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.
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)
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.
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)
