SQ front loader prewash
Has a prewash and I use it all the time.
Especially for loads of tidy whities.
For two reasons. First, the detergent never makes any suds in the prewash because antiperspirant residue in T shirts poses a challenge. The pre wash takes care of that.
Second, it preheats the clothes and tubs, so that when the main wash fills with hot again, it stays piping hot. No need for a heater or lengthy delays heating the water.
And I suppose third it substitutes for a warm rinse in situations where one would be useful.
I love it. Wouldn’t want to be without the option. Results in impeccably white and clean tidy whities and linens and sheets every time. It’s also good in Winter for keeping a warm load warm during the main wash cycle.
After the pre wash, the SQ spins on low speed for a minute or so while draining, but it doesn’t go into a full high speed spin.
There’s only one catch. The SQ adds chlorine bleach in the pre wash, which is of course the wrong time. Best to let detergent and enzymes work alone for awhile first. So the work around for that is to add chlorine bleach to the drawer after the pre wash has filled. Most of the time the bleach compartment will have pre wash fill water in it, so I just remove the drawer and dump that water out if jiggling the drawer doesn’t drain it. Or, the bleach could be diluted and poured in via the main detergent compartment at any desired delayed time during the main wash. Also the main wash detergent must be powder, because liquid in the main wash compartment will merely run into the prewash water. Not a problem for me because I use powder anyway in the white loads where I use the prewash option.
