No worrys mate
out of the five we had two machines with deformed seals , one of the hassles we have encountered is that customers will wash the bin out ald leave it with the lid open in the sun, In certain areas, were all five machines came from it can easilly reach 45deg c , the rubber would become soft and deform when the bin was closed causing a faulty seal. This is only a presumtion as we did try and replicate this but could not get the exact results.
funny thing is if you look further up this thread you will see a pic of my dc23 that I use for cleaning up after building work here at home. its bin seals tight with no dust residue on the outside of the tank and it really gets abused.
