Overview
The Midea MDF18A1AST is an 18 inch built-in dishwasher with 8 place settings, 6 wash programs plus heated dry and a 136F sanitize function, sized for kitchens too small for a standard 24 inch model.
It's aimed squarely at apartments and smaller kitchens that can't fit a 24 inch dishwasher, with a stainless tub and mounting brackets to anchor it under the counter. The listing specifically warns against using regular dish soap instead of dishwasher detergent, since that combination causes problems.
- 8 place settings in an 18 inch width
- 6 wash programs plus Heated Dry and Hi-Temp sanitize
- Stainless steel tub
- Mounting brackets to secure it under the counter
Pros and cons
- Fits kitchens too small for a 24 inch dishwasher
- Hi-Temp sanitize cycle suitable for baby bottles
- Mounting brackets keep the unit from shifting during a cycle
Performance notes
Six programs cover everything from Quick to Heavy, and the Hi-Temp cycle holds water at up to 136F for sanitizing baby bottles or heavily soiled dishes, backed by a heated dry function on most cycles. Only dishwasher-specific detergent should go in it; the manufacturer notes regular liquid dish soap causes problems.
