This week we replaced the fluff filter and now the flashing lights do not occur at the end of a drying cycle. Previously they always flashed at the end of a cycle when a wet load of clothes were being dried.
It seems me to be quite strange that even though something is being deliberately signaled with the flashing lights, no means of interpretation has been made available. It would surely be quite simple to have a list of error conditions along with a list of how they are displayed.
