Claim on your insurance if you can, let them sort out the concrete thing,you couldn't afford to sue a concrete manufacturing company for a washer part,you must know your way around a washer(you had to strip it down a bit and diagnose the fault)if it works ok I would Gaffer tape the parts together using the full roll if necessary and run it, if the problem is sorted champion,if not bin it,throwaway society is rife I'm afraid,I hate waste but you have to cut your cloth as they.
