To remove stains or soiling from the interior surfaces, use water and a cloth dampened
with a little vinegar or detergent suitable for a dishwasher.
12. Antifreeze protection
When operating in cold environments, e.g. during winter months, pay attention to the fol-
lowing information after each wash cycle to prevent freezing:
Pull the mains plug (20) out of the mains socket.
Turn off the water supply, if necessary, and disconnect the water hose from the water
inlet valve (21).
Empty the water tank as described under "1 1.1. Draining water manually" on page
82.
Allow the water to drain out of the hose and valve (e.g. into a bucket).
Reconnect the hose to the water inlet valve (21).
Remove the filter system (5) on the base of the appliance and collect the remaining
water from the appliance base using a rag or sponge.
Contact customer services or a similarly qualified person if the appliance does
not function due to freezing.
13. Longer periods without use
WARNING
Risk of explosion!
Under certain conditions, hydrogen gas may be produced
in a hot water system that has not been used for two weeks
or more. HYDROGEN GAS IS HIGHLY EXPLOSIVE!
If you have not used the dishwasher for an extended pe-
riod of time, open all hot water taps and allow the water
to flow for several minutes before using the dishwasher.
This releases pent up hydrogen gas from the system.
As hydrogen gas can ignite, avoid naked flames during
this time and do not smoke.
Perform a wash cycle without load.
Pull the mains plug (20) out of the mains socket.
Turn off the water supply before cleaning or empty the water tank (see "1 1.1. Draining
water manually" on page 82).
Leave the appliance door open slightly to prevent potential odours from forming and
preserve the seal.
