Hello everyone, we have this circuit board that belongs to a water bath (GFL 1005 model), duo to lack of water in it while its still on, the water bath stopped working. now we are trying to fix the thing ourselves.
when we opened the water bath up this was the circuit and where now you can see the blue circle there a piece that is missing. can anyone help us to find out what that missing piece might be? (we did not find any blueprint for this board online)


in the next pic we replaced MOC3043 with MOC4041, can we do that? and will it effect the device in any way??

 

If you have an opto triac, then there should be a triac somewhere.
