I called the detergent company to report a defective bottle, but turns out there was some sort of formula change due to a new regulation. Apparently mixing the two together in the auto-dispenser causes them to harden and clog the dispenser. So I tried just pouring it into the manual dispenser, slightly better but the dishes weren&amp;#x27;t really clean. I called my dishwasher repairman who just told me to buy Finish tabs and we would be fine.&lt;p&gt;My mother called me weeks later saying that six of her tenants complained that their dishwasher was broken and she had already replaced one (two of the dishwashers were less than two years old). I told her to just gift them all a tub of tabs from Costco which worked.</text><parent_chain><item><author>twic</author><text>I once met a chap who told me he used his dishwasher without any powder or soap at all, and it still worked.&lt;p&gt;Now, maybe he was making it up.
