Odd remedy

[rpms]

A friend of my mom's was over last night.
She just renovated her kitchen and got rid of a 25 year old Whirlpool dishwasher that was still working. She got a new Kenmore and had 6 service calls on it in one month.Her big complaint was that nothing would come clean out of it.
The dishwasher was taken apart and nothing could be found wrong. They suggested she stop using Cascade and switch to Finish.
She did not see why switching detergent after 30 years of using the same brand would make a difference?
Finish, did not fix the problem either. Sears, said they were done with the service calls as there was nothing wrong with the dishwasher.
They told her the best thing to do was to add a cap full of cooking oil to every third load.
Apparently it works. Se said the glasses are now clean.
Anyone else heard of this?

Does she prewash/prerinse everything to the point there's no food soil going into the machine? Units with auto-sensing cycles will abort a prewash and segue into the main wash period and shorten the overall cycle time and temperature if no soil is sensed. Adding the oil (to cloud the water) may be triggering it to run longer and heat to higher target temps.

Boy, I think this gets filed under 'power of suggestion.' And why? Because AW is nothing if not an encyclopedic source for home remedies and I don't recall ever seeing this one. Why every third load rather than every load?

For all the griping that goes on here about HE dishwashers, you'd think it would have come up.[this post was last edited: 8/16/2015-17:58]

Well duh.....

Everybody knows if you want a machine to work right you have to oil it. [headslap]
