Technical Information Update: Flood Affected Bosch Water Heaters
In order to address safety and
service issues as a result of the current flooding of properties in various
areas of Australia, Robert
Bosch (Australia)
Pty Ltd would like to advise the following.
ALL REPAIRS
OR MAINTENANCE MUST BE PERFORMED BY A FULLY QUALIFIED, LICENCED
PLUMBER/GASFITTER.
ELECTRONIC
UNITS
Where there is an indication the
water heater has been fully or partially submerged, any Bosch unit with
connection to 240VAC power supply is deemed beyond repair and should be
replaced. It is not advisable to attempt repair of these units as they may be
left in an unsafe condition, even after
repair.
MECHANICAL
INSTANTANEOUS UNITS
The gas regulator is required to be
replaced prior to attempting repair on the mechanical instantaneous units.
Where there is an indication the
water heater has been fully or partially submerged, this type of unit may be
repairable* by a complete service including cleaning and drying of all components.
This
function should and can only be performed by a licensed and suitably trained
person.
Battery and Hydro Models
(No connection to mains power supply)
As there is the danger of ingress of
dirt and moisture to all parts of the appliance, it is strongly advised that the gas burner, pilot burner, and gas
valve be disassembled, cleaned, lubricated (where applicable), and checked for
correct operation.
Pilot
Models
As there is the danger of ingress of
dirt and moisture to all parts of the appliance it is strongly advised that the gas burner, pilot burner, and gas
valve be disassembled, cleaned and lubricated (where applicable) paying
particular attention to the magnetic valve assembly - it should then be checked
for correct operation.
In all cases it is recommended that
after servicing has been performed the appliance is checked for correct
operation, the appliance is gas tight with no leaks of either gas or water, and
gas pressures to the appliance & burner are checked & adjusted to
specification.
*The
decision to repair or replace remains with the attending licensed
plumber/gasfitter.
