Rated 1 out of 5 by from Horrible warranty service Our 15 month old washer broke 11/21 and we have been trying to get it fixed under warranty since there is a service bulletin out on the problem. There is a defective bolt that broke and did extensive damage to the washer. If LG would have spent a few cents on a washer for the bolt this never would have happened. We have been trying to get this fixed and customer service is horrible. At the moment we are waiting 7-10 business days for the resolution dept to come up with a decision. Don't buy LG! We posted on Nextdoor and are hearing many horror stories of it taking 4-6 months to get an appliance fixed.

Why was the LG WM3670HWA discontinued?

Asked by: Zoe22
The decision to discontinue the ENERGY STAR® Qualified LG 4.5 cu. ft. Ultra Large Capacity with Steam Technology, Model # WM3670HWA is a decision made at the Corporate level and there is a variety of reasons for why it is discontinued. It could be that a new product with newer standards and less expensive materials has been developed to replace the older product, or that components and materials for the older product are no longer available or available at cost-prohibitive prices. It could be due to declining sales for that product, or due to design upgrades. Regrettably, we are not privy to these decisions...^IFV

What dryers are compatible to stack with WM3670HWA? DLEX3370W is, however appears following are as well - DLEX3579W DLE3170W DLEX4370W DLX8100W. I am mechanically inclined so if DLE7200W or DLE71501W could work with minor mods, would like more options.

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
