connectors
Leaks from heating element
Cures and explanations
Reconnect the lamp and thermostat.
Replace lamp
Reinstate the mains power supply
Reset the thermostat. Call qualified personnel. See notes on "Safety
limiting device"
Check and close any hot water drawing taps even left partially open.
Have a qualified plumber check the plumbing system; a small leak can
activate the heating element often or continuously.
not
Remove the thermostat and check the connectors (thermostat and
heating element). Call qualified personnel.
Check electrical continuity and insulation and replace the heating
element if necessary. Call qualified personnel.
Disconnect any other electrical appliances or call qualified personnel to
replace the heating element
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).
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".
Leaks are generally seen at the bottom of the appliance.
Dripping can occur if the water in the tank is cold. Always check for
leaks with the water hot.
Check tightness
Tighten down and check tightness
Check tightness, replace gasket and tighten securely. Replace the
heating element if faulty.
and replace the gaskets.
