capable of automatically adjusting washer operation or washing conditions, 

without the need for consumer intelventioll and/or actions, based on 

characteristics of the test load placed in the clothes container. Examples would 

be clothes washer control system independent selection, modifications, or 

absolute control of water fill level, wash water temperature, agitation and/or 

tumble cycle time, number of rinse cycles, spin speed, etc. 

Note: The energy consumption of any adaptive system which relies on the use 

of, detection of, or the presence of either soil, soap, suds, or any additive 

laundering substitute or complimentalY product to alter the "normal" operation 

of the clothes washer must be determined following the field test procedures 

defined in section 6.1; unless it is verified that a more energy intensive value 

would result following the test procedures defined in section 2 and section 3. 

1.21 "Manual control systems" refers to the type of washer control system which 

requires that the consumer make the choices that determine washer operation 

or washing conditions, for example; water level, wash/rinse temperature 

selections, and wash time before starting the cycle.

6.1 Nonconventional Wash System Energy Consumption Test

For washer controls or systems that cannot be adequately measured for energy

consumption by the test procedure, or cannot be calculated using a procedure

generally accepted by DOE and other manufacturers, a field test must be

conducted.

The field test shall consist of a minimum of 10 test units and 10 base units, with a

minimum of 50 cycles per unit. The units shall be monitored in such a way as to

accurately record the total energy consumption per cycle. At a minimum, the

following must be measured and recorded throughout the test period for each test

unit: Hot water usage in gallons, electrical energy in kilowatt-hours, and the cycles

of usage.

• Warm Rinse

Procedures common to both non-water heating and water heating

clothes washers:

- Measure hot water consumption only of rinse.

- Test the "hottest" rinse cycle available.

Includes deep and spray rinses.

Test maximum load size and maximum fill level.

Test average load size and fill level (if adaptive).

Test minimum load size and minimum fill level.

Additional procedure unique to water heating clothes washers:

Measure the total electrical energy for a warm wash cycle and

hottest rinse cycle: use maximum, minimum, and average

(adaptive) load sizes.

Subtract the total electrical energy for the warm wash cycle

with cold rinse (previously determined in Section 3.5) from the

warm wash and hottest rinse cycle to obtain the additional

electrical energy for warm rinse.

Dear Carl:

As we agreed at the Home Laundry Test Procedure

Workshop , attached are the Temperature Use Factor

(TUF) values developed by the home laundry

manufacturers when it was anticipated that a quick

change could be made to the test procedure.

You will recall from our discussions , that these

TUFs had variable effects on the energy factors for

different models and thus , caused us considerable

difficulty. The decision was then made to not

pursue a change in the test procedure for the shortterm but to work toward a longer term major overhaul

of the test procedures.

Sincerely yours,

JTW:ms
