What does Speed Queen error code ALArn mean?
ALArn is a security message on the Speed Queen/Alliance topload washers covered by the TLW13C troubleshooting manual. The display text is "Break-in Alarm Error," and the error code listing says the door or coin vault switch reported an opening that was not allowed. The principle is simple. The washer has switches that watch the lid or door and the coin vault, and if one of them opens when it should not, such as while the vault is locked or between cycles, the control records it as a possible break-in and shows ALArn. The manual lists no causes and gives one action: service the door or coin vault switches. It does not say whether the washer can still run, how the alarm is cleared, or what counts as an allowed opening. The reason a switch triggers is not always a break-in. A switch that has moved out of position, a damaged vault door or a loose connector can produce the same report, so the first job is finding out whether anyone actually opened the machine.
