Hoover HBWD 7514DA-80 Fault E21

Sometimes an error code is displayed that according to technical information is, "not used". How that is possible is not clear, but it is possible that the error code is not supposed to be in use. The only other explanation is that they just don't want to tell you what it means. Once it is known what an error code means there is an avenue open for investigation. Manufacturers always justify this by saying they do not want to encourage people who don't know what they are doing to mess about with dangerous repairs. They definitely have a point there.

Unfortunately error codes give a lot of control to the manufacturers and many error codes are deliberately kept secret, sometimes even from qualified independent appliance engineers. The other side of the coin though is that before error codes washing machines used to commonly flood people's kitchens, boil people's laundry, and go crazy jumping about and smashing up the kitchen. So the ability for a washing machine to detect an error and shut the washing machine down is a wonderful advancement. Just not so much keeping the code secret :-)

Andy thank you. My thoughts exactly, I contacted hoover and they couldn't provide any technical info on this code and emphasised that only a hoover engineer could repair this specific issue... According to their script.
