Bill, I guess I"m not understanding the issue with the washer being on the right and the dryer being on the left with the dryer door being drop down and not side-swing, shouldn't matter what direction the washer lid is hinged. The house I basically grew up in had this very same arrangement. The only time I found it to be a pain was when we had the 1950s Norge Timeline dryer with the door push-to-open button on the far left side of the machine next to the door. The Norge was hinged on the left side for the washer and the dryer was drop-down just like Whirlys. And when the Kenmore 800 came in, no big deal. Now, when the Filter Flows came in, that was another story. The door for the dryer was hinged on the right and it swung from right to left.
My dispenser acted a little bit differently on my 1986 DD Lady Shredmore. I always knew on the lectronic ones, the detergent dispenser was activated for the first minute or so of the wash fill. On the mechanical ones, you had to set the timer at the absolutely longest point for each wash cycle. The water flushed for 2 minutes and it was tepid, not even warm. Definitely not simply hot valve open. I really dind't like this arrangement for hot or white loads because by the end of 2 minutes, the amounjt of water in the tub was half-way betweeen nothing and what was ex-lo on the later level selector, so not much hot water if it was a super small load. I quit using this dispenesr after about 6 months because the 14 minute or 122 minute (PP) wash cycles were just too rough on clothing. Things dind't need to be beat to death on normal for that long. As for the bleach, it was siphoned in when water ran through it at the 2 minute mark of the wash cycle, I wish it had been 4 or 5 minutes like on yours. And as for the rinse, it didn't flush softner until the machine started agitating for the rinse and if the clothes didn't start circulating within 5 seconsd, something might get hit with a burtst of dilluted softner from the sipenser. Unfortunately, if 2nd rinse was selected, it dind't shift the dispenser execution to the 2nd rinse, always only the first rinse.
I never liked the fact the only spray rinse was during the last spin, never a spin-spray rinse on normal or delicate on the spin between wash & rinsee, only on PP. Seaers finally rectified that lack of 1st spin spray rinse when they came out with their UltraRinse feature on their washers.
