Dishwasher running out of rinse aid when dispenser is still half full

[maytaga806]

This post doesn’t just apply to new dishwashers, but to older as well. I’ve never understood this and maybe someone can elaborate.

Everytime I notice streaks and spotting and residue on dishes means for me in my water type that I’m out of rinse aid, or so I would think. I look into the dispenser to find it at least half full still. It never dispenses all of the rinse aid in the dispenser, ever. My 2006 Whirlpool does this, my 2019 GE portable does it. The 2019 Maytag at my family’s house doesn’t seem to ever leave any rinse aid behind, nor the previous Maytag, once it’s empty, it’s truly empty. It just seems like in both of these machines that once they hit the halfway mark of rinse aid, it can no longer dispense rinse aid. I’ve read before that your supposed to keep the dispenser full at all times, is this why?

Once I add more rinse aid to the full mark the streaks spotting and residue are gone again of course after running dish cycles. How does the rinse aid dispenser work anyway? I sort of understand it on my whirlpool as I’ve taken the front panel off and watched it run it’s cycle without it with the back of the rinse aid dispenser exposed, but still not sure. It’s always been a mystery in the back of my mind but now it’s really irritating me cause I go thru so much rinse aid nowadays and it’s quite costly in today’s economy and I’d love for my machines to just USE ALL OF IT.

Is something wrong with my dispensers or is this behavior normal? I do know the dispensers work, I can smell the rinse aid during the final rinse or straight after it’s done. Also the final rinse gets slightly sudsy from it as well so I know they are working when the dispensers are full, it just seems they don’t work at all when they are halfway full. My dishes always come out new looking, so when that isn’t the case and there is white residue and spotting that’s how I know no more rinse aid is being dispensed and I’ll refill the dispenser to the top and everything comes out like you’d expect again, shiny and glossy.

It's not really costing you any money, just making you fill the dispenser more often. Though more frequent fill-ups may mean more spills which wastes a little rinse agent each time. But it isn't like you can't get half the contents out of each bottle of rinse agent you buy.

And refilling it more often means I’m going thru the bottles quicker, making me have to buy a new bottle much sooner and more frequent than what’s typical or normal.

Rinse aid dispenser problems

Not sure why this is happening to you, maybe there’s a little more pressure when the reservoir is full and it dispenses better, but it doesn’t make a bit of difference if you have to fill it when it’s half empty it doesn’t cost a penny more it’s kind of like filling your gas tank on your car with the gas tank is half empty all the way empty, but with the dishwasher, you don’t have the cost of driving your car to the gas station, lol

I guess you have very hard water. I’ve never found rinse agent makes any difference. Our water is about seven grains of hardness. If you use the proper dishwasher pod the glasses come out sparkling every time at our old whirlpool power clean dishwashers.
