100 hour wash cycle?
« on: March 04, 2015, 11:55:19 AM »

Hi Folks.  I work for a survival clothing design company.  Trying to develop some test methods to evaluate durability of products.

Is it possible to modify an old school washing machine and have it run (wash) for ~100 hours continuously?  Would the motor over heat? Which machine would be the best?

I was thinking an older analog Maytag might do the trick.

Thank you.

When the orbital drive came out on the Maytag washer, the trainer stated they ran 30 machines for 3 weeks straight 24 hours a day and had no failures. I have seen 5 fail in the years since. I would say leave the front panel off for better air circulation. Yep best machine ever made.

<<< Trying to develop some test methods to evaluate durability of products. >>>


In the mid-to-late 90s---we were contracted by a lab technician at the Dupont Company---to repair Kenmore top load washers (and dryers) that were used for durability testing of Dupont's fabric protection coating(s).
The objective was to determine at which point that the protective material---degraded/lost effectiveness.
Obviously this required extended run times (one cycle at a time)---and led to accelerated wear & tear of various components.
Our job was to repair the laundry equipment as needed.
Four washers and dryers were used for testing.

One of the requirements that the technician had to consider in her test parameters---was to choose a type of laundry washer that was widely used in residential applications---the Kenmore direct drive top load washer certainly was a very commonly used washer at the time.

Today---the prevalence of front loading washers is ever expanding (and may even be the majority of residential type washers currently in use).

The Maytag "dependable care" top loading washer---has been discontinued since the 90s (for residential use).

I'd suggest using the LG front load washer---to allow for more accurate "real world" data on the durability of the product that you're testing.

No modifications to the washer are needed/required.

As an example---the LG washer model: WM3370xxx can be used for tumble-wash testing for as long as desired by performing the following steps...

1) Add laundry to be tested

2) Add detergent (if required)

3) Press and hold the SPIN SPEED and SOIL LEVEL buttons

4) Press the POWER button---and release all 3 buttons

5) Wait for door to lock (single "click" sound)


Cold Water---press the START/PAUSE button 5 times---at one second intervals
Hot Water----press the START/PAUSE button one more time (6th time)

To enter the tumble-wash mode---press the START/PAUSE button an 8th time.
This will force the tub to tumble the laundry at approx. 42 RPMs---for as long as desired.

To exit the TEST MODE...

1) Turn off washer
2) Turn on washer
3) Select the SPIN SPEED option to the desired speed
4) Press the START/PAUSE button (this is the equivalent of a "cancel" cycle)
