9.1 Fault Finding
9.1.1 Important
• Servicing should only be carried out by competent persons
in the installation and maintenance of unvented water
heating systems.
• Any spare parts used MUST be authorised Baxi Genuine
Parts.
• Disconnect the electrical supply before removing any
electrical equipment covers.
• NEVER bypass any thermal controls or operate system
without the necessary safety valves.
• Water contained in the cylinder may be very hot, especially
following a thermal control failure. Caution must be taken
when drawing water from the unit.
The fault finding chart (table 4, below) will enable operational
faults to be identified and their possible causes rectified. Any
work carried out on the unvented water heater and its
associated controls MUST be carried out by a competent
installer for unvented water heating systems. In case of doubt
contact service support.
Warning
Do not tamper with any of the safety valves or controls
supplied with the cylinder as this will invalidate any
guarantee.
