A:Answer Hi Dee - Thanks for reaching out to us! Model ADHB50LZ does not have an on/off switch for the water to drain through the hose. When the hose is connected, water will automatically go through it instead of running into the bucket. We suggest viewing page 7 of the manual at the following link for guidance: https://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-5000443-1.pdf - Or, take a look at this link- DEHUMIDIFIER - DRAINING OPTIONS: https://products.geappliances.com/appliance/gea-support-search-content?contentId=35530 - If water does not drain through the hose, check the following link for tips- DEHUMIDIFIER - DRAIN HOSE ISSUES: https://products.geappliances.com/appliance/gea-support-search-content?contentId=16820 - If you have any additional questions, don’t hesitate to ask.
