Limescale in the dishwasher and reduced performance? Common mistakes and how No Calc L helps
Mineral deposits, unstable temperatures and higher energy use: common descaling mistakes and how to address them with No Calc L.
Mistake 1: waiting too long before descaling
A common mistake is to descale only when the machine already shows clear signs of mineral build-up. In practice, limescale forms gradually on heating elements, pumps and internal circuits, affecting efficiency and operating stability over time.
No Calc L is designed as a periodic descaler for dishwashers. Using it monthly, or according to the amount of soiling, helps control deposits before they interfere with operating temperatures and operating pressures.
Mistake 2: using the wrong concentration
Another frequent issue is failing to adjust concentration to water hardness and the level of scale. In professional maintenance, accurate dilution matters because requirements vary with actual operating conditions.
With No Calc L, the method is straightforward: 100 ml per 1 litre for monthly maintenance, with a 10-litre final yield, or 200 ml per 1 litre for a more intensive treatment, with a 5-litre final yield. Before use, the dosing unit should always be checked and set correctly.
Mistake 3: skipping contact time or the empty cycle
Even when the right product is selected, results can be limited by an incomplete procedure. Shortening contact time or omitting the final step means the descaling process is not being carried out as intended.
For No Calc L, the required contact time is 10–20 minutes, followed by an empty cycle. The product should be used within a complete wash cycle so that limescale and mineral residues are treated consistently throughout the system.
Mistake 4: not checking dosing, product level and nozzles
Periodic descaling depends not only on the chemical treatment, but also on routine operational control. An unchecked dosing unit, low product level or dirty nozzles can reduce process consistency and overall maintenance quality.
No Calc L fits well into a simple routine: check the dosing unit, inspect product level weekly and keep nozzles clean. This helps maintain machine efficiency and supports longer service life.
FAQ
Why does limescale also affect energy use?
Because mineral deposits reduce proper heat exchange. A useful reference point is that 1 mm of limescale can mean 18% more energy use.
Is No Calc L only for dishwashers?
No. It is intended for the periodic maintenance of dishwashers and boilers.
How do I choose between monthly and intense dilution?
The choice depends on scale level and water hardness. The product brief specifies 100 ml per 1 litre for monthly maintenance and 200 ml per 1 litre for a more intensive treatment.
