing is stainless steel with a silver finish. Its listed dimensions are 520mm high by 180mm wide, giving it the same narrow width as the 8 litre and 16 litre Classeq softeners while sitting between them on height and gross weight.
At 15kg gross, it needs a stable service position with access for installation and routine checks. Published data here does not confirm hourly output, resin capacity, regeneration method, salt type, power requirement or compatible machine list, so those claims should not be made from this file alone.
