I have a maytag neptune MAH5500BWW. Everytime the water company shuts off the water to repair a leak, the tub fills with water, sometimes overflows onto the floor. Works just fine when there is pressure in the line. Any ideas?

The Inlet Valves have failed, or the power to them has failed.

Maytag Neptune Bearing Replacement How to Replace Neptune Tub Bearings

I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249

Sounds like a leak either in the bottom, connector or water valve for your water inlet line. Visually finding the leak is your best bet, then you know what parts are to be replaced.

Your tub seal leaked water into the tub bearings causing them to fail. Maytag only offers the bearings as part of the outer tub assembly and the repair can be pricey. A little research may turn up a service company in your area that has the tool to replace only the tub bearing. The repair becomes more affordable that way.

water leaks out of the plastic box where you put the detergent/bleach/fabric softener, from the OUTSIDE of the box onto tub, drips down tub on to metal tray and into drawer. Anyone had this problem?

two problems here,
your shaft seal is running on its last leg
the sound is unmistakeable and always described the same...
the water issue, you probably have a trickle leak through the cold water valve
the mixing valve is quite an easy repair, but I would have to say with all honesty, it probably time for a new machine
the hub seal is a tub replacment call
2 hrs of labor if hes good
and the tub runs around 500.00 dollars
sory for the bad news

1. Water inlet valve. It may not be able to shut completely when the electricity to it has been turned off. The valve may leak and drip water into the clothes tub. Water may accumulate substantially and overflow. Remove the washer's cabinet to access it.
   
2. Water level switch. This switch senses the water level in the clothes tub. It is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. As the water level in the tub increases, the air pressure in the tube increases and activates the switch when the water reaches a certain level. When the switch is obstructed, it cannot tell the water to shut off and the machine overflows.Clear it from any obstruction.
3. Air-hose. It is connected to the water level switch through a tube. If the tube or hose is cracked or broken, no enough pressure builds up to trigger the switch and shut the water supply off. Check it for any obvious damage.
   

replace water valve in the washer. Serial number is needed to find the correct part number. It's likely 22003834, but call any parts supplier with model/serial numbers to verify.

Good luck,

Here is the solution I found that worked for me, there is a small drain hole at the bottom of the boot that is connected to a drain hose. Remove the hose and clean out to make sure that it has not become plagged. replace hose and reattach boot. Mine stoped leaking imediately.

This can be caused by water collecting in the door to tub seal. Best repair would be to replace the door seal.
