DESCALING
Depending on the water hardness of your tap water, you should descale the coffee
maker regularly (at least monthly). We recommend the Gastroback Premium Desca-
ler. Alternatively, you may use a solution of 200 ml white vinegar and 800 ml clear
tap water. For further information feel free to contact the Gastroback customer ser-
vice, Tel.: (+49) 4165 / 2225-0.
CAUTION
– Do not use any unsuited descaling agent, because this could
damage the appliance. Only use a descaling solution, suitable for coffee makers.
1. Clean the coffee machine according to the instructions above.
2. Prepare 1.0 litre descaling solution according to the instructions given by the
vendor. Fill the descaling solution into the water tank and leave it within the
