I purchased the set to fit in a small space. Dryer will only dry for 2 minutes before shutting off due to “clean filter”. I clean the filter every time and there is little to no lint. Why does this happen? I can’t get 1 load to dry in a day? Towels are the hardest to try dry, the sensor doesn’t work either as they are always still really damp. Not pleased with the performance based on price paid for the set.
