New Dishwasher On Order: GE PDT750

[washer111]

Filters

You might find that the filters generally keep themselves clean during the course of operation. Although it may still be prudent to keep an eye on the filters for now to see whether they largely keep themselves clean or not. You certainly will find large chunks of food that don't break down and move through the filter - otherwise I shouldn't think much of anything will remain.
The impellers on these pumps can do more damage than one thinks... If I put lots of rice into our machine, even without the grinder I can hear the rice being ground my a little rubber impeller!

From what I have observed on other machines (A Miele G976 SCU Plus and an "Emilia" dishwasher) with manual-clean filters, the water path during drainage seems to be designed so that the filter is backwashed clean, and even vice-versa. This, and the wash-arm often has jet/s underneath to help spray the filter clean during the wash phase - although the effectiveness of that jet still leaves something to be desired on some models, especially when frequently dealing with heavily soiled loads (My DD)...

In any case though, the self-cleaning method of those filters will always leave something to be desired, and as others have said, when they remain dirty through all the washes and rinses, your dishes aren't actually clean. They are "Clean," although with caustic detergents and high temperatures, I would not be overly concerned about that.

Awesome

I think it is awesome that GE has a machine worthy of praise. I wonder if Consumer Reports will feel the same about it.

GE seems to be finally turning things around! Didn't someone purchase a Right-Height Pair a while back?

Malcolm-- Consumer Reports gave it an overall score of 79, placing it just after a slew of Kenmore, Bosch, and a couple of KitchenAid models. I'd been looking at the TOL Bosch in the 800Plus series, which was $2,000, and also had an overall score of 79. At half the price, I decided to give the GE a shot. So far, so good! It received a Very Good rating for noise, although I'm thinking it had to be very close to Excellent; it's nearly silent---which is awesome in my book.

Hope your kitchen remodel is going well. I was without one for three weeks and it drove me crazy. I'm ready to do a lot of cooking this weekend in preparation for the holidays.

 

[logixx]

It's rated at only 42 dB, which is very quiet.

 

You know what to do next, of course.

Go and get one of these GoPro cameras and pop it in there like so:

Kitchen Remodel

My kitchen remodel is pretty much complete. Everything has been done except for lighting over the bar area. Otherwise, it is better than NEW!

I'll post a pic or two this weekend.

Malcolm,

I hope you took some before pics so we can see the transformation!

Glad to hear it's working

.........You have TWO ovens? LOL

You must do a lot of cooking.

Having to check the dishwasher filter would take some getting used to I imagine. I think I could live with LONG wash cycles like that as LONG as it's quiet.....But with my current dishwasher.....not so much. It's quite but not quiet enough.

 

[frigilux]

Mark-- One of the reasons I bought the house was due to the "dual fuel" hookups in the kitchen (gas and electric). I'd always wanted to have one of each.

And yes, I do a lot of cooking! My social life consists of having people over for dinner and Sunday brunch. I also bring food for 50 to the break room at work every Monday morning--usually a couple of coffee cakes, scones, cinnamon rolls, muffins, or and breads. Suffice to say the dishwasher is the hardest working appliance in my house.

I washed a very full half-load (upper rack) of dishes last night using the Express Wash (30 minutes) and everything emerged clean. There's also a Light Wash that clocks in at 49 minutes. Will make good use of those short cycles to make quick work of food prep loads--mixing bowls, utensils, cake pans, etc.

 

[washer111]

Spray Pressure

Nearly wrote "Spressure," Lol...

Does the machine feature variable spray pressures for each wash cycle/cycle modifier? If so, then you might find that fast washes use high pressure and more water than the longer "Custom" cycles on the machine.
Maybe it is worth experimenting!?

 

[appnut]

Does the machine feature variable spray pressures for each w

Yes, according to the specifications, this is the only model in the new series which uses a variable speed motor. There will be models above this one with variable speed motor--those will have cutlery racks as a 3rd rack like Rich's former LG.

 

[logixx]

I have seen one cutlery tray model on AjMadison. Only 39dB. Link with pictures below:

[mayguy]

Good to hear this dishwasher is working out for you!

I will share this with my customer on how well this does.

