De-scaling
For the best water quality, Nisbets Essentials recommend that a water filter is installed to the mains water
supply, particularly in hard water areas. Doing so will reduce the build up of limescale and contaminants in the
water tank thus maintaining energy efficiency and prolonging the life of the appliance.
To de-scale the appliance:
1. Turn off and disconnect the appliance from the power
supply.
2. Remove the cleanser inlet cap. Then pour a solution of
de-scaler and water into the appliance via the inlet.
Note: Always use a suitable de-scaler and follow the manufacturer's instructions on the length of time
required to soak, water temperature and on how to dispose of the solution safely.
3. Drain the solution and discard safely.
4. Re-start the appliance and let it run 2 or 3 boiling cycles to flush out the system and remove any de-scaler
residue. Empty the appliance afterwards.
5. The appliance is now ready for use.
IMPORTANT: Failure to de-scale or maintain will invalidate your guarantee.
