Water hardness and softened water, your partner for success!
One of the first things to check is the quality of the water supplying your dishwasher. Having a water softener will guarantee water free of limescale, which remains the main cause of whitish deposits, especially on glassware.
This water softener requires careful attention in terms of adjustment (volumetric or time-based) and especially the correct replenishment of softener salt , the only guarantee of its proper functioning.
As you will have understood, you therefore need to check this hardness, which must be less than 10°Th, using test strips or control devices.
Water pressure during washing and rinsing: maintain your professional dishwasher!
In the function of a professional dishwasher, washing as well as rinsing are ensured by arms or ramps in the case of conveyors on which injectors are placed.
It is through these arms or ramps that the pressurized water will be able to dislodge the dirt .
It is therefore obvious that if these arms or rails are dirty, scaled, have blocked injectors, etc., the mechanical action of the pressure will greatly decrease.
In this case, even the best product in the world won't be able to help you.
You therefore need to pay particular attention to the maintenance of your dishwasher, not hesitating to dismantle the arms or ramps, the injectors and to descale/degrease them if necessary.

Pre-washing or descaling: give yourself every chance of success.
The professional dishwasher is a fantastic tool which, compared to your household dishwasher, will not only be more efficient but will do in 5 minutes what your household dishwasher might take 40 minutes to do... But don't forget that it's not a magic tool and understanding the overall dishwashing cycle is essential.
If your dishes are heavily soiled with grease and stubborn grime, pre-rinsing or rinsing them with a spray nozzle will significantly improve the results. This will facilitate the action of the detergent and prevent overloading your dishwashing water with dirt and food scraps.
Adjusting and maintaining the dishwasher dispenser
Liquid dishwashing product is injected by dosing pumps ( dishwasher doser ) thus allowing the correct amount of washing product and rinse aid to be added to each wash cycle.
Proper settings are also crucial for optimal washing results . Adhering to the detergent dosage recommended by the manufacturer is essential and depends on your water hardness. Hard water requires a higher dosage to effectively neutralize limescale. You should also check the condition of the detergent dispenser hoses and replace them if necessary.