 

[frigilux]

Another test:  I made a batch of cinnamon rolls and some egg salad this morning. This seemed a good test for the 30-minute Express cycle.  I loaded everything in the top rack (save for utensils, which went in the lower rack), added a Cascade Platinum pac, chose the upper rack only option and pressed start.  

 

Whether or not this is truly a BobLoad® cannot be determined until The Great Man himself bestows the designation. Nothing in the load had baked-on residue.  The small saucepan was the only thing that saw heat, as it was used to hard-boil eggs.

 

Thirty minutes later, the machine played its comforting little end-of-cycle motif and the items were ready for inspection.  

 

Here's a photo of the load post-wash:

[frigilux]

Everything was spotless save for two items.  The dough hook was not completely cleaned, and there was a mini chocolate chip-sized spot of dough on the outside of the saucepan where the dough hook touched it. (The photo of saucepan was blurry, so I didn't include it.)  The utensils in the bottom rack were spotless. Apparently the lower rack received sufficient spray-time to take care of business.

 

All-in-all, I was very pleased.  Using the Express cycle will definitely come in handy for dispatching multiple loads of food prep items during long sessions in the kitchen.

 

And it all happened in virtual silence.  God bless us, everyone!

[frigilux]

The manual recommends using Cascade Platinum pacs (which, conveniently, happen to be my daily driver), but I didn't notice this until a few minutes ago.  Do you suppose GE has a promotional tie-in with P&G, LOL?

HalfLoad BobLoad

Given the evolution of technology for modern dishwashers, looks like I need to seriously consider a new Bobload category and designation. That being for machines which have single-rack option washing--i.e. here either upper or lower rack only (and models with upper rack only). Yes, I'll bestow the very first of this new category to Eugene. HalfLoad BobLoad designation. Although I would have loved to see what was in the lower rack for this load.

 

[mark_wpduet]

Wow - a 30 minute express wash......that's pretty quick......even for old dishwashers....

 

[jerrod6]

Detergent recomendation

Of course Ge has an agreement with them. No reason for a company to endorse another Companies products unless they do. For me other detergents like Quantum tabs work just as well as Cascade, have less or no left over scent and cost less. Nothing wrong with Cascade though - it works.

NIce

This looks like a very nice Dishwasher. Have a good time !

 

[stchuck]

Not that we are past the holiday

And many more loads of dishes, is your opinion on the dishwashers washing capabilities still favorable?

Thanks for an update

Scott

 

[frigilux]

I've had it only a week, but it has definitely put in time-and-a-half with overtime! So far, so good. The Normal cycle takes care of most loads. The household water heater is set at 140 degrees, so I shave time off moderately-soiled loads by foregoing water temp boost. Pyrex/Corning baking dishes don't appear to need the muscle of the Heavy cycle, either.  The Normal cycle clocks in at 1:15 if you don't choose the Boost Temp.  (1:51 with Boost Temp; 2:35 with Sanitize Temp).  Add nearly an hour to all those times if you choose Power Dry---which I never do.

 

The Heavy cycle takes care of heavily-soiled/baked on soils in loads of stainless steel pots and pans.

 

The 30-minute Express cycle is great for loads of bowls, utensils, and pans used for food prep. It's nice to get those loads out of the way quickly, without precarious, Dr. Seuss-like stacks piling up on the countertop. Haven't used the 49-minute Light cycle, yet.

 

I still miss the third (upper) rack for silverware & utensils, but am getting used to a traditional flatware basket.

 

I'm using the Bottle Wash feature for the first time at this very moment. We'll see how it takes care of dried-on pancake batter in narrow-necked bud vases. It's a feature that won't get much use, but I had to try it at least once.

 

The machine is so quiet; even the fill is nearly silent. I spend many hours in the kitchen on weekends, and listening to a dishwasher drone on and on all day gets tiresome. No problems with that, anymore.

 

Operational quirks:  

 

It has an odd protocol for draining.  Don't know if it's related to a soil-sensor---although I have yet to use the AutoSense cycle---or if there's another reason, but it drains for 2 seconds, pauses for 1 second, drains for 2 seconds, pauses for 1 second, then drains for 5 seconds and pauses for about 12 seconds.  Then it drains for 2 seconds, pauses for one, finishes draining, and begins to refill.  I haven't noticed if it does this on all the drains or just the first one.

