12 Faulty Wiring

If there is a fault in the wiring, the mixer grinder will turn off automatically. The main reason for this problem is
the poor build quality or long usage of the mixer grinder.

PROCEDURE

• Visual Inspection: Examine the mixer/grinder for any visible defects, such as cracks, loose parts, or signs of
wear.
• Functional Test: Plug in the mixer/grinder and test its functionality. Check if it turns on, spins smoothly, and
operates at different speeds (if applicable).
• Check Power Supply: Ensure that the power outlet is functioning correctly. Test the power cord and plug for
any damage or loose connections.
• Inspect Blades and Accessories: Remove the grinder’s lid or mixer’s attachment and inspect the blades and
other accessories for damage or wear. Replace any worn-out or damaged parts.

• Motor Inspection: Listen for any unusual noises coming from the motor while it’s running. Check for overheating
or burning smells, which could indicate motor issues.
• Electrical Components: If the mixer/grinder has electrical controls, switches, or a speed regulator, inspect
them for any damage or loose connections. Test them using a multimeter if necessary.
• Bearings and Bushings: Check the bearings and bushings for wear and tear. If there’s excessive play or
grinding noises, they may need to be replaced.

• Lubrication: Apply lubricant to moving parts such as bearings, gears, and shafts to ensure smooth operation.
Avoid over-lubricating, as it can attract dust and debris.
• Cleaning: Thoroughly clean the interior and exterior of the mixer/grinder, removing any accumulated debris or
food residue.

Result:Ensuring that the mixer grinder operates correctly and safely after defect rectification helps maintain
compliance with regulatory standards and industry regulations.
