Rated 4 out of 5 by from Rust is Ruining My Clothes Great machine. I learned to live with the balance issues. But the rust on the top cover is ruining my clothes. I’m trying to find someone to replace the top cover.

Rated 1 out of 5 by from Terrible! Not using their "example" for sure. So we have owned this for a few years now and are having the same problem many others are having with balancing. Brand new it worked well, but after 40-50 loads it started to have balancing issues. Initially I blamed it on a towel or jeans in the load (though a clothes washer should be able to wash those as well) but now has gotten so bad that the drum will slam the sides of the cabinet with an empty load then show the all too familiar unbalanced load code. This is one where if you like to babysit your washer, shift the clothes around, watch it fill, try to spin, then fill again, shift the drum, try to spin, fill again, try again, then code and repeat for 3 hours, then this is the washer for you! I personally have other things that I need to get done. I have an old washboard and find it to be faster and less work to fill a washbasin with borax and start scrubbing than let this machine try to unbalance itself for the 47th time (not to mention the water useage of filling and draining each time. So the problem is they designed this washer with the isolation struts connecting to the bottom of the drum. Well the water and weighty wet clothing is at a much higher center of gravity than the isolation points, thereby making an unbalanced load extremely easy. Terrible design that can be fixed by a savvy person with free time and adding springs to the top of the drum to assist in the isolation.

Can I use detergent pods in washer?  Do I put them in the washer or dispenser?

You can use High-Efficiency detergent pods with the ENERGY STAR® Qualified LG 4.7 cu. ft. Ultra Large Capacity High-Efficiency Top Load Washer with WaveForce™, Model # WT5170HW. The pods have to be placed in the tub before adding your laundry. Do not add them to the dispenser...^IFV

My slam proof lid doesn't shut softly anymore, so if unsupported, will slam shut on its own. What needs to be replaced to bring back this function? Hopefully not the entire lid?

What's the max number of gallons of water this washer will cycle thru for 1 load 

Asked by: Unclebrocstar
Regrettably, there is no way of determining how much water the ENERGY STAR® Qualified LG 4.7 cu. ft. Ultra Large Capacity High Efficiency Top Load Washer with WaveForce™, Model # WT5170HW will use for any given cycle because they are several factors that will determine how much water it uses. This washer automatically adjusts the water level by taking variables such as cycle selected, the load size, the load weight, fabric type, fabric thickness, amount of suds, water temperature and more to determine how much water to use. Some cycles require more water as will some added options. If the washer detects excessive suds, it will activate the Auto Suds Removal feature and the unit will drain and add water to dilute the concentration of detergent and it is possible for this feature to be activated multiple times within the same wash cycle...^IFV

If I use the hot water button why am I still getting cold water in machine 

Asked by: Ret155
We regret the inconvenience you have experienced with this washing machine. If the COLD water is all that is received when the HOT cycle is active, then it would be recommended to check the water lines to make sure they have not been installed backward, as this is the primary cause for such a symptom.

The machine has stopped playing the melody when the clothes are done. What could have happened?

Asked by: Sharronie
We regret the trouble you have experienced with this washing machine. Check to see if the SIGNAL function has been deactivated. Press the SIGNAL button another time to see if it switches this feature from the OFF to the HIGH position. Information about this option can be found on page 26 of the owner’s manual.