 

Prewash Option--  I can see why the manual recommends using detergent pacs.  This is what occurs after the first fill when you add the Prewash option to a cycle: It alternates spraying water between the lower and upper racks every 5 seconds for a couple of minutes, then drains and refills.  The first dose of gel or powder would be wasted. Haven't paid attention to what happens after that, but the Prewash adds about 30 minutes to a cycle.  There is a more traditional (but brief) first wash if you don't choose the Prewash option.

 

One downside of its hushed operation is that you really need to sit down in front of it and pay attention to what's happening if you're curious about how it operates. I have not done that, yet.  I notice the first few minutes of the cycle, and then don't think about it again until the Clean light comes on.

 

Manual-Clean Filters--- The ultra-fine filter (pictured in a post above) gets soiled more readily when using the Express cycle several times, consecutively; and I have confessed to being lax in the dish-scraping department. I suppose the machine doesn't run long enough to allow the filter to clean itself off, to a degree.  It's so easy to remove and give a quick rinse under the faucet that it doesn't bother me at all.

 

The 2-watt fan continues to run for at least an hour after the Clean light signals the end of cycle.  The fan shuts off and doesn't turn back on once you open the door. Haven't used the Power Dry option, so don't know if it behaves similarly in that instance.

 

I give the machine two thumbs up at this point, but it's still very early in the game.

Draining protocol

Eugene, I was at friends' house for Thanksgiving and they had a new WP TT with filter system. When it drained each time it did a similar sequence.

So there's no capability for having detergent during prewash, just the main wash?

 

[logixx]

Same here. My Bosch will drain, spray, drain, spray and drain after the main wash. I suppose it's to create turbulence in the water to wash the filter.

You say that prewash sprays water "for a couple of minutes" and then drains but adds 30 minutes to the cycle. What does it do in the remaining 25 or so minutes? Does it then extend the regular prewash that would have taken place anyway?

 

[frigilux]

My bad: It's a Presoak Option, not Prewash. Too late to edit and correct the term in the post above this one.

Bob: You can add gel or powdered detergent for the prewash/first wash. You simply pour it onto the indentation on the closed detergent lid. See photo up the thread. When using a gel, I pour the prewash dose directly into the tub so it can go to work a little quicker. If you choose the Presoak option, it basically gets wasted, as explained above. If you don't add the Presoak option, the prewash/first wash is longer and the detergent is better utilized. At any rate, the cycles appear custom-made for using a pac, which gets released during the main wash. The manual recommends using a pac---specifically Cascade Platinum.

Alexander: I haven't paid attention to find out why the Presoak option adds 30 minutes to a cycle. Will plant myself in front of the machine for a whole cycle (when I can find the time) and document the sequence of events.

 

[henene4]

The spray-drain-sequence is used to self clean the filter. The water is (normally on this system) drained from the inner filter. You will see the cahnnel to the recirculation pump will go from the side walls of the filter housing away anywhere towards the pump. And then, there should be a small draining channel at the bottom of filter housing (maybe covered or anyhow hidden). This is where the drainpump is connected to.
Now, the DW washes and the filters fill up with gunk and residue. The big filter area visible from the top will catch havier/bigger particals, the fine filter smaller ones.
Now as the first drain starts, water flows the opposite direction through the filter as it would during the wash cycle. Means this flow removes particals from the filters. The stop/spray then is used to help the bigger particals on top of the filter settling down again and then being again drained towards the middle of the filter, down into the pump (sorry for that bad english). This is the self cleaning part of the filter.
Further, this explains why the short cycle keeps the filter uncleaned. Maybe this routine is removed completly to safe time or there are just not enough drain phases that can clean the filter...

GE version of Reversa-Jet

Well, it only took General Electric 49 years to catch up with the reversing spray arm that Tappan used in its 1965 Reversa-Jet.

Below is a link GE's short video.

Power, style, and innovation? This GE Profile has it all.

Early Adopter

Well, now every line has a cutlery rack: Monogram, Café and... Profile.

[frigilux]

I figured the PDT760 would make its debut fairly soon, as it is referenced in the user's guide for my PDT750. I miss the cutlery rack from my LG, but the 760 wasn't available when I needed a new machine. Oh, well. "Worse things happen at sea," as my dad used to say.
