Safety first: Unplug the appliance. This fault involves high-voltage electronics; only proceed if you are competent with electrical safety.

Step-by-step checks:

Visual inspection of PCB: Remove the control panel or rear cover to access the power module. Look for burnt components, cracked solder joints, or discolored areas.
Check motor windings: Disconnect the motor and measure resistance between windings and to earth. Very low resistance or a short to chassis indicates a faulty motor that must be replaced before fitting a new board.
Inspect connectors: Ensure all plugs to the power module are fully seated and free of heat damage. Clean lightly oxidized contacts.
Module replacement: If the motor tests good but visible damage exists on the board, replace the main control / power module with the exact Balay part number. Transfer any configuration jumpers as per service documentation.
Professional service: If no obvious damage is visible, further diagnosis requires live testing and should be performed by a qualified technician.
