DATE: February 28, 1995

TO: AHAM (Dishwasher Standards Group)

FROM: ' Carl E. Adams, Appliance Standards Division

SUBJECT: Preliminary Dishwasher Engineering Analysis

The Department was notified per your December 2, 1994, letter that the

Association of Home Appliance Manufacturers (AHAM), with its members, will be

conducting negotiations with non-industry groups regarding a joint comment to

DOE pertaining to the next round of dishwasher standards (Docket No. EE-RM-94-

403). On January 24, 1995, AHAM provided the Lawrence Berkeley Laboratory

(LBL) with industry data so that LBL could initiate the engineering analyses.

LBL has conducted preliminary engineering analyses which are based on the AHAM

submitted data except for the motor.design options. In reviewing the

analyses, the Department does have some questions regarding the analyses and

data. However, to meet the proposed meeting schedule, the Department is

forwarding the preliminary analyses, which are attached for your distribution

to all negotiating parties fordiscussion and comment, and will be working to

resolve questions. Additionally, the Department is aware that AHAM plans to

submit new data regarding adaptive controls. If the additional data is

received and/or the Department's.questions result in new or revised data, then

the Department would provide an update to the attached analyses prior to your

planned March 21, 1995, negotiation meeting.

Please direct any questions regarding this material to Marc LaFrance of my

staff at (202) 586-8423.
