WM3477HW (new version of LG WM3455HW)

by Jaro

RANK #1:

LG washer dryer combos have a really great name in this industry and this model represents it very well. As you can see, I actually ranked it #1 because it has the best features, reliability (according to users who shared their experiences all over the internet) and still not expensive. The features and technical details are exactly the same as with LG WM3477HS. The only difference is the color – the last letter W in the model name WM3477HW stands for white.

This is the new version of my previously #1 ranked WM3455HW and it proved to be a reliable successor. All the details and features are the same. The only difference is that WM3477HW  has one drying cycle less than the older model.

Pros and Cons:
  • Well-designed unit with a stylish and luxury look.
  • Great performance, features and energy efficiency – saves money on your electric bill.
  • Easy to install, easy to use.
  • It’s very quiet. Should be mounted on a solid flat floor or vibration isolation pads to solve any vibration issues.
  • Excellent capacity for the overall size of the machine. Just to compare, it washes the same amount of clothes as the typical smaller commercial machine you find at a New York City laundromat.
  • If half loaded, it takes just 1 hour for clothes to wash and dry and just 1.5 hour for jackets and heavy wool items.
  • The clothes that come out feel great. They are soft without using fabric softener and clean with a minimum of soap.
  • It’s ventless and uses condensation to make the vapor release its moisture and be pumped out along with cold water used for this purpose.
  • Uses very little water (70% less water).
  • You can interrupt the program at any time, change any setting or open the door, and then resume.
  • No negatives other than the common ones below.
Negatives common to all combos:
  • There is no exterior lint trap for the dryer. The lint tends to collect around the rubber seal and you have to empty that once a month depending on the frequency of use.
  • The clothes need to be free to tumble in order to dry completely. Fill only half of the drum if you’re going to use the dry function.
  • Noisy water pump that expels the water from the machine – although active only intermittently during the wash and rinse cycle.
  • Produces a bit of heat.

    Does this unit require a hot water connection or does it heat the water on it’s own?

      Hi Myrna,

      you’ll probably wanna need the hot water connection as well. Although this unit has a 1000 W internal water heater, only its “Sanitary cycle” option can use it to heat cold water for the load you wash. It’s a NSF-certified feature that heats water up to 158 degree Fahrenheit to remove even the toughest stains and bacteria. It also saves energy it reduces your need to utilize hot water.

    I just got a great deal on an almost new one for sale on Craigslist and they delivered it to me from a town two hours away. The seller only used it twice and needed a bigger machine. My question is is it okay to put this on wheels with brakes?
