This video will show you how to Replace a washing machine door lock or interlock
Your washing machine door won't open this video will show you how to change the interlock.
Washing Machine door switches or (interlocks) come in different shapes and forms but for the most part they work either by the conventional press switch mechanism, operated when the door is closed, this normally incorporates some kind of pressure valve assembly,
To hold the door locked while there is water in the drum, or via a bimetallic strip inside that heats up when an electrical charge is passed through it, causing it to bend and so operate a toggle switch mechanism.
On this type of door lock there is normally a 2 to 5 minutes delay before the mechanism releases, because it takes a short time for the bi-metal strip to cool down if the door will not open then try unplugging the machine from the power and on some washing machine you will need to drain the water out see other video tutorials on this.
