Does anyone have the wiring diagram tech sheet or cycle sequence for this model? And build date?
Hotpoint Model HDA-460-03

Help Support :
I need a picture of the control panel. I've seen a photo of interior online and have found a picture of the control panel with woodgrain look on it. It's a BOL Hotpoint. Built anywhere from late 1970s or early 1980s through 1986 to 1988. Cycle sequence is prewash, rinse, (maybe a 2nd rinse) main detergent wah, 2 post wash rinses and dry. I doubt there are 3 post wash rinses tht were found on higher end models for Potwasher cycle that mine had.

3rd Final Rinse
This is one of the things I want to find out, including if they just removed the one fill and one drain ramp on the timer drum and left everything else the same. There is possible evidence saying this with a latter 1985 model...
It is interesting, from a 1977 service manual the model earlier to this one (HDA-400) had three final rinses (see pic), but a mid 1980s model (after HDA-460) had only two rinses. Interestingly, it seems like both the 1977 and the 1985 models have the same sump, but the latter ditches one final rinse.
Around 1986 this changed again, GE went from three to two post main wash rinses adding a 3rd post wash rinse. In 1990, right before they discontinued porcelain Hotpoints, that kept the same number of rinses (two pre wash, wash, 3 final rinses) but tweaked the fill times and cycle times a hair.
I'd be able to find the cycle sheets if I had access to GE's service and repair tech site.

Sumps and Rinses
Non reversing motor (drain solenoid) Hotpoints from the 70s had two sumps: type As from early 70s and type Ds which came in the late 70s.
Type A always had 3 final rinses to my knowledge, while type D appears to have had 3 final rinses in their first production run then switching over to two final rinses.
Why the 3 was considered optimal then two has always intrigued me. It seems like GE and Hotpoint had internal debates about how many rinses and water changes ought to be used when they went with the type D design which had less carry over water than type A and continued into the 80s across all their lines. I'm one of those people who wishes the rooms had been bugged lol, what I'd give to hear the conversations amongst the engineers and designers over the years on this hot button topic.
Me, personally, I'd have told them to drop the drain solenoid and attach a separate shaded pole drain motor to the sump and with with two rinses and a longer fill time to compensate for the full evacuated sump- but I somehow think I would not have kept my job lol.

Based on the Serial number, this dishwasher was manufactured in December of 1980.

Typically, but I don't haven access to this machine.
Are you or any techs registered to the GE service matter site?
