Poor Wash Performance Information

• Critic acid or salty foods like ketchup or mustard left on the utensils too long before washing.
• Water softener salt spilt when filling water softener (some models/markets only)
• Low grade stainless steel being less resistant to corrosion in damp dishwasher environment.
• Steel and silver items loaded together and reacting with each other.

• Avoid prolonged contact with acidic or salty foods. Pre rinse acid or salty residue off before washing.
• Ensure all spilt salt is cleaned up before a wash is started. 
• Use a high grade stainless steel in the dishwasher, or ensure you remove these items right after the dry period has finished.
• Separate all steel and silver in the cutlery basket.
• Ensure the rinse aid is full and correctly set.

Iridescence on Pots and Cutlery

(purple, blue, green or yellow tinge)

• Caused by vegetables like potatoes and cauliflower.
• Can be caused by impurities in the water supply like iron or manganese oxide.

• Is completely harmless and is easily removed using a cleaner.
• Limited on what can be done on incoming water supply except adding a water filter to the incoming supply.

• Caused by a formation of silver sulphide due to sulpher containing food residues like mustard, eggs and mayonnaise.
• Formation of silver oxide due to bleaching agents used.  (oxidation)

• Avoid prolong contact with sulphur based foods and try using a pre rinse cycle if dishes being left for some time in the DW.
• Try using a multi benefit detergent tablet with silver protection ingredient e.g.Finish Quantum tablets.
• Silver items should really be washed by hand, not in a DW.

• Aluminum will change colour due to the DW detergent being used.
• Caused by the aluminum being unsealed, and reacting with the detergents.

• If aesthetic colour change is not acceptable, suggestion is to wash all aluminium by hand washing.
• Follow the pot manufacturers recommendation for washing.

• The reason for enamel damage and colour fading is frequent dishwashing.
• Some glazes have limited durability to detergents used in DW, and limited numbers of cycles they can be washed before the colours start to fade.

• If aesthetic colour change is unacceptable, suggestion is to wash these dishes by hand.
• Or try using a finisher protector which helps eliminate colour fade and and glass corrosion.

• Patterned glass unwashed

• If aesthetic colour change is unacceptable, suggestion is to wash these types of glasses by hand.

• Same patterned glass after 50 cycles washed in a dishwasher.

• Usually caused by hard water (lime scale)
• Mineral deposits in the water.
• The water softener in your DW may not be working or incorrectly set for the incoming water hardness.  (some models/markets only)

• In most cases this can be removed by soaking and cleaning in household vinegar.
• If using a powered detergent, try changing to a muti-tablet that has additives included to help in hard water situations.
• Some multi tablets can work in hard water up to 375 ppm.  
• Check the water softener (if fitted) is set on the correct harness level for your incoming water supply.
• Ensure the water softener has been filled with DW salt, if not refill and continue to top up with the correct salt as required.
• Ensure the rinse aid is full and correctly set in the dispenser.
• Try using more detergent.

• This can be caused by incoming water quality with the  water being very soft.
• Water softener (if fitted) is incorrectly set.
• The composition of the detergent formula can also scratch glasses.

• Use a short or lower wash temperature cycle if possible.
• Or use the glass wash cycle if your dishwasher has one.
• Check the water softener (if fitted) is correctly set for the incoming water hardness.
• Once scratched this is irreversible.

• This can be caused by poor loading of dishes.
• Puddles of water can form due to loading and some shapes of dishes.
• Detergent tablet still dissolving in the last rinse due to incorrect wash cycle chosen. ( too short or too cool)
• Over dosing of detergents.
• Rinse aid not being used, or has run out.

• Ensure the dishwasher is correctly loaded and all dishes can get water penetration which will help wash and rinse the dishes.
• Ensure the dishes are stacked correctly and can not tip and retain water.
• Select a cycle that suits the soil level and type of  detergent being used, using a short wash cycle may not give a  detergent tablet enough time to fully dissolve.

• Rinse aid has run out

• Fill rinse aid dispenser.
• If rinse aid is visible and there is a level indicated, check the rinse aid setting is correct.

• Usually caused by washing dishes with a lot of tomato food soil left on the plates.

• Pre rinse dishes by hand before adding to the tub, this will prevent the staining.
• If already stained, try using a  dishwasher cleaner which should help remove the staining.

• This can be normal, but amount can vary.
• Using a low temperature wash or using the ECO cycle option.

• Use a warmer wash temperature and see if the water level reduces.
• Using ECO cycle decreases water temps so the residual heat is reduced, causing more condensation to form, this then will form around the top tub edge.
• Some water on this edge is quite normal.

• Incorrect wash cycle used for solid level.
• The rinse aid is empty.
• Incorrect loading or over loaded.
• ECO cycle selected

• Ensure that the correct wash cycle is selected based on solid level.
• Check the rinse aid dispenser is full and correctly set to the right level.
• Ensure you load the dishes correctly that they receive good wash penetration.
• Lower temperature wash cycles like fast/delicate have very low rinse temperatures, meaning the dishes will appear wet after the cycle has finished.

• Incorrectly stacked dishwasher
• Short or too low wash temperature cycle selected.
• Not enough detergent being used.
• Blocked spray arm
• Jammed spray arm.

• Ensure the dishes are stacked that they receive good water penetration during the wash.
• Ensure you select a wash cycle based on soiled level, usually a normal or heavy wash have higher wash temperatures.
• Try increasing the detergent level.
• Check the spray arms were not jammed by something falling through the base rack and stopping the spray arm from rotating.

• In some cases tubs can be stained due to the incoming water quality.
• This tub is an example and has completed 5000 high heat cycles in a lab.
• The tub has turned brown due to the high iron content in the incoming water.

• Use a DW descaler type cleaner, this one is available to purchase through F&P.

• Fill the dispenser up with the Dishwasher cleaner as shown.

• Fill the dispenser up with the Dishwasher descaler cleaner.
• Run through on a normal wash cycle.
• Ensure to follow manufacturers instruction on the box.

• The tub after one clean, which has removed most of the heavy staining.
• Some results may vary.

• In some cases tubs can be stained due to the incoming water quality.
• Or due to certain foods staining the plastic.

• Try running an empty tub on a heavy cycle with the maximum level of detergent to see if this can remove the staining.
• If the staining does not disappear you could use a recognised brand of dishwasher cleaner.
• Follow the manufacturers instructions on the bottle.
