Bought a Blomberg Dishwasher in Mid August of this year, 2014. It is not, and really has not been rinsing the dishes properly. I clean out the filter 2 timers per week. It's the top and bottom fron

Ensure your outlet pipe rises above the sink level, if plumbed into your sink drain or drain pipe. This will avoid the possibility of syphoning action of foul water.

There are many sites telling how to clean a dishwasher.
Just search for "How to clean a dishwasher."
Here is one link.
Your Dishwasher is FilthyHere How to Clean It

Remove lower dish basket and inspect where water drains looking for clogged inlet

Try running a cycle with bleach on an empty dishwasher water might be too soft

Check the main drain system connected to the dish washer hose pipe. Clean the junction if clogged. This smell might orginate from the pipe.

Check incoming water quality. If hard water is noticed, use softener attachments to the inlet.

Fill dish washer salt in the dispenser. Refer user guide. The salt will help softening the water to certain extent. Finally check whether rinse aid dispenser filled with the rinse aid liquid.

there is a filter on the inside bottom of the dishwasher check and clean it

hello. this will help a great deal.

First of all empty out your dishwasher, toss in two cups of plain white or cider vinegar and run it on the highest and longest cycle.

Always run the hot water in the sink first and start the dishwasher only when the water is as hot as it will get.

This wash will clean out your dishwasher thoroughly.

Then always do your dishes after you have rinsed any residue off of them before placing them in the dishwasher and I always recommend the pot scrubber cycle if you have one.

Check the following:
1. Is the overfill protection float able to move up and down
freely? Press down to release.
2. Be sure the water supply is turned on to the dishwasher.

3. Check for suds in the dishwasher. If foam or suds are
detected by the dishwasher sensing system, the
dishwasher may not operate properly or may not fill with
water.
Suds can come from:
1. Using the incorrect type of detergent, such as
laundry detergent, hand soap, or dish detergent for
hand washing dishes.
2. Forgetting to replace the rinse aid dispenser cap
after filling (or refilling) the rinse aid, or spilling rinse aid into the tub (rinse aid causes suds to occur).
3. Using an excessive amount of dishwasher detergent.

Same as above problem: I have had this dishwasher for less than 4 years and the dishes as of about 2 years ago stopped getting cleaned. I use the recommended dish liquid and rinse and lightly clean the dishes before I put them in.
What a piece of junk!! gs

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.
