Wet plastics versus a dishwasher that no longer dries well

Look at the pattern across the finished load. Are glass and ceramic items dry while plastic lids hold droplets, or has drying changed for everything? Thermador explains that plastics can dry less readily in condensation drying. The result should be compared with the same program and similar items, not only with a previous dishwasher of another design.

Check the selected program and any drying options in your model manual. Observe the rinse-aid indicator and whether cups or containers were loaded in a way that collects water. These are owner-use details; they do not establish that heating or a drying component has failed. Do not add hand dish soap or improvised chemicals.

If performance has changed noticeably on familiar loads, record whether washing is also worse, a program ends early or a message appears. Explain whether the concern is droplets, pools in upturned bases or a film left after drying. Each description gives the technician a different starting point and can prevent a drying complaint from being confused with poor cleaning.

Useful observations before you call

• Compare plastics with glassware from the same completed cycle.
• Note the program, optional drying setting and rinse-aid indication.
• Photograph the loading arrangement and result before rearranging the dishes.
