Beko WTE 5511 B0 Washer: Reoccurring Rotten Egg Odor from Water Inlet Hose After Replacement

Hello, I am trying to solve the mystery of the bad smell. My washer is a Beko WTE 5511 B0. The rotten egg smell only comes when the washing machine starts drawing water. When you start it, it draws about 1 liter or something of water which stinks. After drawing the water, it is fine. I had this problem and decided to replace the intake hose because the smell was coming only from the hose itself, not in the pipes which are under the sink in the kitchen (kitchen faucet water does not smell bad at all and the pipe which supplies the water is the same pipe for the faucet and washing machine and dishwasher). So replacing the hose helped only for about 3 months or something. After replacing the inlet hose, I was so happy because the rotten egg smell was finally gone and it made sense, neither the main cold water pipe smells nor faucet water. Today, the smell has returned. It doesn't make any sense. I checked everything under the sink again. I unscrewed the 3/4 hoses for both the dishwasher and washing machine, and nothing stinks, neither from the hose nor from the tee valves. I ran a little bit of water from the unscrewed 3/4 part from the tee valve and the water is fine, which makes sense as I said the water from the faucet is good. So I'm sure the problem is not under the sink. Also, today I tried to check not the part under the sink where the dishwasher in this case connects, but I checked the part where the dishwasher connects in the machine itself. I ran some water there with the unscrewed hose and it doesn't have a rotten egg smell. But when I started the washing machine, the rotten smell instantly appeared when it started to draw the water. You can open the drawer where you put powder, it stinks so much, but only for 30-60 seconds after it draws that rotten water. There is no issue with the drain hoses, I literally disconnected them, and they actually smell nice like washed clothes. It's not an issue with the draining system at all, neither the filter that is on the bottom of the washing machine smells. The smell only generates in the hose overnight. So, in a simple way, the smell only occurs when you don't use the washing machine for a day, then it rots, I guess, in the intake hose itself. And then when it draws water, it stinks, but when it draws the water out of the hose, the fresh water comes in and it doesn't smell anymore. I literally read like 50 posts everywhere on the internet. I CAN'T FIND THE SOLUTION. WHAT KIND OF NONSENSE IS THIS? Can somebody help? There was a similar topic created, I wrote about my problem there but I haven't received any answer: https://www.elektroda.com/rtvforum/topic3364268.html

I'll add the picture of how the setup is under the kitchen. The top 3/4 connection is for the dishwasher, the bottom is for the washing machine. It's a single pipe coming under and 2 tee valves are connected to it, and the top of the tee valve the faucet connects to it.

Long description, but maybe it's crap in the washing machine and the hose has nothing to do with it.

You can easily check the hose.
Leave it as it is and the next day, unscrew the hose from the washing machine and drain the water into a clean container and smell if it smells.

Yes it does, i think i already said that smell is in the hose, but what causes the smell is the question, i changed the hose it lasted 3 months, while typically you should replace them every 5 years, i dont know whats the issue, it would make sense if dishwasher and faucet would smell too since its connected to the same source but they dont..

Maybe it's not the water from the hose that stinks. Maybe it is the pressure of the incoming water that causes the smell to "blow out" from the washing machine?
If you disconnect the hose from the washing machine and drain the water before washing, you will know whether it is the water from the hose that is to blame. And that's not a lot of work.

But how does the hose itself create that smell? If the connections under the faucet do not smell at all? I am only thinking right now that the washing machine itself infects the end of the hose connected to it, so is it the washing machine's fault? But when I removed the top of the washing machine, the mechanism for intake seems so simple. Just two 6cm little hoses coming into the drawer (or whatever it is named where you put powder). I still don't understand how 40% of the hose closer to the washing machine smells like rotten eggs, and 60% of the hose connected to the under faucet does not smell like rotten eggs?

