GE

The one thing i like about GE is that they are still a brand that can get a filthy load clean in less than 2 hours.
Our GE TT can do a normal wash with medium soil in just over an hour, including dry time.
 
GE speed cycle

MY GE TT has a "Speed Cycle", get average dirty dishes clean in about 35 minutes. I'm not quite sure how it differs from the "China " cycle that runs about the same length of time.
 
Intensive Programmes and High temperatures

Hi all, I hope you are enjoying the season.

I'm in the same position as Serge and want a new dishwasher. I was looking at the Bosch as their trays are very well organised, however, they seem to concentrate all their programmes on Quick and Economy which I don't use, unless you want to buy the very expensive machines, which we can't afford at present.

Do very Hot and Intensive programmes really make a difference, or do you think the standard normal wash is enough?

Many thanks

Rob
 
Hot & Intensive Programmes

I have a Bosch that will be about 4 years old now. It has three automatic sensor programmes for the delicate, normal and intensive programmes.

I have found through experience with various machines over the course of the past twenty years, that a fully loaded machine requires the intensive programme at 65-70deg C.

The normal cycle in my Bosch is:
cold prerinse, then if water is clear of debris, use it for mainwash; one cool rinse; heated final rinse; drying. The mainwash temperature is usually 50-60deg C. as the sensors calibrate it 'on the fly'.

The intensive cycle is:
heated prerinse (keeping it for hot mainwash if it is suitably clear); two warm/cool rinses; final hot rinse; drying. Mainwash temp is somewhere about 60-70 deg C., again done 'on the fly'.

When I say fully loaded, I mean pots and pans, and crockery, cutlery, glassware, serving spoons, cafetiere, etc.

If you rinse everything before placing in the machine, a basic machine would probably do you.

However, if you merely scrape, I would suggest the intensive programme equipped machine.

In saying that, basic machines seem to have a better range of programmes now; including an intensive 70deg prog.
 
With my Miele, I find that the Normal 50-60deg Auto program will clean 95% of loads without an issue. It gives a cold Prewash - Reuses the water for the main wash if clear, 1 or 2 cold rinses depending on soil level and then a 65deg Final rinse. If I have a days worth of crockery with a few saucepans and a frypan this cycle always works fine.

The only time I use the pots and pans cycle is if the dishwasher is loaded with greasy baking pans with food encrusted. I use the Pots and pans cycle in that instance as it gives a warm pre-wash (I've had it add two additional ones) 75deg Main wash, 2 cold rinses and a 75degC final rinse.
This cycle also adds 30 minutes to the wash, so the entire cycle takes about 2.35 (With 2 extra pre washes it took 3.08 :) )
 
Can anyone who has a Bosch dishwasher tell how how big a plate they can put in the lower rack when the upper rack is at its lowest position, without interfering with the upper spray arm? 11 inch, 12 ?
How tall a glass can be in the upper rack in the lower position?

thanks,

Serge
 
If the Bosch has RackMatic then...

"To accommodate large or oddly shaped dishes, RACKMATIC® allows you to raise or lower the premium upper rack at the touch of a lever (even when full), giving you up to 14" of space on the bottom or 10" on top." (from boschappliances.com)

RackMatic lifts/lowers the upper rack by about 2 inches so that's 12/14 inches in the lower and 10/8 inches in the upper rack.
 
We've had a few Bosch dishwashers in different houses over the years and I have NEVER done any more than scrape anything.

You basically remove any large lumps of food from plates, bowls etc.
Turn machine on to a normal cycle. Make sure that you use a decent detergent, I find Sun All-in-one Power (Unilever), Finish (reckitt benckiser) and Ecover all extremely effective. Also make sure you keep the machine supplied with salt for the water softener and with Rinse Aid to ensure good streak-free drying and your results will be flawless.

Bosch (and most European machines) have a primarily self-cleaning filter. During the wash the water is sucked horizontally across the filter and through the fine meshes removing all particles. When the machine empties, the water is sucked downwards through the middle of the filter and simply through a large grid that catches anything that's managed to get through. The pump can handle most normal sized food particles and they are simply flushed down the drain and the mesh filters are basically self-cleaned.

There is a wide mesh collar sticking up out of the filter, this prevents any larger items from ever getting into the filter system and they will sit on top of the filter tray at the end of the cycle.

Normally, all you need do is look into the bottom of the machine and you'll find any really big items of food e.g. beans, vegetables, pasta, nuts, etc that was not scraped off the dishes. You'll see these just sitting on the top of the filter system and they can easily be removed by just picking them off. There's no need to actually remove the filter.

The filter can be removed and checked and cleaned every month or so. However, most of the time I don't find anything in it!

Also, I suspect that this system removes more fine food particles than the old US-style disposal systems as there's no risk of fine particles being recirculated through the machine. It also means that the spray arms and jets are extremely unlikely to block up.

See the picture below for the filter centre unit. It sits in the middle of a large fine mesh tray.
 
One more thing

Remember the water level in the end of the machine will only get to the top of that collar on the top of the filter. There's normally no water flowing down the centre of the filter assembly.

The wash pump sucks water ghrough the fine mesh on the outside - (there are 2 layers of it, one fine and one VERY fine)

When the drain pump starts the water is sucked through that grill on the top and down the centre of the filter. It flows along the mesh and cleans it!

Some machines can even give the filters a reversed wash pump blast with clean water !!
 
I Love My Bosch

Oh man I love my Bosch. Everything comes out squeaky clean. I have an open floor plan, and it is so very quiet. That is the main reason I purchased it. And I love that the heater is under the tub, not an element inside the dishwasher. That means I can safely put plastics anywhere, yes even on the bottom rack. I use Palmolive gel detergent, Wave Jet rinse aid and get excellent results.
 
Bosch filter cleaning

I find that the underside of the central filter flange (dark grey, with the blue arrows) is a grease trap - it really needs weekly attention on my machine.

Apart from that, no problems.
