Descaling

The appliance must be descaled at regular intervals in order for 

it to continue operating correctly. "Descale the appliance" 

reminds you of this.
You can only dispense with descaling completely if you 

exclusively use softened water.

The descaling consists of:

■

Descale (approx. 30 minutes), then empty the evaporator 

dish and refill the water tank

■

1st rinse (20 seconds), then empty the evaporator dish

■

2nd rinse (20 seconds), then remove the remaining water

All three steps must be completed in full. The appliance is 

ready for operation again only after the 2nd rinse.

Descaler

Only use the liquid descaler recommended by the after-sales 

service for descaling (product no. 311 138, also available 

online from the eShop). Other descalers may damage the 

appliance.

1.

Prepare a descaling solution by mixing 300 ml water and 

60 ml liquid descaler.

2.

Empty the water tank and fill with descaling solution.

Caution!

Risk of surface damage: If descaler comes into contact with the 

front of the appliance or any other sensitive surfaces, wash it off 

immediately with water.

whole appliance, but only the evaporator dish in the cooking 

compartment.

20 ml liquid descaler.

Fill the water tank with water only.

4.

Start "Descale" as described.

You can also descale the evaporator dish manually.