The connections for intake water for the dishwasher/washing machine are two identical tee valves. How on earth does the dishwasher not smell, and the washing machine stinks like rotten eggs when you turn it on and it draws water from the same source for 30 seconds? I think we are still missing something, these washing machines are ****. .. Bruh. One cold water pipe supplies cold water to the faucet, washing machine, dishwasher, and only the washing machine gets infected with this sulfur/rotten egg smell. Like how on earth? I replaced the hose today but I doubt if it will help since I did that previously, it only lasted 3 months before the smell came back. It's either the water source is super bad or the washing machine is literally so bad, or the combination of the two. Although that model received good comments from customers.. What on earth is this ****.. :9 5 Sources, bathroom, toilet, shower, faucet, kitchen faucet, dishwasher do not smell like this and the washing machine does smell when it literally comes from the same source.. and it's not drain hoses because they actually smell like washing powder, a pleasant smell. Something in between the connection of the inlet hose and the 5cm hoses and drawer causes the smell. This is my only theory. Or the water itself has a lot of sulfur but it only manifests in the washing machine (edited post, a lot of typos)

Replace the hose and the problem is solved.
I had the same thing and even rinsing it with heavy chemicals only helped for a while.

Yeah, that's what I did previously and it only lasted for 3 months or something and it came back. I purchased a different hose a couple of days ago, although they are like $3 everywhere, this one is a little bit different. I installed it on Thursday (the new hose). Today, I will check if the water smells or not. But I'm not hopeful even if it won't smell because previously I replaced the hose as you said, but it only lasted 3~ months until the smell came back again. But who knows what will happen. We will see. We need some scientists to explain what the hell is going on Maybe the water has sulfur in it? And the rubber hoses somehow react to it and create the smell? Ahh, I don't even know, no point to speculate. Or as I said in a similar post where a person had the same problem, they said that replacing the machine fixed the problem. 1 guy had a corroded tee valve and he replaced it and it fixed the problem, but he didn't respond (2020 post) after that. It would be interesting to know if the smell didn't come back after replacing the tee valve and hose.

No smell after replacing the hose, but I am thinking that the same scenario will repeat itself. Because I have already replaced the hose and it came back in 3 months. If the smell will come back now with another new hose, I will update this post.

Hello.
Have you cleaned the water filter on the hose you replaced? Have you cleaned the washing machine at 90°C?

There are two possibilities. Either you buy poor quality hoses or you have incredibly nasty water.

Water filter on the hose? There is no such thing.
I cleaned the filter in the machine where the hose attaches. I think I already mentioned that I cleaned it at 90 numerous times, it's not a drain issue. Did you not read the last post? I replaced the hose, it doesn't smell, it's not about cleaning it, there is nothing to clean, the washer is clean as it can be. The smelling water comes from the hose, not from the washing machine.

poor quality hoses? Show me where you can buy "quality hoses". They are all 3-5$ in every shop possible. The only hoses that cost more than that are the ones with auto shut off valves and stainless steel ones. Every person that I know buys standard hoses and has no problem with them. It's either the water or washing machine at fault. But water would smell too from the faucet but it doesn't, neither does the same water intake to the dishwasher smell.

filter in the machine to which the hose is connected

This is what I meant, and it also happens at the hose inlet.

Didn't you read the last post?

I read it, but sometimes I read it the other way around 😉.

It's probably not a problem with the washing machine, as replacing the hose wouldn't help, but @Mice wrote about it.

I'm thinking how to check the water, maybe pour some into a jar and close it, then pour water into the second jar with a cut off piece of an old hose and close it.
Wait a day or two, maybe one of them will start to smell like you describe.

That's a creative idea, I just replaced the hose as I said like a week ago, but I threw the old hose away:/ If the smell with the new hose will come back, I will definitely try this suggestion. It sounds interesting.

