Think the missus took that strainer thing off to clean whilst the cleaning program was going... I think MoH is right, poke her behind the thing to get it sorted. Might try the bi-carb and vinegar first though, cheers.
Whats this cleaning program? I need to have a chat with her....I clean my dishwasher myself (for something that cleans they get awfully gungy) - take all the filters out and flush it through manually (ooh err) but I haven't heard of one of these does it for you jobbies?
