Rated 5 out of 5 by from Clean clothes Very good cleaning performance. Washer is fairly quiet and has enough features to satisfy average user. It required installations of additional mini arrestors on inlet valves to prevent water pulsations noise during the fill event, my house water pressure is high.

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

Which front load models have a 75 minute wash cycle 

Asked by: Kmkm
Hi Kmkm. Unlike older washing machines that had a set time for how long certain cycles ran, the cycle times for our washing machines will vary. LG washers take variables such as cycle selected, the load size, load weight, fabric type, fabric thickness, amount of suds, the water temperature and more into account. These variables may extend cycle duration as they may require more water, take more time to absorb the water or take longer to drain and spin. The required water pressure for our washing machines is between 14.5 PSI and 116 PSI. If the water pressure to the unit is at the lower end of this range, it will take longer for the unit to fill which adds to the cycle time. Some added options like the WATER PLUS option extend the fill time since this option adds additional water to the cycle and that too, extends the cycle time. The STAIN cycle option will add time to the wash cycle to enhance wash performance and the STAN CARE option adds time because it needs to heat the water to different temperatures according to the stain selected for an enhanced stain removal. The wash and rinse optimizer add time by extending the wash cycle if there is not enough detergent for the cycle and will add time to the rinse cycle if there is too much detergent. There is the AUTO SUDS REMOVAL feature which activates if the washer detects excessive suds in the unit. If it is automatically added without selecting any option, the washer will drain and add water to dilute the concentration of the detergent. This feature can be activated multiple times within the same wash cycle and each activation adds approximately 12 minutes to the wash cycle. If you select the Cold Wash™ option, wash time will be increased up to ten minutes...^IFV

We want the WM3670HWA + stack an electric ventless dryer on top of it. Can you advise what LG dryers are ventless electric that we can stack on top of the WM3670HWA? Also, what stacking kits do we need? Will we need to buy extra power cord or hoses?

Does the door lock? I don’t want a child to be able to pull it open while it is running. 

Asked by: FTSH
The ENERGY STAR® Most Efficient 2018 LG 4.5 cu. ft. Ultra Large Capacity with Steam Technology, Model # WM3670HVA does have a 'Child Lock' that can be activated by pressing holding down the Pre Wash/Child Lock button on the control panel for three seconds. Child lock will remain active even after the cycle ends and you will need to deactivate it the next time you turn the machine on to do your laundry. However, the Child Lock feature does not physically lock the door, it prevents a child from tampering with the controls. The door on the washer automatically locks when the wash cycle begins and will unlock when the cycle ends. If the temperature or the water level inside the machine is too high, the door cannot be opened and to open it while washing, you would need to use the Rinse + Spin feature...^IFV
