Not listed, and why
- GE Appliances dishwasher H2O: No official GE Appliances support page for a dishwasher H2O code could be located via searches restricted to geappliances.com and products.geappliances.com on 2026-10-16, repeated 2026-10-17; every result was a third-party repair site. The brief for this site forbids building a page from anything but the manufacturer's own page, so no H2O page exists here. Re-check before adding.
Model-specific pages (for example a single washer model number plus a code) are deliberately not built yet. The methodology page explains the review that has to happen first.
