Provide your customer with the following information---and they'll be more informed as to how best to use the combo washer/dryer.
Use ONLY "HE" type detergent in the following dosage (for this small-size tub):
HE (regular concentration): (1) Tablespoon Per Wash
HE 2X (double concentrated): (1) Teaspoon Per Wash
HE 3X (triple concentrated): ***NOT RECOMMENDED***
Remind the customer *not* to load the washer tub past the ***black hash mark*** that is located on a sticker/emblem---on the left side of the door/tub opening.
A fully loaded tub will *wash* fine---as long as the clothing is not compressed/pushed into the tub but---the laundry will not dry very well (taking up to 6 hours to dry laundry).
Advise the customer to select/use the TIME DRY dryer cycle rather than *automatic*.
They will need to select the desired cycle RUN TIME for the dry cycle.
After a month or so of using the TIME DRY cycle---the customer will become familiar with the amount of time needed to adequately dry an average-size or type of laundry load.
Using the TIME DRY cycle in a combo unit---eliminates/avoids using the dual THERMISTORS that are located on the DUCT ASSY.
This also allows for a higher temperature during the dry cycle (laundry dries faster).
Use the *automatic* dryer cycles for Delicates only.
Armed with all of this *very* relevant information---the customer becomes less frustrated/more relieved---that not only do they have far better *intel* on their particular combo---but that you ACTUALLY CARED to inform/educate them about it.
It's best to write this down and give it to the customer.
It's *impossible* for the average customer to *memorize* all of this:)
