Fault
Possible causes
Cures and explanations
Indicator light does not
come on (hot water comes
out)
Lamp not connected
Reconnect the lamp and thermostat.
Faulty lamp
Replace lamp
Indicator light does not
come on
(hot water does not come
out)
No current
Reinstate the mains power supply
Thermostat safety limiting device
tripped
Reset the thermostat. Call qualified personnel. See notes on “Safety limiting
device”
Indicator light always on
(with little hot water
available)
Drawing tap/s open
Check and close any hot water drawing taps even left partially open.
Leak in system hot water section
Have a qualified plumber check the plumbing system; a small leak can activate
the heating element often or continuously.
Indicator light always on
(hot water does not come
out)
Thermostat connectors not
correctly inserted in heating
element
Remove the thermostat and check the connectors (thermostat and heating
element). Call qualified personnel.
Heating element interrupted
Check electrical continuity and insulation and replace the heating element if
necessary. Call qualified personnel.
Indicator light goes off when
water heater is switched on
Element line overloaded or heating
element earthed causing tripping of
protection device
Disconnect any other electrical appliances or call qualified personnel to replace
the heating element
Electric heating element
noisy
Anomalous level of water
hardness.
Water causing scaling.
Scale on the heating element causes an uneven and violent heat exchange in
the places where it has come off. The definitive solution is to install a water
softener (A dispenser may not be sufficient).
Dripping from water safety
unit
Internal pressure greater than or
equal to 0.7 Mpa (7 bar). (Often
due to normal water expansion
during heating)
The system cannot “absorb” the water expansion in heating. To avoid dripping
install an expansion tank or connect the safety valve to a drain.
See the relevant section “Dripping from water safety unit” and “Expansion tank”.
Water leaks
GENERAL NOTES
Leaks are generally seen at the bottom of the appliance.
Always check for leaks in the SOURCE ZONES indicated below.
Condensation
Dripping can occur if the water in the tank is cold. Always check for leaks with the
water hot.
Hot and cold water flexible
connectors
Check tightness and replace the gaskets.
Tighten down and check tightness
Leaks from heating element
Check tightness, replace gasket and tighten securely. Replace the heating
element if faulty.
Leak from anode cap
Inspect the zone immediately around the anode cap. If wet replace the anode
