I can't really answer your questions. .but I have a Duet and there are no bursts like the LG...also I highly doubt you will find a FL today that adds burs ts of water than finishes with pourin g in water for several minutes, I suspect with your LG being as old as it is it uses a whole lot more water than what's on todays market..someone will be along to help you with your issues..but usually hammer problems are there from the beginning not 9 years later...but what do I know LOL...

I have a 2 year old LG built for sears the large 5.2 cubic ft 41072. it fills with two bursts of water and then fills for the load size. I've never had the water hammer issue, but believe the hammer is related to the type and age of the pipes in the building. My previous machine was a whirlpool duet that never had a hammer issue (same house) and died after 9.5 years from a fried computer board. That duet didn't fill with bursts at all; the water just filled .

As noted above, the average life of current machines is about ten years depending on usage. Yours is approaching the point where things start to happen. Water hammers issues happen immediately if you're going to have them. Your machine uses much more water than mine. Have you always had multiple fill bursts or is this New?

I would check your regular laundry load size before getting a much larger machine . do you regularly wash very large loads, pet beds, or king size Quilts? It may not be worth the extra cost of the larger machines if you only use the full capacity once in a while.

I like my big machine, but I regularly wash ten yards of fabric. we wouldn't need something this big if I didn't sew and quilt. many of the big machines have problems doing small loads. any machine you consider should have an on board heater if you want a true hot wash. water temperatures are now controlled by automatic temperature controls by the machine irrespective of what your hot water heater is set. They also won't tell what temperature "hot" is. my machine has a hot setting of about 115F. Just warm in my opinion. I regularly use the steam function to up the water temperature to 140F. use of this function also increases wash times to 2 hours for the cycle. yes, there are trade offs.

If you can't fix your machine, good hunting.

LG is the only brand I know of experiencing water hammer. Have the 5.2 Kenmore as Poppy does for a year and 8 months. Excellent machine and I would buy again. If I were in the market my top two picks are the new Electrolux and LG. Both still offer real Sanitize heating function wirh LG having the most flexibility. In the higher price point category, Miele hands down!

No issue with the compact electrolux...

LG is a big offender in the water hammer department. You will most likely need to have a plumber come out and possibly replace or install an expansion tank for the whole house.

I've never had a water hammer problem with any of my washing machines. Had a good old TL Maytag for many years and have since had two Frigidaire FLs, one WP Duet FL (Kenmore branded) and one Samsung FL. Actually have never had any kind of problem with any of them other than the Maytag finally died. The others are either going strong now in one of my houses or were going strong when I moved and left them behind.

Hey guys/gals,

Thanks for the feedback. Sounds like the Whirlpool just fills. Sounds like the Electrolux does the same with a couple of short adjustments once the clothes starting absorbing water? I hope I got those correct?

Yes, the machines are getting up there in age as poppy214 suggested. I started noticing problems a few months back. When the washing machine was on, I started hearing a "psssst" (not sure how else to describe it) outside. After I heard it a couple times I went outside, and I could see and hear a mist being pushed/sprayed out of the vacuum breaker on a hose bib (faucet) outside. I was thinking....."what the heck is that?". Then it did it a couple more times, etc...and I realized it was happening when the washing machine was going through the initial short bursts of dumping water in.

Granted, it only shoots out of the vacuum breaker if you have the hose bib "on", with let's say a hose attached to it and then a water nozzle on the hose, since the hose bib has to be on for the water to reach the vacuum breaker, if that makes sense.

As time went on, I noticed it more and more and even out of a couple different hose bibs. That's when I went and picked up a couple of the "mini-arrestors" and installed them on the washing machine valves. That did not help a thing, or if it did, it is not noticeable. I doubt that water mist shooting out of the hose bibs is normal...but I'm not sure. The house pressure is only about 50 psi after the pressure reducing valve, so that's not too much. It's about 90-105 coming in before that. I could reduce it further, but I don't believe I should have to...maybe it's worth an experiment...however that also means it reduces pressure in the showers, etc.

The problem has slowly gotten worse, so now I'm thinking maybe somewhere a pipe has come a bit loose and that's now the water hammer I'm hearing. The good thing is I can hear it in a couple spots which are more accessible, so that's easier to address if I have to open something up. Like I said earlier, I'm thinking about the next size up water hammer arrestor to install on the main supply lines, not just on the washing machine valves. I'll look into it more this weekend.

The funny thing is that....if I only do a "Rinse and Spin" cycle, the machine just fills up one time, no short bursts, and I don't hear any noise or if it's there, I am not hearing it like I do when the short bursts of water happen.

On the next load of laundry tonight, I will count the bursts before it starts filling.

Thanks again for the help.

I was thinking I read somewhere on this site that a guy had the same problem but fixed it by installing new fill hoses in a larger size. I really thought they were all the same but best I remember he even gave the size and maybe where he bought them. Might do a search and find that post.

Yes, LG front loaders are the only washers, to my knowledge, that do these little bursts of water. Not sure why - maybe to "blast" detergent out of the dispenser? I don't know. All other washers will fill in a more steady fashion. However, all front loaders will fill several times, at least for the first fill (main wash), depending on how large and absorbent the load is.

@whirlpool - I have never been able to figure out the rationale behind the goofy fill pattern. I think its just the way its programmed.

I have the Miele PW6065 Plus (Little Giant). It is considerably smaller than what you have or what you (think ;) you need. Besides from thick comforters, my "small" Miele will handle anything and everything your much larger unit will do, and the Miele will do it better, faster and care for whatever you are washing best!

