Faults
The guarantee does not cover the above repairs.
If there is a fault in the appliance (the heater does not work and all the above reasons
do not occur), contact the nearest authorised service.
In case the unit does not heat the water, check for possible reasons:
Fault Reason
control lights off power supply failure
unit doesn’t heat up the wa-
ter/ water temp. is too low
power supply failure
water ow rate is too low (e.g. lter is blocked with
impurities)
Technical data
The minimal resistivity of water at 15
0
C for PPH2 and KDH2 is 1100 Ω cm.
