Cause / Rectification
Water container furred. /
Descale water system (see
maintenance).
Drain valve open. / Close Drain
valve.
Drain valve drainage socket
closed. / Check opening for
soiling (slush, ice, leaves etc.)
and remove if necessary.
Water pressure too high. /
Check pump pressure (max.
280 kPa). If the hot water sys-
tem is connected to a central
water supply (rural or urban
connection), a pressure reduc-
er must be used, which will
prevent pressures higher than
280 kPa from occurring.
Hot water flows back
through the cold water
supply. / Fit a non-return valve
in the cold water supply (refer
to installation instructions
"Water connection").
