-   I have the same problem. I have heard of many people with this problem on front loader washers. I don't know how to fix it but I do know it's a design flaw in a front loader machine. The door has to seal tightly to prevent water from leaking out when the machine is running and if you shut the door after using the machine it allows the smell to develop quicker. Even with the door open the machine doesn't dry out as quickly as a top loader.
We have been sucessful in holding the smell down by spraying the seals around the front of the machine with a bleach or vinegar solution. Unfortunately you have to stick your whole head inside the tub to do a good job and that's hard to do.

I have an Ultima 1200 washer/dryer that has clogged a few times (E15), and hence been rectified. However, I now get the same message, even after checking the filter, outlet pipes, drum, I have also run the impeller and it seems to function fine. Additionally I have also checked all of the electrical terminals and given them a clean. Any other ideas? Many thanks in advance
