    The Cause
    The heater core was blocked with contamination which led to poor heater performance. The contamination was caused by a faulty water softener within the factory, which supplied the coolant filling machine with water contaminated with chloride. This results in a level of internal surface corrosion developing in the cooling system. The resulting corrosion blocks the heater core.

    Countermeasure at factory (Swindon)
    A reverse Osmosis unit has been fitted after the water softener process. In addition, conductivity sensors have been fitted which will detect a rise in chloride and shut off the water supply should equipment failure occur.

    Looks like honda is keeping me busy! Have to take the dash out complete to replace the heater core. Hoping the majority just need a flush.
