Speed Queen TC5 classic-clean top-load washer door or lid will not unlock

The checks in more detail

Wait a couple of minutes and press the cycle button, then lift the lid. If the washer is mid-cycle and you need to open it, press Start/Pause and wait for the lock to release. Do not force the lid, which can break the latch. If the lid stays locked long after the cycle ends, the washer may still be draining or sensing water. Check that the drain hose is not kinked and that the drain is clear, since a washer that has not emptied keeps the lid locked as a safety measure.

Look at the display for a code, since a drain or a lid error holds the lock. Unplug the washer for a few minutes to reset the control, plug it in again and see whether the lock releases. After a power cut, the lock may stay engaged until power is restored and the control checks the basket. If the lid stays locked after a reset, there may be water in the tub, so drain it through the pump or by siphoning, but only when the lid can be opened;

if the lid cannot be opened, the manual describes a manual release of the lid lock, a procedure that depends on the model and that you should follow exactly. A lid lock that does not release may have a failed latch or control, which a technician replaces. Never put your hands in the basket while it is moving. Keep the model and serial number for a service call, and check the warranty, since Speed Queen offers long coverage on some parts.
