This came in with complaint of no suction. If you take off the bin there’s loads of suction at the motor side of the bin but very little at the hose side with it refitted. You can see daylight through the air passage from bin to hose connection so that’s not blocked. The only thing remaining is the filter so I removed that and held it against its connector with the bin removed. Again, hardly any suction could be felt into the filter, although it looks quite clean. The answer must be a new filter but how can it be blocked when it looks clean? 😕
