6) No water at all.
Cause: Valve incorrectly fitted.
Debris in the mains.
Mains water supply turned off.
7) Grey metallic deposit in the water
Cause:Corrosion of the sacrificial anode.
(Note: Corrosion of the sacrificial anode is normal operation of the unit)
8) Rapid depletion of the sacrifical anode (see 7)
Cause: Di-electric junctions not fitted
Water softener fitted on incoming supply to water heater
(Softened will cause the anode to deplete more rapidly than hard water)
Note Whilst Ariston do not advise against the use of water softener devices, the
end user must be advised that rapid depletion of the sacrificial anode may
occur as a result of the softened water which can result in metallic grey deposit
in the water.
