Possible cause
Heating element or internal electrical
wiring is out of order .
Thermostat is set too low .
Heating element or the internal electrical
wiring is partially out of order .
UX mixing valve(fitted on top) is
incorrectly adjusted .
Water expands when heated . If there
is no consumption of hot water over
a period of time pressure builds up,
causing the safety valve to open .
The heating element may not be
properly tightened .
There may be a leak .
Check if there is any power on the power
supply on the connector of the heating
element between black and yellow/
green wires . If this is OK, press the reset
button on the fuse/safety cut-off .
Adjust the thermostat up using a
standard screwdriver .
Check the resistance of the heating
element on the connector of the heater
bundle, and the condition of the internal
wiring .
Adjust the UX mixing valve correctly to
the preferred temperature .
If drip from the SV is severe, it might
need to be replaced . Some dripping
is normal . Alternatively an expansion
vessel can be fitted .
Check the heating element o-ring seal
and all connections .
Contact the installer/supplier regarding
any other failure .