Also, https://www.elektroda.com/rtvforum/topic3364268.html in this post, the person at the end said that they replaced the washing machine and for half a year there were no smells anymore. Her story was identical to mine, smell from the hose only. So if it worked for her, maybe we shouldn't exclude the washing machine. I was thinking and the only reason it can happen maybe the machine is built with poor quality parts and the place where the hose attaches and the dispenser mechanism where the water comes from the hose is somehow infecting the water over time with this sulfur smell (btw I wrote a message here too, but it was before I tried to replace the hoses, the dishwasher does not smell anymore now as I mentioned in the message in that other post)

Aaaaand the smell is back, with the new hose. Not so strong but it's already building, same rotten **** smell Woho!

I'm struggling with the same problem! I don't know what to do anymore... The washing machine is not strictly mine, because I rent an apartment and it was already equipped. Brand new, I'm the first user of it and after about 2-3 months it started to smell like a rotten egg from the powder drawer when drinking water. Everything in the washing machine has been checked and there are no odors, only when the washing machine draws fresh water The owners of the apartment think I'm crazy, because how can theoretically clean water smell?

I came to the conclusion that it may be the water source. I live in an old construction building, maybe the water has not necessary the bacteria but components to make that sulfur smell. I changed the intake hose 3 times and it stops smelling for a month or less, so that didn't help. Probably something builds up over time and you can't do anything about it. My brand new dishwasher intake hose also has the smell when I checked it out of curiosity, but of course, the dishwasher sprays a lot of water so the smelly water washes away quickly and does not affect the dishes. However, with the washing machine, the clothes kinda marinate in that and smell pretty bad after washing, lol. What I do now is just start a rinse program so the smelly water gets drawn and then I drain the water away with another program, and then I start my normal washing. Pretty annoying, but what can one do? One guy who was fixing my tee valve also said that he has the same problem and he's a plumber. He also said that he doesn't have an idea why the egg smell occurs... mystery, huh? Especially when my faucet is literally connected to the same water intake hose and the faucet never smells overnight or ever. At this point, I just blame the old building and the bad quality water they provide.

I live in a new building from 2022. The tap water is clean and does not stink. I only have a problem with this washing machine Currently, I also deal with it by running the rinse cycle so that the stinking water goes away, and only then I wash it... This is very unecological and bothersome. I have lived in different places, had different washing machines - newer and older - and I have never had such a smell Riddle...

Very interesting replies. Thank you for information. My last conclusion was that it's because of the old built house and the supply water pipes or something are old and not clean, but if you said that you live in 2022 built place then it makes no sense anymore, it's not about the age of the construction. Also another reply from justiknyna makes another headache because it puts out the theory of used-old washing machine, if brand new starts to smell anyway.

The only thing that has worked (well technically it didn't work but temporarily solves the issue) is to change the water inlet hose which is connected to the washing machine and under sink. This makes the smell go away for 1-2 months completely and then it slowly comes back. But in my apartment changing the hoses is a pain in the ass because of how everything is constructed, and anyways who changes the inlet hose every 2 months is not the solution of course. Now the question would be why the hell a fresh new hose makes the smell go away temporarily. Maybe it could be the water supply, So I live in an apartment so the water supply is coming from city lines, I have read that the water lines from whatever source it comes it can have high sulfur content (Sulfur is a mineral that exists in nature and is commonly present in water supplies). Maybe the way the mechanism is built (I'm talking about the washing machine or any other appliance which uses the same hoses for water intake) so you know that it has high pressure always in it, when it's not used maybe that bacteria travels to the end of the hose where the washing machine is connected and the bacteria builds up there (I'm saying the end of the hose where the machine is connected because I tested the start of the hose where it is connected under the sink and the water remaining there after shutting the water supply off does not smell, so kinda I guess half of the hose has a bacteria built towards the machine, and when it draws out as we said then the fresh water comes without the stinky built-up bacteria and that's why after drawing some it doesn't stink anymore. So the last current theory of mine is that the water supply lines have unfortunately higher amounts of sulfur or something, in that case there is nothing you can do, all you can do is to move to another place and pray that it has better water which won't cause these issues lol. Or maybe there is some kind of filter to buy to filter the water but I don't have an idea if such ones exist.
