Are Dishwashers with Plastic Tub Safe or Not?

The only big disadvantage of a plastic dishwasher tub is that it consumes more electricity for which it is not recommended over a stainless steel one.

As you know plastic is very soft and cannot bear large heat. If over-heated it will be melted.

During the drying process in the dishwasher, heat is used to dry the dishes that are washed. If the temperature is high these will be dried quickly and there will be less consumption of electricity during this process.

But plastic cannot do this. It can neither bear nor retain large heat. At low heat, it takes a lot of time to wash dishes that increase your electricity bill.

The other disadvantage of the plastic dishwasher is that it has not the ability to absorb the noise of washing dishes.

New plastic dishwashers have some extra layers to prevent heat loss but still, they cannot absorb much of the noise and you have to face noise while washing your dishes.

Plastic dishwashers also have some advantages over steel dishwashers.

You can get them at a low price and these do not catch stains reducing your effort for washing them.
