Why is a hidden heating element important on the DW80J3020US?
The hidden heating element reduces the risk of melting plastic items placed in the dishwasher. It also aids in the drying process, as the stainless steel interior retains heat better than plastic tubs, allowing dishes to dry faster. (Page 1)
