Samsung washing machine repeatedly cracking drain pump magnet

The problem

A Samsung washing machine has had its drain pump DC31-000 replaced twice in two months. On both failed pumps, the motor magnet was found cracked and expanded, which caused the pump to seize. The original pump had lasted six years.

Likely cause

The accepted reply suggested that a foreign object inside the machine may be striking and damaging the pump, for example a coin or other metal item. This was suggested as a possible cause, not confirmed.

What fixed it

Check the drain pump and associated sump/drain path for foreign objects that could contact the pump and damage it. The discussion does not confirm an exact repair beyond this diagnosis.

Checks to try

• Drain pump removed and replaced twice
• Motor taken apart and magnet found cracked and expanded
• Suggested check for an object stuck inside the machine, such as a coin or other metal item
