The pump on my dishwasher is broken as the rotating blade has become detached from it's mounting. I only therefore require the part with the rotating blades. The picture appears to show the same part that is currently on the machine, which, if opened up, has to be turned into place before being screwed closed. Can you tell me whether this is the type of assembly required for this part? Also, someone has posted that you require new hose clips as the ones used on the machine are single use. I might not need them anyway if the assembly is as above, as I'll just replace the part with the blades, however I need to know the assembly is the same, and if not, whether I need new clips. Thanks.
