My machine shakes violently during the spin cycle

I recently purchased the washer/dryer for my new home in Queretaro Mexico. during the installation I ensured that all feet were well adjusted and the machine is level. Although when it goes into the spin cycle it shakes violently, moving all around and banging the walls. I really need someone to come to my home and fix properly. I think something is wrong on the inside, I have had the machine 4 weeks, purchased from SAMS.

Answer: 
LG Advocate is correct see Installation Instructions in Manual under Unpacking for images:
IMPORTANT: To prevent internal damage
during transport, the washer is equipped with
4 shipping bolts and plastic retainers. These
bolts and retainers MUST be removed before
operating the washer.
• Failure to remove shipping bolts and retainers
may cause severe vibration and noise, which can
lead to permanent damage to the washer. The
cord is secured to the back of the washer with
a shipping bolt to help prevent operation with
shipping bolts in place.

Answer: 
Check that the "packaging support" material has been removed from the underside of the unit. As shown below, the packing support piece sits on the base packing piece and the washing machine sits on top. The packing support piece fits up into the machine and nestles against the bottom of the tub. If this is not removed, vibration will occur. It is white and made of foam.

Check that all four shipping bolts have been removed. These bolts, as shown below, screw through the back of the unit and into the back of the outer tub. This secures the tub during transit, so it does not bounce around and damage internal parts. If these bolts are not removed, the unit will vibrate, even "walk" across the floor.

If the unit is mounted on a pedestal, check that all four pedestal brackets are attached. There should be two on each side. The brackets attach to the pedestal with two screws each and to the unit with a very strong adhesive. Remove the screws from the pedestal brackets. If the brackets come off, check to see if the paper over the adhesive is removed (if not, remove it). Reattach the brackets and press firmly on the top of the bracket to adhere the brackets to the washer. Rub back and forth, firmly.
Washing Machine
Vibrations
For new installations, check the following:

1. Check that the "packaging support" material has been removed from the underside of the unit. As shown below, the packing support piece sits on the base packing piece and the washing machine sits on top. The packing support piece fits up into the machine and nestles against the bottom of the tub. If this is not removed, vibration will occur. It is white and made of foam.

2. Check that all four shipping bolts have been removed. These bolts, as shown below, screw through the back of the unit and into the back of the outer tub. This secures the tub during transit, so it does not bounce around and damage internal parts. If these bolts are not removed, the unit will vibrate, even "walk" across the floor.

3. If the unit is mounted on a pedestal, check that all four pedestal brackets are attached. There should be two on each side. The brackets attach to the pedestal with two screws each and to the unit with a very strong adhesive. Remove the screws from the pedestal brackets. If the brackets come off, check to see if the paper over the adhesive is removed (if not, remove it). Reattach the brackets and press firmly on the top of the bracket to adhere the brackets to the washer. Rub back and forth, firmly.

For all, check the following:

1. Vibrations only occur on some, but not all loads.

If this only happens on some loads, it could the load type rather than the washer.

Check if the load is small or large, consists of mixed fabric types (such as jeans and t-shirts), or is a large item (sheets, blankets, etc.)

Items in the drum may not distribute evenly across the surface of the drum which can cause vibrations. If this seems to be the case, pause the cycle and move the clothes around and restart. It may be necessary to use a lower spin speed to minimize this.

If your unit has the SpinSense Feature, activate it. This will allow the unit to detect vibrations in the unit sooner and accommodate for them.

2. Are the clearance requirements at the sides, back and top met?

The unit requires one inch clearance on top, one inch at the sides (in addition to requirements of a companion appliance), and four inches at the back. If clearance requirements are not met, vibrations can result.

3. Check for foreign objects under the feet of the unit. If there is anything under any of the feet, this will prevent the unit from being properly leveled. Vibrations and slipping may occur. If an object (such as cardboard or wood) is under the foot because the unit is not level, then the foreign object should be removed and the unit leveled.

4. Make sure that the unit is leveled. When the unit is in a spin cycle, make very slight adjustments to the feet. Even a quarter of a turn can stop the unit from vibrating.

CAn I use a tankless hot water heater with this?

We need to replace our current water heater and would like to go with an electrical tankless model. Can the LG WM3455HW be used with a tankless heater and if so, do you recommend a specific brand?

Answer: 
I have a Noritz tankless and absolutely love it!!! You can set the temperature to 120 easily. Noritz has a range of temps to set the heater to from 100 to 140, so you can get a constant temperature as the expert recommends.

Answer: 
In order to have proper HOT and EXTRA HOT water operation, the inbound water temperature needs to be at least 120 degrees. Using a tankless water system typically would not be able to provide a constant temperature level. Having one can potentially effect the washing capability of this unit.

Answer: 
I installed mine under my kitchen counter - it fit and looks great, although we had to cut away the linoleum directly beneath it - but you can't see the floor beneath the unit anyway. And the unit protrudes from the edge of the counter about 2 1/2" but still looks snug.

Answer: 
Hello Susan,

The Dimensions of this model are (WxHxD) 24” x 33 1/2” x 25 1/4” plus Clearances 1" at the sides and 4" behind the unit... which means you would need a pretty deep counter top.

Thank you. We appreciate your feedback, please give us a “thumbs up” if this answer is helpful to you; and please let us know if we can assist you with anything else.

Have a lovely weekend!

Answer: 
If by "backflow" you mean siphoning water back into the machine from the drain hose: my unit allowed backflow when I made the mistake of hard sealing the drain hose to the 2" pvc drain pipe.

Answer: 
Yes, it does have a check valve that would work as a preventer - this is true for all of our washers.

Once it has finished the drying cycle, are you supposed to clean lint from it like a standard dryer? If so, where do you clean the lint from?

Answer: 
i have read that after a period of time, lint builds up in the bowels of the machine that requires taking apart the machine either by a tech or you if you are that handy. as stated, the only lint trap is the water trap. i wanted to create one in order to avoid having to call a repair man to declog the machine. i placed a 1 cm diameter fibroglass screen double folded over the small hole at 6 o'clock. i have noticed that it traps alot of lint and dog hair. since then, i have been regularly checking the water trap and have min if anything collecting. before, it would be full after 3 to 4 washings and dryings. the water drains well and have not had any alarms set off. interestingly, my wash is dried in one hour. any other suggestions?

Answer: 
Cleaning the Drain pump Filter
Lint and other objects may accumulate and clog
the drain pump filter. If the washer fails to drain
properly, unplug the washer and allow the water
to cool, if necessary, before proceeding.
Open the drain pump filter access panel.
Unclip the drain hose and pull it out.
Place the end of the drain hose in a pan,
bucket, or floor drain to catch the water.
Remove the plug from the drain hose, and
allow the water to drain completely.
Twist the pump filter counterclockwise to
remove. Remove any lint and foreign objects
from the pump filter.
Reverse the above steps to reinstall the drain
pump filter and drain hose. Be sure to close
the cover panel when finished.
