| + | [* black] Shows the inside working of the lock. It was fairly easy to disassemble (4 plastic clips and 5 screws). It is not necessary to do this, but gives an understanding of what is happening. |
|---|---|
| + | [* black] The adjusting screw is directly below the heater so is not shown. |
| + | [* black] The power line heats up the heater which in turn heats and bends the bimetallic spring. This pushes up the pivoted lever which pushes down the flip flop switch. If there is too much slack in the system, the lever wont push the switch down quite enough to trigger it. (Thumping the machine probably gave it enough movement to trigger the switch). |
| + | [* black] Slack in the system was decreased by moving the heater assembly up using the adjustment screw. |
| + | [* black] When the switch is triggered, the electrical contacts close, sending a message to the rest of the machine that it is safe to turn on. Triggering the switch also moves the black timer lock which physically restrains a slider mechanism. ( the silver water lock also restrains this slider but this was working fine and not altered) |
