Speed Queen Washing Machine: Removing Dark Grease Marks... | appliancefaults.com

Technical Background:

MCU logic and voltage paths.

The Speed Queen washing machine's main control unit (MCU) controls the motor, water valves, and drain pump. The motor receives variable voltage to control wash and spin speeds. A faulty transmission seal allows grease to leak into the wash drum, contaminating clothes. The MCU relies on feedback from sensors and timers to regulate the wash cycle. Proper voltage (120V AC) is required for the motor to operate correctly. The timer controls the duration of each wash phase. Any leakage of grease requires mechanical intervention; there's no electronic solution.

Symptoms:

US homeowner observations.

My Speed Queen washing machine is leaving dark grease marks on my clothes after washing. I've noticed it more frequently lately, and it's ruining my laundry. I've tried different detergents and wash cycles, but the problem persists. The grease marks appear to be coming from inside the machine.

Possible Causes:

Worn or damaged transmission seal leaking grease into the wash drum.
Over-greasing of the transmission during a previous repair.
Grease breakdown due to age and high usage, becoming more mobile.
Contamination of the wash drum with external grease or oil from other sources.
Loose or damaged agitator causing excessive friction and grease release.

Solution:

1

Disconnect the washing machine from the 120V AC power outlet. Lock Out/Tag Out (LOTO) procedures are essential.
2

Remove the washer cabinet. This usually involves removing screws from the rear panel and lifting the cabinet off the chassis.
3

Inspect the transmission for signs of grease leakage. Pay close attention to the seal around the drive shaft.
4

If grease leakage is evident, replace the transmission seal. This may require specialized tools such as a seal puller and installer.
5

Clean the wash drum thoroughly with a degreasing agent to remove any residual grease. Use a non-abrasive cleaner.
6

Reassemble the washing machine, ensuring all components are properly secured.
7

Test the washer with a load of old rags to check for continued grease leakage. Monitor for any unusual noises or vibrations.

Safety Warning:

LOTO and high voltage warning.

Always disconnect the washing machine from the power source before performing any repairs. Lock Out/Tag Out (LOTO) procedures are crucial to prevent accidental electrical shock. Be aware that some components may retain a charge even after the machine is disconnected. Use appropriate safety equipment, such as insulated gloves and safety glasses. If you are not comfortable working with electrical appliances, consult a qualified appliance technician.

Prevention:

Specific maintenance.

To prevent grease leaks, avoid overloading the washing machine, which puts excessive strain on the transmission. Regularly inspect the machine for any signs of leaks or unusual noises. Follow the manufacturer's recommended maintenance schedule, which may include periodic lubrication of certain components (check the service manual). Use the appropriate amount of detergent; excessive detergent can accelerate grease breakdown.

Expert Tip:

Trade secret or service mode sequence.

Speed Queen washers have a service mode that allows you to run diagnostic tests and access error codes. To enter service mode, typically you simultaneously press and hold the start/pause button and one other button (check the specific model's service manual). This will allow you to pinpoint the source of the problem more accurately before disassembly.

Frequently Asked Questions

•What type of degreaser is safe to use on the wash drum?

Use a non-abrasive, pH-neutral degreaser specifically designed for washing machine drums. Avoid harsh chemicals like bleach, which can damage the drum and seals. Follow the degreaser manufacturer's instructions carefully.

•How difficult is it to replace the transmission seal, and what tools are needed?

Replacing the transmission seal can be moderately difficult, depending on your mechanical skills. You'll likely need a socket set (both metric and imperial), a seal puller, a seal installer, a hammer, and possibly a gear puller. Consult the service manual for detailed instructions.

•Where can I find the service manual for my specific Speed Queen washer model?

You can usually find the service manual on the Speed Queen website or by searching online using your model number. Some third-party websites also offer service manuals for a fee. Always use the manual specific to your model for accurate information.
