could you have knocked the power connection to it? I don’t know where each are in relation to each other on your machine but iirc when I replaced a busted pump on ours (a bobby pin had got in there and pierced a hole right through the half inch thick plastic!) they weren’t that far apart and the blade style power connectors can be prone to slipping off in some cases.
In any case I think you’ve got a fairly good case against @anon29812515
