fuse. If the fuse blows again, switch off the device, contact the service
department.
The dispensed water is not cooled,
even though the "Chilled water" but-
ton was pressed The cooling module has not reached its nominal tem-
perature. 1. Wait 20 to 40 minutes and check it again.
If the cooling function exhibits permanent failure:
2. Switch off the device.
3. Contact the service department.
The carbonated water and cold water
buttons light up alternately and a sig-
nal tone can be heard. Temperature regulation fault.  Contact the service department.
The carbonated water button no
longer lights up after 60 seconds and
the dispensing of carbonated water is
blocked. Refilling of the carbonator tank failed. 1. Switch off the device.
2. Check the water supply inlet.
3. Check the gas pressure.
4. Switch the device off and back on again.
5. If the fault persists, contact the service department.

2. If the fault persists, contact the service department.
Too little carbonation in the water The cold water tank has not reached its nominal tem-
perature.  Check the carbonation in the water again after waiting 20 minutes.
The filter is dirty and reduces the necessary water flow. 1. Check the flow of the filter and replace the filter if necessary.

Splashing delivery of carbonated wa-
ter for larger quantities Refilling of the carbonator tank is impaired.  Check the flow of the filter and replace the filter if necessary.
The gas pressure setting is too high. 1. Correct the CO

Time & date Performed
Daily Remove and clean the drip tray.
After an overnight device standstill, dispense 0.5 l of each type of water and dispose of it.
Weekly, more often if neces-
sary Clean the outside of the device, clean the drip tray with hot water or in a dishwasher.
Do not use cleaning agents containing alcohol, acidic components or scouring agents for cleaning plastic surfaces.
Half-yearly If the water quality is bad, replace the Hy-Pure-Plus filter.
Perform chemical cleaning, see chapter
Chemical cleaning .
Annually Replace Hy-Pure-Plus filter.
The decisive factor for the filter change interval is the amount of water dispensed and the water quality of the inlet water.
