Bob Load Thread anyone?

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Mike, load doesn't appear to be extroadinarily soiled.  BUT, you photos should be used as user manual loading illustrations for efficient, full dishwasher loading.  
 
I found out the hard way that if the LG dishwasher that I have is overloaded I.e. a “ Bobload” and one uses the Normal cycle, most of the load will be clean but some items, not so much. Now if I use Heavy with High Temp option, then this dishwasher runs the motor at high speed and it scours the hell out of everything in the load. I know it’s limits though. This dishwasher holds quite a bit , much more than my beloved Miele LaPearla that I had. That said I am sad to report that this dishwasher that is the current resident in my kitchen isn’t going to last another year. It has developed a crack in the left corner of the control panel and its traveling. Motor has a “ whine” to it now and sometimes the panel doesn’t respond to inputs. And the top rack is rusting in 4 spots. I am a tad disappointed
So I have been shopping around for a new one and found a Whirlpool that I do like. It’s either the Whirlpool or the Kenmore version both have the Total Coverage arm. And stainless steel tank.
 
Mike, I'm sorry it didn't last as long as you had hoped.  Glad you did give it a true BobLoad test.  

 

Yes, Frigilux can lament with you about LG dishwashers.  How long was it a resident in the kitchen?
 
Well for one thing with a Miele ...its small capacity wise. True they are great machines but the price is a tad much. I spent $2k for the LaPerla and that lasted me almost 10 years. The thing with Miele is that when they crap the bed, and the one I had with the main control going and them wanting a cool $1k to replace I thought nope not going to happen. they had already "goodwilled" the motor assembly and the delivery tubes for the middle and upper wash system. That alone would have cost me $650 just for the motor, pump, heater, switches and what ever else was in that module.

The LG 5545ST that I have now is almost 3 years old and I found out that its a common issue with cracks in the control panels, rusting racks and in places that you wouldn't even think of. Then there is the issue with the panel itself where I will press the Power button to power up and it doesn't respond like it used to...it takes 4 tries and then it powers up. I know that is a common issue as well. The LEDS for the time display has blinked a few times during a cycle. As much as I do like this machine and I wish that they were as good as their laundry products, dishwashers are a tad lacking in durability and reliability. They really need to up their game in that area.
 
gws history and bob load

What is the history of whirlpool's new global wash system (gws?) What changes were made and how well do they do on a bob load? I have always wondered how engineered their motors and their entire wash system. seems very effective. I wonder how it will do on a bob load.
 
kenmore version

I have the Kenmore version of the whirlpool dishwasher filter system and it cleans very well. I can't believe how well it cleans despite cleaning the filter 4 times a year. Must be exceptional engineering at whirlpool for sears. I guess the pumps must be beefier for whirlpool/Kenmore specs.
 
Good evening guys and gals,

Here’s my loaded Maytag dishwasher. Not the dirtiest load, not the biggest load. May not qualify as a Bob load. Before, during and after pics. I love that machine. I had a Bosch dishwasher in the previous home. Moved to this house, and it had the Fisher Paykel dish drawers. Hated them. They broke down twice in a year. Threw them out and got the Maytag. I always use the Auto cycle. No extra option selected. No heat dry. Everything comes out clean. Prewash, wash and two rinses. About 1h35 running time. I leave the upper rack in the lower position all the time. Everything fits, tall glasses, tall plates, cookie sheets. Enjoy the pictures.

Henrik, yes it would be allowed. Options selected have no influence as to whether a load qualifies/disqualifies for BobLoad certification. It's solely how "loaded" the dishwasher is as well as just how dirty/filthy the dishware/cookware is.

In fact, the need to intensify the bottom rack means there must be some pretty grungy stuff down there.
 
Well

Since currently living alone, my dishes have been sitting since monday pretty much.
I usually have the DW closed so stuff dosen't dry in to much, but have been deliberatley leaving the door open for the past few days.

Load is pretty much full by now. Just scraped stuff, so lots of dried in sauces like ketchup, mayo, salad dressing etc.
Some pans.
Cuttlery as well, of course.
Oh, and (while this is somewhat cheating) I added some choclate spread to the bottom of an especially tall cup that sits in the right front upper rack corner 3 days ago as a somewhat tribute to the peanutbutter test some time ago.

Just letting it sit another night and then running it tomorrow with some odds thrown in, so look forwards to the first real test for the G7100!
 
The time has come

Dunno how I could have fitted much more in there.

I decided against the Auto cycle and went with the Normal 60C (140F) cycle with intense zone.

While the pans are more greasy than burnt, the plates and bowls are dried in solid.

So some of everything.

Detergent is a Miele Ultra tab.

Machine just started, so lets see how this turns out!

Wanna let the dishes sit a little longer before unloading

So a cycle summary.

I chose Normal instead of Auto because it pretty much is just a full-power Auto cycle.

Timed the cycle:

Pre-Rinse: 20min, cold, medium-ish spray pressure.

Main-Wash: 1h 10min; about 5min of filling, dispensing detergent, then about 15min of heating with a 10min higher pressure phase for the lower rack (just short switches to the upper rack) right after heating followed by about 40min of pulsed washing with varying pressures and equal time for both racks. (So Intense Zone basicly just adds tha additional wash time in the lower rack.)
I think it re-heated about 20min after the first heating cause I heared a relay clicking.

Interim rinse: About 15min, non-pulsed (so full fill) with same pressure as prerinse.

Final Rinse: About 20min, uncertain temp. The manual states a temp range from 55C to 70C (130F to 160F), yet final rinse times are awefully consistent.

Active Sensor Drying: Here the time jumped up by like 20min (it dropped here and there during the cycle, but the timer stalled as well a couple of times).
I tink part of how this works is that it dosen't heat to a specific temp during the final rinse but instead uses the "guided energy usage" they introduced with their washers a few years back.
Basicly it heats until it used a certain amount of energy is used. Then it adjusts the drying time based on the temperature of the room (it checks that at the begining of the cycle using the main NTC in the sump), the load sensed and the temperature reached during final rinse.
Here it dried for 29min.

AutoOpen drying: I think the DW calculates how long it needs to do active drying until it can safely open the door and then opens the door with a fixed time left as this stage seems to last basicly exactly the same time every time.
It drains, opens the door and lets the fan run a little longer (here 5min).
After some time it just switches the fan off and sits around.
If you unlatch the door while the machines isn't done yet it asks you to close the door; once you closed the door it dosen't open the door again incase lets say you are cooking and the door is in the way and just counts down to the end.
In total this stage lasted for 24min.

So the entire cycle lasted about 2h 57min, significantly longer than estimated at the beginning, but that isn't verry uncommon for this machine at this time of the year it appears.
We'll see if that changes in the summer.

One thing I notice is that this DW kicks of a significant amount of heat into the room during drying.
My kitchen is rather small (like 10 meters squared - like 110 ft squared - with 240cm/8ish ft ceeling) but I used condensation drying DW with water pockets in smaller kitchens they never made it feel quite this warm.
