I have a newer GE portable made by Haier. When the HI TEMP wash is selected, the main wash is over 60 mins. Absolutely absurd. There’s no reason for that. I’ve opened the dishwasher up in its first pre rinse cycle and everything was totally clean, there’s no reason for it to run so incredibly long. It’s makers have no idea what their doing when it comes to programming the times on each cycle, if they actually had tested their own product they’d know an hour wash time is ridiculous. I always use the light wash which is under an hour long. This is the type of dishwasher that runs all arms at once.
Glad someone mentioned this because it’s been on my mind for so long, why are new dishwashers SO OVER PROGRAMMED!?? These machines run so long while spraying clean dishes, most dishwashers clean the dishes fully in the first ten-25 minutes. There is no need for them to run any longer than an hour. Pre rinse, wash, rinse and rinse. Done. Each pre wash should be 5 mins long, each main wash should be a good 15-20 mins long, and the final two rinses should be about ten minutes each, now that would be reasonable.
My GE when set to the Sanitize cycle takes an hour long wash, then another hour and a half to sanitize. You are not gonna tell me it takes that long for it to heat up to sanitizing temperatures, it should be a half hour at most long but that is not what we have here with most new dishwashers. They run forever, and ever and ever, while cleaning already cleaned dishes that were cleaned in the first half hour of the cycle, the rest of the cycle is a waste of energy and water as far as I’m concerned. This is why I love to use my older Whirlpool power clean so much, it’s fast and extraordinarily efficient. No BS. I understand newer dishwashers are weaker, but still, but they can still clean a load of dishes in under an hour no doubt yet all these manufacturers are over programming every cycle just about. This is a dishwasher crisis and I’m glad someone mentioned this cause it’s about time we talk about these utterly ridiculous cycle times where dishwashers are over performing.
That is literally the definition of blatant obsolescence. You literally have wet rotor magnet pumps, you literally have sine wave AC at the incoming line, you literally have low cost VFDs at your disposal. Yet decide a tiny brush motor is somehow practical for a DW. I agree, like what were they thinking.
