LG WM14311FD OE fault with grinding noise and no drain after pump issue

The problem

LG WM14311FD washing machine originally showed OE, made a grinding noise and would not drain or spin. On inspection the drain pump impeller had come off. After fitting a complete replacement for that pump, the machine then stopped at the drain stage with the time counting down, and no new error code was reported.

Likely cause

The thread supports a drain system fault. The accepted reply states that if an impeller has come off it is usually broken and the pump should be replaced complete. A later reply says that if it still is not draining, the drain path should be checked for blockage; if it is draining but still showing OE, a blocked pressure system is possible. The second pump was identified as the recirculation pump and was not considered likely to stop normal draining.

What fixed it

Replace the complete drain pump rather than attempting to reuse or refit a detached impeller. If the machine still does not drain afterwards, check the drain path for blockages. If draining is actually normal but OE remains, the pressure system may be blocked. The exact final repair was not confirmed in the discussion.

Checks to try

• Observed OE fault code
• Grinding noise reported
• Machine not draining or spinning
• Drain pump impeller found detached
• Complete replacement of one pump carried out
• Second pump noted to make slight noise but turn intact
• Advice given to check for drain blockage
• Advice given that a blocked pressure system is possible if OE remains despite draining
