DIAGNOSTIC
14.5. - Troubleshooting advice (IX3, IX3WR and IX4000)
It is difficult to supply a troubleshooting chart since causes are numerous. Within the framework of an
After-sales Department action, the reasoning will be limited to identify which of the components
(Control board, filter board, keyboard, inducer, fan …) is faulty without trying to act on the component
itself (Replacement of components).
Achieving a correct component relies on the use of the test keyboards
available at B.C.S.'s
For each case of failure, it will be advisable to ask the appropriate questions
and use the test points provided by this document to answer them.
Control dysfunction
Æ Systematic use of the test keyboard (two references)
Control dysfunction with the test keyboard
Æ Is the filter board powered? (IX3 and IX3WR)
Æ Is the power board powered?
Æ Is the power relay (located on filter board) controlled? (IX3 and IX3WR)
Æ Does the power relay (fan start-up) switch on ? (IX3 and IX3WR)
These checks are used to determine which of the 'filter' or 'power' boards is out of order.
Ventilation dysfunction
Æ In case of ‘overheating error' message, check if the installation is correct ?
Æ Is the fan mechanically locked?
Æ Is the fan powered? (12VDC or 230VAC according to model)
In event of dysfunction on only one inducer
Æ First, check the connection between power board and inducer.
Æ Is the distribution relay controlled (Clic-Clac)? (IX3, IX4000)
Æ Is there a lock-on problem on one of the sources? (IX3WR, IX6)
Recall: The ‘inverter and detection’ staged is backed-up on IX3WR and IX6 boards.
In event of saucepan non-detection
Æ Does the saucepan pass the magnet test?
Æ Does the saucepan appear in the ‘Class induction’ list?
Æ Does the saucepan have the required minimum diameter (12cm, generally)?
