Overheating protection 240 V
The operation of the overheating protection 240 V indi-
cates a possibly dangerous situation. Do not reset the
overheating protection 240 V until the water heater has been
serviced by a qualified person.
The 240 V heating facility has a mechanical overheating
switch. If the 12 V power supply is interrupted during opera-
tion or during the after-run period, for example, the tempera-
tures within the unit could activate the overheating protection.

Troubleshooting guide (water supply)
Fault Cause / Remedy
Water taking an extremely
long time to heat up.
Water container furred./
Descale water system
(see“Maintenance”).
Water running out, cannot fill
hot water system.
Drain valve open. / Close drain
valve.
Cannot empty hot water sys-
tem, even though drain valve
is open.
Drain valve draining con-
nection blocked. / Inspect
opening for blockages (slush,
ice, leaves, etc.) and remove
blockage if necessary.
Water dripping/flowing from
draining socket of drain
valve.
Water pressure too high. /
Check pump pressure (max.
280kPa). If connected to a
central water supply (rural or
urban connection), a pressure
reducer must be used, which
will prevent pressures higher
than 280 kPa entering the hot
water system.
When opening the cold wa-
ter tap, hot water comes out.
Hot water flows back through
the cold water supply. / Fit a
non-return valve in the cold
water supply (refer to instal-
lation instructions “Water
connection”).
If these measures do not rectify the fault, please
contact the nearest Leisure-Tec Service Centre.
