Why is most of our loads taking over 2 hours to finish? Does this mean our washer needs repairs? We have had this washer for 2 years and have been having this problem for the last month now.

What are the rinse cycles 1, 2 & 3 used for?

Asked by: Seattlesas
Hello, sadly we are not understanding your question as the unit does not have 3 different rinse cycles. The unit has the option to add an additional rinse to the end of a cycle making it perform 2 rinses or perform a rinse & spin cycle only with washing clothing. If this does not help, please feel free to drop us a line on Twitter at @LGUSSupport or on Facebook at @LGUSSupport or just give us a call at 1-800-243-0000. ^AC

How long does each cycle take?

Asked by: JYSYE
There aren't any preset cycle times on the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity with Steam Technology, Model # WM3670HWA. Cycle time depends on the type and amount of your load and detergent, the incoming water pressure and chosen additional options. When you load your laundry into the washing machine, you can select the cycle that best suites the type of items to be washed. Each cycle has default options that are chosen automatically but can be modified. Some options will require more water and some will add additional time to the wash cycle for the best wash performance. The washer will show the estimated time for the selected wash cycle and when the start/pause button is pressed to begin the wash cycle, the washer automatically detects the wash load (weight) and optimizes the washing time based on the selected cycle and options. The display will then indicate the estimated time remaining for the selected wash cycle. Note that this is an estimated time and may vary from the actual time...^IFV
