Why my dishwasher is giving poor Wash Performance?
Check the water pressure.
The dynamic water pressure to the dishwasher should be 2 to 4 bar.
Check the wash cycle selection.
Select the appropriate cycle for the dish load. Selecting a short or light wash cycle may save water and energy, but may not provide proper wash action for a heavily soiled load. If food soils remain on the dishware after the cycle, a longer cycle may be required. Please consult the Owner’s Manual.
Check the water temperature.
Proper water temperature is essential to achieve optimum results from your dishwasher and the detergent. Hot water is needed to dissolve and activate the detergent so that it can loosen and remove common food soils. Wash water temperature should be between 55 to 65 deg C and rinse water temperature between 82 to 87 deg C
The hot water heater should be set to deliver at least 20 degree C water to the dishwasher
To check the water temperature, run the hot water at the kitchen sink and measure the temperature of the running water with a candy or meat thermometer. Adjust the temperature of the water heater accord
Check the amount of detergent and the water hardness.
The amount of detergent needed depends upon: water hardness, the amount of food soils left on the dish load, and the temperature of the water going into the dishwasher. Do not use liquid detergents not made for automatic dishwashers.
Use a Rinse Agent.
Rinse agents promote wash and dry performance by causing the water to sheet off of the ware inside the dishwasher. This prevents water spots from forming on the glassware and dishware.
Check the dishwasher loading.
Make sure dishes are loaded properly to insure that water can reach all of the soiled surfaces in both racks. Please consult the Owner’s Manual.
Here are some common loading guidelines for assistance:
Place glasses with the open end facing downward to allow proper washing action.
Do not allow flatware to nest. This prevents proper water distribution between the surfaces. Load flatware, except knives, with some handles up and some down to prevent nesting. For safety, knives should always be loaded handles up.
Do not block wash system parts including spray arms and towers located at top / bottom.
Excessive amounts of food may clog the dishwasher filters and reduce wash performance.
In models without extending wash towers, the spray arm may be removed to check the filter underneath. Inspect the fine filter. It should be clean. If not, clean out all the filters and spray arms. To prevent this from happening, scrape dishes before placing them in the dishwasher and pre-rinse the dishes to remove solid particles.
