Looking for Answers about samsung 4.5 cu. ft. King-size Capacity, Touch Screen LCD Front-Load Washer (Onyx)?

I've noticed that when I run a Heavy Duty cycle, the estimated cycle time is around 1 hour 45 minutes, but then it changes to over 3 hours as the cycle runs. Is this normal? Do I need to request service?

I didn't know how to follow up to the posted answer, so I'm just creating a new post. Thanks for your response. I understand that a spin imbalance can extend cycle times, but my washer is exhibiting this behavior very early in the wash cycle, before the first spin even occurs.

For some reason both the washer and dryer....at the same time take way too much time to power up. I press the power button and nothing happens. Hit it a few more times and it will eventually power up. Once it gets going all is well.
