Can I fix Whirlpool code Sud myself?

Start with these safe checks: Use only HE detergent and measure it. If you used a thickened "no splash" bleach, switch to regular liquid bleach. Check that the drain hose isn't kinked or clogged. This isn't a fault.

When should I call a technician for code Sud?

This isn't a fault. 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.
