Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: GDT670S*
What that covers: GE/GE Profile dishwasher; Dry Boost, bottle jets, UltraFresh and Wi-Fi equipment varies.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Drying — Dry Boost: Dry Boost fan-plus-heat active drying, good on plastics when enabled. Rinse aid helps.
Wash & racks: Stainless tub and a 3rd rack; bottle jets on some builds. A manual filter must be cleaned periodically.
Drain path: 'Won't drain' is usually the filter, drain hose, air gap, or an un-removed disposer knockout plug.

Exact questions

Questions that only have an answer for the GE GDT670 dishwasher

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

My GE GDT670 has a film on glasses.+

Film is usually hard water and rinse aid. Fill and raise the rinse-aid dosage, and in hard-water areas run a dishwasher cleaner/descaler periodically and consider a detergent with a built-in softener. A cloudy etch that will not wipe off can be permanent glass etching from too much detergent plus soft water — reduce detergent. Make sure the water is hot and the filter is clean, too.
