Whirlpool Load & Go Dispenser: Fixing Blue Stains on... | appliancefaults.com

Technical Background:

The MCU (Microcontroller Unit) controls the dispenser valves by sending a 120V AC signal to the appropriate solenoid valve. The valve opens, allowing detergent to flow into the wash drum. Problems arise when the valve malfunctions, leaks, or the dispensing path is blocked.

Symptoms:

US homeowners are reporting blue stains appearing on their clothes after using the Whirlpool Load & Go™ dispenser.

Possible Causes:

Overfilling the Load & Go™ dispenser with too much detergent.
Using a detergent that is too concentrated or not designed for automatic dispensers.
A malfunctioning dispenser valve that is leaking detergent.
Clogged or partially blocked dispenser nozzles.
Detergent residue buildup within the dispenser system.

Solution:

1

Unplug the washing machine from the 120V AC outlet and turn off the water supply valves.
2

Remove the Load & Go™ dispenser drawer and inspect for any visible cracks, damage, or detergent buildup. Clean the drawer thoroughly with warm water and a mild detergent.
3

Inspect the dispenser nozzles for clogs. Use a small brush or pipe cleaner to remove any obstructions. A toothpick can also be used.
4

Check the dispenser valve. Use a multimeter to test the solenoid valve for continuity. A reading of approximately 1.2k ohms is typical, however refer to the tech sheet for the specified range. If there is no continuity, replace the valve.
5

If the valve has continuity, but may be sticking, apply 120V AC briefly to the valve terminals. Listen for the valve to click open and closed. No click indicates a bad valve. Use extreme caution when applying voltage.
6

After cleaning and testing, reassemble the dispenser drawer and plug the washing machine back in. Run an empty wash cycle with hot water to flush out any remaining residue.
7

Observe the dispenser during a test wash with a small amount of properly diluted detergent. Ensure the dispenser releases detergent at the correct time and in the correct amount.

Safety Warning:

Always disconnect power (Lock Out, Tag Out - LOTO) before servicing. High voltage components are present. Wear appropriate safety gear, including eye protection.

Prevention:

Regularly clean the Load & Go™ dispenser drawer and nozzles. Use only High Efficiency (HE) detergents in the recommended concentrations. Avoid overfilling the dispenser. Run a cleaning cycle monthly with a washing machine cleaner.

Expert Tip:

To access the diagnostic mode, press and hold the Start/Pause and End Cycle buttons simultaneously for 3 seconds. This will display any stored error codes.

Look for the HE symbol on the detergent bottle. It is usually a small, circular symbol with the letters 'HE' inside.

•Where can I find the correct replacement dispenser valve?

You can find the correct replacement valve by searching online using the model number of your washing machine. Local appliance parts stores are another option, but call first to confirm availability.

•How often should I clean the Load & Go™ dispenser?

Clean the dispenser drawer at least once a month, or more frequently if you notice detergent buildup or residue. The nozzles should be checked and cleaned every few months.
