Dishes have soap residue despite using rinse aid. Machine is quite abrasive on coffee mugs etc. Unit is Fisher & Paykel DD605SS

A good quality rinse aid and forget economy mode its a waste . Also leave the dishwasher drying until it stops , it can be hard to hear but the LCD will still be on . also most plastics will be left with a soapy looking stain permanently .How much powder and use a goog quality one. another common problem is the soap dispenser being left open or coming open during the cycle.
check the drain hoses and the inlet tap is turned on enough
Cheers

According to the manual, there is a cooperative effort with the rinse aid solution and the non eco mode. There nothing that says a drier circuit exists and if they are not drying then it is rinse aid or loading issues. However if you look behind the kick panel of the machine there is a plastic envelope with the technicians information on testing.

Agitator can be removed easy,Take out the fabric dispenser cup,
Reach down inside the agitator & undo the wing nut, left to undo.
Take out agitator & clean & the bottom of the bowl,
For a more better clean fill machine with hot to high water level & leave soak over night,Do heavy duty wash in the morning to remove scrud.

If rinse aid levels in dispensor are ok then check if it is being used. the rinse aid setting may be set too low.

Instructions Things You'll Need:

• Vinegar or lemon juice
• Gel dishwasher detergent

1. dishwashers have a rinse aid dispenser. If your dishwasher has this dispenser, fill it up periodically and it will release the appropriate amount of rinse aid automatically at the right time during the wash cycle. This will help your dishes rinse more cleanly.
2. Rinse aid in solid form
   Some older dishwashers or basic models do not have an automatic rinse aid dispenser. In this case, you can buy rinse aid in solid form that attaches to your dishwasher rack. Solid rinse aid can be hard to find in stores because it is not commonly used, but it can be purchased online.
   
3. Vinegar or lemon juice
   Appliance repairmen will tell you that one of the common problems they see with dishwashers is the buildup of excess detergent. If there is too much detergent in your dishwasher, your dishes will not rinse cleanly, no matter how good the dishwasher is or how much rinse aid you use. To clean the excess detergent that has built up inside your dishwasher, put 3 tablespoons of vinegar or lemon juice (concentrate is fine) in the empty dishwasher and run the dishwasher through a complete cycle with no dishes. Do this twice, for two complete cycles of the empty dishwasher with only vinegar or lemon juice added. The acid in the vinegar or lemon juice will break up the detergent that has built up in your dishwasher's interior.
   
   After you have cleaned the detergent buildup from the inside of your dishwasher, follow the steps below to keep the buildup from happening again and to help your dishes rinse cleanly and prevent residue from accumulating on the dishes.
   
4. Gel dishwasher detergent
   Switch to a liquid or gel dishwasher detergent. Any brand will do.
   
5. Fill one compartment half full Dishwashers will effectively clean dishes with much less detergent than manufacturers often recommend. The bleach in the detergent, combined with the extremely hot water used in the dishwasher wash cycle, will clean and sanitize your dishes completely, even in small amounts, and using less detergent helps prevent buildup and residue from accumulating on your clean dishes.
   
   Fill only one detergent compartment(the one that snaps closed) half full with gel detergent. Snap the opening closed and run your dishwasher as you normally would. Your dishes will come out sparkling clean with no buildup or residue, plus you'll save money by using less detergent!
   

Hi,

The scum, film and white residue problems have started since the reduction of phosphates in dishwasher detergents.

Here is a tip that will help you to solve the problem of films, residue, and scum in your dishwasher.

Dishwasher Residue and Film on Dishes

Try cleaning the rinse aid with hot water. Clean all the orifices.
Or you can try the two in one soap tablets.

run some calcium lime and scale remover throught the unit on an empty wash cycle just to get rid of any build up that may be there.
turn the rinse aid down to about half way.
also check the phosphours content of you washing agent.
there is a lot of factor involved with leaving film on the dishes, it could also be residual soap content that is sticking to your dishes.
reduce the amount of soap a little.does not matter if it is liquid or powder.
once every three months you need to run cleaner through the machine.
last thing but very important make sure the incoming water temp i no lowe rthan 120 degrees.

Suds? If you use dishwashing detergent you shouldn't get suds. If a small amount of sink type dish soap is left on a dish before loading it into the dishwasher this can happen. I would use several rinse and drain cycles with the racks and dishes removed until the suds are gone.

Never use any type of liquid dish soap made for sinks. The same thing that makes suds in the sink will make even more in the dish washer.

Hope this helps!

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.
