My dishwasher won't clean the dishes properly - very poor cleaning results with residue left on the dishes.

Hello

Clean the internal parts of the dishwasher. Use a clean wet cloth and wipe down the inside including the racks and the sprayer arms. Remove the upper arm by unscrewing the center bolt. Clean both sides before replacing.

Check the water pressure. The dishwasher requires inlet water pressure between 20 to 120 psi. If the water pressure in the line is too low, proper rinsing will not occur.

Check the water temperature. The dishwasher performs at optimal levels with 120 degree water. Check the hot water heater for needed adjustment.

Use the right detergent. The dishwasher requires detergent designed specifically for dishwashers. Other detergents will leave spots, residue or food on dishes.

Set the machine to the proper cycle. The dishwasher offers a variety of cleaning cycles. Select the appropriate cycle for the type of cleaning required.

Load the dishwasher properly. An overloaded machine will result in dishes not being cleaned thoroughly.

Their are quite a few reasons for a dishwasher to have white residue on your dishes. I will list some steps to take and help you get your dishwasher working again.
1. Are you low on Rise Aid? Most dispenser have a 1-6 setting right under the cap. Make sure your set between 3-4 for the best results. This additive helps in cleaning and drying your dishes and most manuals will say its required for best results.
2. What type of detergent are you using? If you are using the dollar budget type product you will get very poor results. If you are using a name brand make sure it does not have rise aid already included. Too much rise aid could cause white residue as well.
3. Do you have hard water? Hard water can make it more difficult for your dishwasher to clean. Be sure to use a dishwasher cleaner such as Dishwasher Magic at least once a month. Your dishwasher does a great job at cleaning dishes but when it gets dirty it needs a little help.

clean the filters or get new ones.make sure your water in is connected to the hot water not cold.Also put new rubber O rings on the spinning arm water sockets.

Hi,

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...

Hi,

Probably a blocked spray arm. Remove the top spray arm and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results.
Yes there will also be a filter in the base of the unit to clean. This needs to be done regularly to avoid food getting into the working parts of the unit.

the problem is hard water. there is a product at www.dishwasherfilter.com that filters out these hard minerals that cause those spots and leaves your dishes crystal clear every time. it is very affordable and has a money back guarantee. you will love this product and your dishes again.

Switch to a brand name powder detergent like Electrosol or Cascade. Never use ultracheap, generic DW detergent powder in any dishwasher. Run a load with dirty dishes and see the results are.

If cleaning results remain poor open the sump area by removing the lower spray arm and the filter assembly. Remove all debris in and around the sump area. Inspect the impeller down there to make sure it is not broken and that it spins freely. Clean the filter well in the sink. Reassemble. Also, check all spray arm holes for blockage.
Run a load of dishes and check cleaning results. If problems continue, you almost certainly have a failing wash motor and replacement is your next step.
Post here is you would like more assistance. Good Luck!

Sounds like you have a calcium issue with your water. if you have a water softner time to get it serviced. also you can get a cleaner for the dishwasher to clean it out called Dishwasher Magic.
