How to repair a Whirlpool top load washer that leaks during the spin cycles

Your washer is configured differently than the Whirlpool mentioned, but all washers are susceptible to drive and suspension issues. One of your suspension springs may be broken, or there could be a problem in the belt drive system.

The front panel should come off fairly easily, though it may be difficult to fully inspect everything without removing the other sides. The machine is still operational without the sides, you should be able to locate the problem by running it through the end of a spin cycle. Just be sure to stay well clear of moving parts.

If you can manage getting the panels off (locating all the screws can be tricky), and identify the problem, you probably can manage replacing the broken part. It is certainly cheaper than hiring someone, and it certainly does not warrant a replacement machine. (Unless you just want an excuse for a new machine)

I'm not sure if you can buy parts for the transmission or if you'd even be able to repair it to working order anyway. Being that it's a $300 assembly, isn't it new washer time? If you can't find individual parts for the transmission, the point is moot. I had one with a bad main bearing; it would agitate but couldn't spin under load. I'll be the first to admit that I'm just a parts swapper; entirely disassembling a washing machine would not make me any money and would probably optionally cost you the same, in lost time (and more parts when it breaks again next year; you'd still have an old washer).
