Either the tilt safety switch (“iSbA”) or the magnetic
bowl safety switch (“isCU) is not being detected.
Checks to be made in the following order:
1) Check that the bowl has resumed its vertical
position
2) Check that the bowl is properly locked at the
right angle
3) Check (with an ohmmeter) that the contact of the
tilt switch is closed and check the relevant wiring.
4) Check (with an ohmmeter) that the bowl presence
switch’s contact is closed. If necessary, remove
the bowl and place a sufficiently powerful
magnet close to the magnetic switch. Check the
relevant wiring
5) If the tilt and bowl switches are both closed,
carry out the checks described above for the
"iSbC" and "iSCO" messages.
If all four tilt, bowl, lid arm and lid switches are
closed but this message remains on the screen,
either get the control board checked over or have it
replaced.
