A:Answer Hi Lou,
Thanks for your question. There are a few possible explanations for what you're experiencing with your DW80J7550UG Dishwasher involving such factors as water pressure and temperature, or the drain hose may not be routed correctly. I'd suggest reviewing the information on pages 29-30 of the User Manual (see advice for particles left on dishes and film in dishwasher), and on page 19 of the Install Guide (see Figure 12 on that page in particular). In addition, it may be time to clean the filter (see page 26 of the User Manual).
Thank you,
Ms. Samsung
