I have seen multiple reports of people having similar issues with Eco bubble washing machines where the plug fuse had melted and scorched the socket.
We bought the machine in early 2016 and had been running fine until 2 days ago when the cycle failed to complete and we got an error code of UC and it started to smell funny. At closer inspection of the plug, we found out that the fuse in the plug had melted the inside of the plug and the socket was scorched. Upon on research I found out that this has happened to others with Eco-bubble models with exact same description of the problem. We called Samsung and explained that we have come across this thread and problem with other machines and that we are worried about the safety of a 5 year old machine (IMO washing machines should last longer than 5 years). I was told that an engineer will come and inspect and that they take this very seriously. When the engineer came he advised us that this machine needs to be replaced as it is a fire hazard and he also raised an issue with the fuse in the plug among other things. Upon contacting Samsung, we got told that all they can do is replace the plug and one other part as a "one-off repair" without expressing interest in investigating this matter further to understand how this happened and whether it can happen again or not. We really don't feel comfortable using this machine again as there is no explanation of why this happened in the first place?
When we asked Samsung about their awareness of this problem with other similar models of similar age, their answer was its outside of warranty so they cant comment on it. We think Samsung should take more responsibility than this with their products and investigate this issue in more details. But anyone who has ever dealt with Samsung's UK customer services will know that this will never happen as it is really like talking to a wall.
We hope that this message will add to the other similar messages and will make Samsung take notice of the problem.
