Servicing and maintenance

Rinse the suction tube at every container change under running water. Re-
move crystallised detergent residue.

Ensure that both vent holes (a) in the caps are open.

Put the suction tube back into the container. Slide the cap downwards until
the container opening is closed.
5.4 Changing the detergent product
Danger

Mixing different detergents can lead to efflorescence that can lead to a failure of the deter-
gent dosing device. This is applicable even if the new detergent is from the same manufac-
turer.

The dosing tubes and the detergent dosing device must be thoroughly rinsed with water
before the new detergent is used.

A new detergent product usually requires a new setting of the detergent dosing device. Assign the re-
quired work to a service engineer authorised by Winterhalter to attain good results.
If this is not done, the warranty and product liability of Winterhalter Gastronom GmbH expires.
Procedure:
Danger

Observe the safety precautions when handling chemicals and the dosage recommendations
on the packaging.

Wear protective clothing, protective gloves and protective goggles when handling chemicals.

Do not mix different detergents.

Remove the suction tube from the container and place it in a water-filled container.

Rinse the dosing tube and the detergent dosing device with water. To do this, use the "prime dosing de-
vice" function several times (

‎
12). The frequency depends on the length of the dosing tubes.

Place the suction tube in the new detergent container.

Use the "prime dosing device" function several times (

‎
12), to replace the water in the dosing tubes with
detergent.
5.5 Priming the dosing devices
Dosing devices must be primed when air is reached in the dosing tubes because the containers were not
exchanged or refilled in time (

‎
12).
6 Integral water softener (special equipment)
By softening the inlet water, limescale build-up in the machine and on the dishes is avoided. For the integral
water softener to work correctly, the salt container must be filled with regeneration salt.
INFO At the commissioning of the machine the authorized service technician measures the water hard-
ness and saves it in the machine's electronic control unit.
6.1 Lack of salt display
A pictogram appears in the display screen when an empty salt container requires refilling.
The display disappears after filling the salt container, as soon as approx. 3 wash cycles
have been completed and part of the salt has been dissolved.
