The washer and drier work great and efficiently. I like the dryer features that I can adjust the time from 20 minutes with 10 minutes intervals to 60 minutes or use automatic sensor to dry.  One time the washer run a whole cycle but did not release water. I had the machine serviced and the service person said that I put too much soap and this may cause this problem. Nowadays laundry detergents are normally concentrated. I only need 1 tablespoon of detergent to wash half load of cloth. With a full load, 2 Tablespoon is enough. The machine sensor release the right amount of water to wash the cloth and too much soap for too long can cause the problem. I am glad to learn this lesson or I will continue to put too much soap every time I wash clothing.
