How can I fix an E2 error code on my TCL washing machine by checking the drain hose?

First, unplug the washing machine. Locate the drain hose (usually at the back of the machine). Check for kinks, bends, or obstructions. Detach the hose from the drain pipe and inspect for blockages like lint, socks, or other debris. Flush the hose with water to clear any obstructions and ensure it's properly reconnected without kinks.
