I have a twenty year old Maytag washing mac...

Hey, you've got a very cool Maytag...they were made so well 20 years back!
A few things to check:
You can access the insides very easily: just remove the two phillips screws on the bottom of the front panel of the machine... down by the toe kick area.. then tip the bottom of the panel forward until the top clips come free of the top cover of the machine.
There are two screws that hold the front corners of the top cover down... you can remove them with a nutdriver.
Then you can tip the top up and check everything.
First thing the fill hose:
There is a fill hose at the top of the drum. It tub top cover. The hose should be hooked into the hole in the tub. If it isn't, the water will pour out the hose, over the top of the drum and alot will end up running down the outside.
Also check the drain hose that connects the tub to the pump. It may be leaking.
Also, check the gasket/clamp that holds the top of the outer tub to the main outer tub.
Lastly check the drain hose connections in the machine.
These machines pump a good amount of water out during the drain portion of the cycle.
it's also a good idea to standby and watch during a spin/drain cycle to make sure the drain standpipe in your home isn't backing up when the machine drains..
Let me know how you fair... this is a great machine and worth the fixups.

hello. i can help you. unfortunately, your problem has numerous possible causes.
Your washer can develop several types of leaks. You can track down a leak based on when it occurs:

During fill only
During drain and spin only
All the time
During fill only If the washer leaks only during the fill cycle, check these:

• Air-gap device -The air gap is a small device found on most washers that prevents the wash water from being siphoned into the household water supply. It's located either mid-way along or at the end of the black rubber hose that comes from the water-inlet valve. Often it's made of translucent plastic. If one of the air-gap components deforms or cracks, you may need to replace it.
  
  
• The tube -There's a rubber tube that runs between the water-inlet valve and either the air-gap or the inlet spout. If it cracks or breaks, it can cause a leak.
  
  
• Inlet spout -Most washers have a plastic spout near the top of the main clothes tub that directs the water into the tub. If the spout cracks or breaks free of its mounting, it can cause a leak.
  
  

During drain and spin only A washer that leaks only during the spin cycle often has a leak in the main drain hose. Inspect the entire hose and correct any problem you find. Alternatively, the steel or plastic outer tubs can rust, split, or be punctured. This may be most visible during large loads and high water levels. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details.

All the time If the washer leaks all the time, check these:

• Hot and cold water fill hoses - Check the hot and cold water hoses from the household plumbing. If either hose is leaking, tighten it or replace it, as appropriate.
  
  
• Main tub seal - The main tub seal is located between the transmission and the outer tub. It's the primary water seal in the outer tub for the transmission-shaft entry point. If this seal leaks, you can see the leak by opening up the machine's main access panel while the machine is full of water with a small amount of detergent in it. The leak appears at the underside of the outer tub, at or near the center. This seal is difficult to replace. You probably should call a qualified appliance repair technician.
  
  
• Pump - If the pump leaks, you can probably spot the leak when the tub is full of water. The pump has two or more black rubber or plastic hoses attached to it and usually has a drive belt that spins the pump. If the pump is leaking, you need to replace it.
  
  
• Outer tub - Over time, the steel or plastic outer tubs can rust, split, or be punctured. If this happens, you may have to replace the entire outer tub--but that may not be an economical repair to make. Consult a qualified appliance repair technician for further details.
