The Maytag Bravos Quiet Series 300 washing machine has a display. It displays codes sometimes. Is there a list of status codes?
From the Maytag Bravos® Use & Care Guide (PDF)
Code Reason LF Washer is taking too long to fill Ld Washer is taking too long to drain uL Unbalanced load oL Overload Sd Suds detected lid Lid open HC Hot and cold supplies reversed dL Door/lid cannot lock dU Door/lid cannot unlock Fd Factory Default F_ _ Fault code
If the machine is showing one of the fault codes, you'll have to contact Maytag. The list of fault codes is probably not publicly published, and is likely only available to Maytag service people.