I used to only have BIG machines, and they can be great when washing something BIG, but for our household of 3...most things washed are clothes, sheets and towels. The Miele Little Giant however easily washes our CA King blanket (not thick, not thin).

I cannot express how happy I am having a "smaller" (but big for most of the world) washer!!

I have an LG FL that is about 2 years old. The house is about 10 years old, and water hammer was a big problem. My washer fills in the same manner you described; several short bursts, followed by a few longer fills. I purchased and installed two resters sold on Amazon, Sioux Chief Mini Rester and the problem was solved. I have heard that you may need to replace the resters every few years. Sounds like you have tried this, but I just wanted to add my success story, in case you had used a different brand or type.

Thanks to everyone for the comments. I wanted to give a little update on the filling patterns of my machine. I did a couple loads of laundry on Saturday and wrote down my observations. I did not time them with a stopwatch...I just did the old "one one thousand.....two one thousand....three one thousand...." approach like we did when we were kids... while I jotted down how many times and for roughly how long. A stopwatch would have gotten in the way during all the short bursts.

I loaded my machine....and after it auto sensed the load size, it sensed it as a full load (4 out of 4 bars), so it should have used the most amount of water I guess. I used the following options....pre-wash... extra rinse....and water plus. Here's how the machine filled.

During the "pre-wash" stage, I observed the following water filling bursts:

- 12 short bursts of water, roughly 1 second each, maybe 3 or 4 seconds apart.....+/-

- 1 long burst of water, roughly 30 seconds.

- 2 medium bursts of water, roughly 7 seconds each.

- 1 long burst of water, roughly 30 seconds.

- 4 medium bursts of water, roughly 4 seconds each.

- 1 long burst of water, roughly 35 seconds.

So 21 separate bursts of water for the pre-wash stage.

During the "main wash", stage, I observed the following:

- 6 shorts bursts of water, roughly 1 second each

- 1 long burst of water, roughly 30 seconds.

- 5 short bursts of water, roughly 1 second each

- 1 long burst of water, roughly 20 seconds

- 4 medium bursts of water, roughly 4 seconds

- 1 long burst of water, roughly 30 seconds.

So 18 separate bursts of water for the main wash stage.

For the "rinse" cycles, I did not count and/or time, however it was something like:

- 1 long burst of water for maybe a minute, again I did not time it...it just fills...

- 1 or 2 short to medium bursts...again, I did not time these

I just wanted to give you guys an update, and see if anyone has water fill patterns like these or if these are completely ridiculous...which I think they are. Again, the machine is 9-10 years old....so it's time to start looking for a new one....this is driving me crazy. Someone asked if this was a new thing or if the machine always did this. To be honest....I didn't pay attention to fill patterns before I started having the hammer issues and water/mist shooting out of the exterior hose bib vacuum breakers awhile back.......so I cannot say for sure. Now I wish I had paid attention to it from the first day years back..

I was watching some LG videos on YouTube and, while your LG has an older software on it, these mini-fills are still being used - although not as excessively as your LG does.

It's a LG thing and has been for years Mine does it. I installed the arrestors and it took care of about 90% of it. They act like it's not a problem and blame it on the plumbing. Funny no other washer brand has this issue. Otherwise, I've had zero issues with it and it does a good job

Never had any water hammer issues with my Samsung and neither has my daughter, I know this because I help out with her laundry... ugg....

LG is being sued about the water hammer problem. The short bursts are to spray the clothes with water at the beginning of the cycle in order to dampen them quickly. This causes the valves controlling water flow to open and close very quickly. When a valve is shut in less than a second while water is flowing, it creates a huge pressure spike backward into the pipe. This weakens the solder in the plumbing over the entire house and if left untreated will eventually result in leaks and possibly void the warranties of other appliances and hardware connected to the water lines since all of them, even faucets, have pressure limitations. The solution for LG designers was to use what is called a soft close solenoid which is marginally more expensive than a fast close solenoid. But LG decided to ruin their customers' plumbing rather than to use a quality part designed for this application. LG also makes Kenmore washers however it seems Kenmore (Sears) required the soft close solenoid on the washers made by LG under their brand. Consumer Reports still give LG high marks and fails to alert consumers about the problems with water hammer which has led me to distrust anything CR says. As a result of the many water hammer problems, LG not only failed to fix the problem but instead added a rider to its warranty to expressly exclude water hammer from its warranty coverage. We had a leak as a result of water hammer even though we had high quality Watts water hammer arrestors (not restors as stated above) in place. My advice is to avoid all LG washers in order to protect your plumbing. LG is also being sued about the ice makers in their refrigerators. Not a reputable company. Caveat emptor is a phrase invented specifically for companies like LG.

I have a 4 month old LG washer and have no water hammer issues at all. My warranty has no rider to exclude water hammer from its coverage. I love my LG washer It uses plenty of water using the water plus option. Are all LG washers known for having water hammers or just certain models?

I think the Miele PW6065 is 7 KG ~ 3.5 CF and they are EVERYWHERE in laundromats throughout Europe.

Has the issues been fixed in newest models? Have they started using a different valve technology that closes softer? can't find any information anywhere and LG reps are largely useless for engineering questions. Looking at the newer models WM3770HVA or WM3700HVA. Please advise.

I have a SAMSUNG compact washer WW25B6800.

Quite disappointing: Lots of loud water hammers. Many many shorts water bursts during the rince cycle instead of one long filling step (even worse if you choose Extra rinse). I thought that my plumbing would explode! I had a plumber come in and install water hammer dampers on the appliance. Better, but far from perfect. I don't recommend that model - nor that company, for that matter.
