I own a Samsung DV22N6800HW/A2 4.0 CF Heat Pump Dryer. The condensate pump in the bottom tank comes on too frequently and when there is no water to pump out the noise it makes is extremely annoying to everyone in the house. There are time when the dryer works for several loads without issue. Other times it back to screeching as it pumps without water. Pump replaced, float replaced. When I am reset the dryer a while back do to a water tank error , i ended up having to replace the main board. No matter the cycle, light loads, air refresh or towels, same screeching noise.
