Customer Questions and Answers for Water Inlet Valve Assembly by Whirlpool

4.89 (64)
By: Whirlpool
Part Number: OEM18027165
Manufacturer Part Number: WP3979346

The Water Inlet Valve Assembly is an OEM part for Whirlpool washing machines.  This part controls the flow of water into the appliance during the fill cycle. This assembly consists of a valve that opens and closes to allow water from the household supply to enter the washing machine at the right times and in the correct amounts, depending on the selected wash cycle and water temperature settings.  

Causes of a bad water inlet valve can include sediment buildup, which restricts water flow, wear and tear that impairs the valve's operation, or electrical issues that prevent the valve from opening or closing properly.

Symptoms of a bad Water Inlet Valve Assembly include:

  • The washing machine not filling with water
  • Water filling too slowly or overflowing
  • Unusual noises during the fill cycle
  • Water not reaching the desired temperature

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

Amber C. for Model Number Maytag MTW5740TQ0

Our Maytag Performa worked fine for several years, then suddenly stopped drawing cold water, and would only wash on hot. We replaced the hoses and the water inlet valve assembly. This didn't solve the problem, and it still didn't draw cold water. I removed the hot inlet hose completely, and attached the cold hose in its place (cold water going in where the hot should be). This worked great for about two weeks. A few days ago, the washer started pausing a very long time on the "rinse" portion of the Normal cycle. Today, it will not draw any water on any cycle and makes a loud buzzing. I can also hear dripping inside the machine somewhere, but no water is coming from underneath, yet. Any advice would be appreciated.

Answer

Amber, The newer "energy efficient" washing machines operate on a slightly different theory and you have to have both hot and cold water supplied to the washer, or at least cold water to both fill valve inlet connections. Depending on the temperature selected the water temp. switch cycles power to both solenoids and they cycle off and on to maintain the selected water temp. Since you have a new valve, and hoses and plenty of water supplied to the washer you'll want to check or replace the water temperature switch WP8578335. The switch has an internal PCB that can fail or weaken and make the water temperatures erratic.
