No, submerging the electric frying pan is not recommended.
In the case of an electric frying pan, submerging it in water will cause damage to the electrical power cord and to the heating element.
This may also cause water to leak into the appliance’s inner workings and then become plugged up with food particles.
If one does choose to submerge their electric frying pan, they should remove it before it is fully submerged and eliminate the risk of water seeping into its inner workings.
