What People Are Saying

Rated 2 out of 5 by from Can't wash without water I bought this about a year ago and I can see why people do not like front load washers. I am in the commercial laundry equipment business and do not understand why manufacturers are not able to take cues from their commercial lines. Brand does not matter. Soap needs to mix with water to wash something. It helps to flush out any soil you can prior to the wash bath. My clothes are not even wet before the soap is dispensed. Add a warm or cold flush before the hot or warm wash bath. Make sure the water level is high enough to touch whatever you are washing. It will help. Energy star is great but it wont matter how much water you save per load if you need to wash something 3 times.

Rated 5 out of 5 by from Great Washer Bought this a couple months ago to replace my older LG washer that we had for over 10 years

Rated 5 out of 5 by from Just as Expected! This is our second LG washer and we are once again pleased with our purchase. Many nice features but the overall rating speaks to how well the washer cleans all types of laundry. The duration of the washing cycle is also less than anticipated which is an added plus; conserving both energy and time. We love the stainless steel face because our W/D resides in an open area in our Master Bathroom (condo). It is certainly attractive enough and hiding the unit behind a door would almost seem unfair.

Rated 5 out of 5 by from Great washing machine I almost didn’t buy this machine do to the negative reviews. I’m so glad I didn’t let those reviews sway me away from buying this washer. I love having all the different cycles to choose from very pleased with the performance everything comes out clean . One note that is important make sure the delivery guys level the washer and run a quick wash to make sure machine doesn’t have any damage from shipping. Other than that great machine .

Approximately 6yo machine. Recently there's a grinding noise when water comes out of thd jet spray nozzle. Nozzle is not clogged. Washer spins and drains fine, pump filter clean, clothes come out clean, machine is level, no error messages. Any ideas?

Asked by: Valoha
Typically, our washing machines are very quiet all throughout its operations. Are the water lines fully open when in use? Please contact our Customer Interactive Center at 800-243-0000 to troubleshoot this matter.
