If an error code indicates a water-related issue (code Er or dr, Er or FL, Er or nF, or Er or OF), check hot/cold water faucets and fill hoses, clean water mixing valve screens and filter screens, and unplug the machine for 15 seconds to clear the code. If the issue persists, clean any foreign object traps in the pump and check for drain errors. Contact Speed Queen customer service for assistance if necessary.
