Whirlpool Washer: Water Puddle in Detergent Dispenser -... | appliancefaults.com

Technical Background:

The washer's Main Control Unit (MCU) controls the water inlet valves by sending 120V AC to the appropriate valve solenoid. The dispenser valve directs water flow into the detergent, bleach, and fabric softener compartments. Incorrect water pressure, siphoning, or valve leakage can cause water to remain in the dispenser.

Symptoms:

US homeowner observation: Small puddle of water remaining in the detergent dispenser of a Whirlpool washer after the wash cycle has completed.

Possible Causes:

Excessive water pressure during fill.
Siphoning effect due to incorrect drain hose system.
Faulty dispenser valve.
Clogged or restricted dispenser nozzle.
Defective water inlet valve leaking slowly.

Solution:

1

Turn off the water supply to the washing machine at the wall shut-off valves.
2

Disconnect the power cord from the outlet.
3

Inspect the drain hose connection to the drain pipe. Ensure it has an air gap of at least 2 inches above the standpipe.
4

Check the water inlet valve screens for debris. Remove the inlet hoses, use a 5/16-inch nut driver to remove the screens, clean them, and reinstall.
5

Remove the detergent dispenser drawer and inspect the dispenser nozzle for clogs. Clean with a small brush and warm water.
6

Test the water inlet valve coils for continuity using a multimeter. A reading outside of the specified range (typically 500-1500 ohms) indicates a faulty valve. If faulty, replace the valve.
7

If the problem persists, temporarily reduce the water pressure to the washer by partially closing the supply valves. If the issue resolves, consider installing a pressure regulator.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use Lock-Out Tag-Out (LOTO) procedures. High voltage components are present. Incorrect repairs can cause electric shock or property damage.

Prevention:

Periodically clean the dispenser drawer and nozzle. Inspect and clean the water inlet valve screens every 6 months. Ensure proper drain hose system with an adequate air gap.

Expert Tip:

Some Whirlpool washers have a diagnostic mode. To access it, rapidly press any button (except power/start) 6 times within 12 seconds, ending with the start button. This can display error codes and aid in troubleshooting.

Frequently Asked Questions

•What is the proper drain hose height for my Whirlpool washer?

The drain hose should extend into the standpipe, with an air gap of at least 2 inches between the end of the hose and the drain opening. The top of the standpipe should be no lower than 30 inches and no higher than 96 inches above the floor.

•How do I test the water inlet valve with a multimeter?

Disconnect the power to the washer. Disconnect the wires from the water inlet valve coil. Set your multimeter to the ohms setting (Ω). Place the meter probes on the valve terminals. A reading of around 500-1500 ohms is typical. An open circuit or short circuit indicates a faulty valve.

•Where can I find replacement parts for my Whirlpool washer?

Replacement parts can be found at appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your washer's model number handy to ensure you order the correct parts.
