Title says it all.
20+ year old dishwasher making a grinding noise - old enough I can't find an exploded diagram to aid in disassembly.
Appears to have a telescoping tower in center - in that tower there's a piece of plastic clearly broken on the end, but it won't come out w/o disassembly - and I can't figure out how the tower comes apart (no obvious Torx screws like shown on other Maytag d/w)
Should I take the kickplate off first to check for water leaks at the motor?
Thanks for any help!
