How do I get the top off/or open to get to the tub? Making a funny noise like there maybe a necklace or coins stuck!! makes this noise when really spinning

'Funny noises' are difficult to diagnose, but it could be the gearbox or clutch, or it might just be the belt as the drum isn't turning. There is a belt replacement video in the link

motor/gear failure

Check the tensioner pulley that keeps the belt tight. It is next to the motor and the bearing may be shot.

Yes, your husband is correct, it is coins. There is a filter trap at the bottom of the tub. You can access this after removing the rear panel. My husband pulled 45 cents worth of coins out of ours. You will need to disconnect a hose and remove a couple of screws to get to it. Hope this helps. This has been just one of the many problems we have had with this machine.

bearings or coins stuck between drum and tub

well this is not very help full, funny noise's? hhmm? ok, cat stuck in the drum? no? lets try the bearings wearing out or braking up? broken spider? yes i did say spider, its the bit that holds the back of the drum to the driving shaft!! maybe you left a coin in a pocket and its found its way behind the drum, lets hope it dont find its way into the pump as well! broken suport springs? any number of other things????? but as for funny noise's,,, im stumped now,,oh, yes, just the one spring's to mind! my dog snores??? but he's no a very good washing machine!!!!!!!!!!!!!

The pump sounds like it may be plugged wih a coin or something like that. If the pump is plugged it will make a funny noise. Remove the pump and clear everything out of it

make sure to look really close all it takes is alittle whole in that seal anywhere to cause a leak try to look close while it is running but first dry everything you can and then run it. also make sure your door glass is clean if it is leaking down the front just alittle dirt or hair can cause a leak aswell

open top cover (two or three screws on rear and slide back) and look at rear of tub checking clearance to rear panel and nothing touching belt or pulley. whirlpools tend to have a high pitch low volume whine anytime motor operates.
you really dont want to replace that bearing. part of tub assm. $400 part plus labor

can you be more specific about the funny noise. When does it occur, during agitation or during spin? something might me stuck in the drain area of the tub and as the tub rotates it rubs against it.
