4

The sieves are on the connections for raw water and soft water. Clean or replace sieves. Do not operate unit without sieves.

4.2 Chassis and cooking chamber Step

Description

1

Align tabletop units with the unit feet. Align pedestal units without EasyIn move-in system according to the tray trolley. Align pedestal units with EasyIn according to installation instructions. In addition, check roller bearing on tray trolley.

2

Replace defective door seals. Escaping steam and heat can cause damage.

3

The profile seal can be damaged due to incorrect unit alignment or lacking care. Always move the tray trolley in completely before closing the cooking chamber door.

4

Unlock air diverter and unfold. Remove calcium deposits according to operating instructions. Dismount the water intake pipe and also remove the calcium deposits

5

Bent cartridge holders affect the cleaning behavior of the WaveClean automatic cleaning.

8

Replace damaged foil immediately. Danger due to penetrating moisture.

10

Deposits on the protective basket affect the temperature measurement and change the cooking results.

11

Deposits in the air intake area under the unit must be removed with a brush and cleaning agent. A clogged air intake area causes an overheating of the control.

12

Replace damaged cover immediately. Danger due to penetrating moisture.

13

Examine steam outlet nozzles (exhaust pipe) for deposits with a flashlight. If necessary, clean cold unit with spray bottle and liquid cleaner. Use a liquid cleaner containing at most 20% sodium or potassium hydroxide. Spray the steam outlet nozzles completely with the spray bottle and allow to work. Rinsing with water is not necessary.
