Drain error (heat pump and condensing dryers). The dryer stopped because water can't drain.

Can I fix LG code OE myself?

Start with these safe checks: Empty the water container and push it back in until it clicks. Straighten the drain hose; LG says its top shouldn't be more than 1 meter above the floor and its end shouldn't sit in water. If it still stops, request service.

When should I call a technician for code OE?

If it still stops, request service. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
