Hey Folks!

Decided to do a fun little experiment soon!

I was looking around at spray arms when I realized, all WP built dishwashers have the same spray arm locking tabs, which then made me run to find a TotalCoverage/Powerwave spray arm. Upon finding one new, I was ready to order it, but quickly realized something...

Powerwave spray arms rotate around a gear coming up from the lower spray arms hub, something my Kenmore 15113 does not have. So I continued to look at more spray arms by WP until I noticed a Kitchenaid spray arm, the X shaped arms do not contain any gear to rotate around and just lock right onto the lower spray arm hub, so i bought it.

When the arm arrives, I'll record a video with the current arm and then after the X shaped arm. My dishwasher operates with both upper and lower spray arms on at once with no alternating, so it will be interesting to see if the unit will starve for water considering that the X shaped arm is a lot bigger than the current one. To its rescue though it has much more smaller holes (but more) so that may or may not compensate.

Water usage for a lightly soiled load on my unit is 3.3 gallons on the Normal cycle, A Kitchenaid's water use for a lightly soiled load on the Normal cycle is, 2.7 Gallons, Im assuming it HOPEFULLY will be fine...If not, looks like I'll just have to switch back to the old one.

Right away though I noticed the holes under the X shaped arm, it looks like there are 4 holes directed towards the heating element, which could be an indicator to more efficient water heating. However, the X shaped arm is going into a totally different type of setup, so it's either going to be a big hit, or a total miss. The current spray arm only has 2 big holes directed at the spray arm.

There are also more jets on the X shaped arm but with smaller holes. There are approximately 13 jets, with more directed towards the corners of the rack and tub. They all seem to be the same size, on the current arm they arm there in numerous sizes and shapes and also contain LESS jets with only 10 on the arm.

This will be a very interesting experiment to do, despite it not being a powerwave arm, if the X shape arm succeeds in experimentation, I will have it in there permanently and note the results of how it cleans. I'll keep you all posted!

I saw a barely used fire engine red Big Chill dishwasher at the ReStore last week.  A look inside revealed a 4-way hydro-sweep wash arm. 


Good to know for those who want the retro look but a brand new machine, and are willing to pay about triple the price for it.

It has arrived!

The arm arrived today!

First impressions of it, I was expecting it to be much heavier, seems roughly more or less than the weight of the current arm, but that said it does feel a little more solid too... HOWEVER, the spray arms metal parts feel like all it is, is just shiny plastic rather then metal. Dunno, it's probably a very thin sheet of metal making it feel like that, doesn't have a tab for a heat deflector, and all KA's with this sprayer seem to not contain any heat deflection whatsoever, so that may be an indicator to it being true metal.

Another thing I noticed is the hole orientation under the arm which aim for the heating element, there are 2 jet like holes (rather than 4 like previously thought). That being said the current arm in my Kenmore contains two holes which basically spray onto the heating element, unlike the KA arm which jets water to the heating element. I'm also very impressed at the targeted jets placed at all four edges of the arm, seems like it will be very effective at reaching the corners of the tub.

Been there done that, the arm works quite well too. Still using it.
