BEFORE YOU BEGIN

Before you begin. This procedure is general reference information, not professional advice. Equipment varies by manufacturer, model, and year. Always follow the documentation supplied with your equipment — where it differs from this page, follow the manufacturer. Verify that you have the tools, the working conditions, and the ability to do this task safely. If anything is unclear, if the equipment is damaged, or if the task exceeds your experience, stop and use a qualified professional. You are responsible for your own safety and for the outcome. This site accepts no liability for any loss, damage, or injury arising from the use of this information.

Specifications marked unverified could not be traced to a manufacturer source. Do not rely on them — obtain the value from your equipment documentation.

Summary

A dehumidifier with a continuous drain lets it run for days without you emptying the bucket, using either gravity through a garden hose or a built-in pump. The most common reason a connected drain hose still leaves you emptying the bucket is not a broken machine: it is a hose with a high point, a kink, or a clogged drain port, all of which stop the water from leaving. This page walks you through connecting a gravity drain hose or a built-in pump drain hose for the first time, and through finding and clearing the blockage when a hose that used to work has stopped.

What this page will not do is hand you one hose thread, one maximum hose length, or one pump lift height that fits every dehumidifier, because manufacturers do not agree and the fitting differs by model. Danby's own owner's manual gives real numbers for its own gravity-drain models, printed here with that source, and Frigidaire and GE Appliances both publish their own troubleshooting steps for a pump model that will not drain. Check the installation instructions for your own model before you buy a hose or extend one upward. If a fault code stays on the display after you clear the hose, or if water keeps collecting on the floor, this page tells you where to stop and who to call.

Safety

WARNING

DISCONNECT THE DEHUMIDIFIER FROM THE POWER SUPPLY BEFORE YOU CONNECT, ROUTE OR CLEAR THE DRAIN HOSE.
Water near the power cord can give you an electric shock.

WARNING

STOP THE DEHUMIDIFIER IF YOU SEE SMOKE OR SMELL BURNED PLASTIC NEAR IT.
Disconnect the dehumidifier from the power supply and contact the manufacturer.

Recall notice

NOTICE

U.S. Consumer Product Safety Commission 23-262

On 16 August 2023 the CPSC announced the recall of about 1.56 million Gree-made dehumidifiers, sold under the Kenmore, GE, SoleusAir, Norpole and Seabreeze brands and manufactured between January 2011 and February 2014. The notice states that the dehumidifiers can overheat, smoke, and catch fire, posing fire and burn hazards, and reports at least 23 fires, 688 overheating incidents and $168,000 in property damage. Consumers are told to immediately stop use, unplug the dehumidifiers, and contact Gree for a refund. If your machine is old, check its model number against the CPSC list before you work on its drain.

When to use a professional

If a fault code stays after you clear the hose and reconnect the dehumidifier, contact the manufacturer.

If water still collects on the floor after this check, contact the manufacturer or a qualified appliance technician.

Do not raise the pump hose above the maximum lift your own documentation gives. Contact the manufacturer if you cannot find this figure for your model.

Find your model number on the CPSC recall list before you work on an old dehumidifier.

Common questions

Why does my dehumidifier's bucket still fill up even though I connected a drain hose?

The most common cause is a hose that rises above its starting point somewhere along its run, because a gravity drain moves water only downhill and any high point traps it. A kink, a squashed section, or a clogged drain port inside the appliance can also stop the flow completely. Danby's own troubleshooting guidance for its gravity-drain models names a loose hose connection and a removed drain cover as causes of water on the floor instead of in the hose. Check the full length of the hose for a bend before you assume the appliance itself has failed. If your model has a built-in pump instead of a gravity drain, a blocked pump inlet or a poorly seated bucket can cause the same symptom.

What size hose do I need for a continuous drain?

It depends on your model, and this is one of the numbers this page will not generalize for you. Danby's own owner's manual for its DDR020BJWDB-ME, DDR030BJWDB-ME, DDR040BJWDB-ME and DDR050BJWDB-ME models calls for a standard garden hose with an inside diameter of at least 5/16 inch, and gives a maximum hose length of 1.8 m (6 ft) for those specific models. Your own model's installation instructions give the fitting and the length that apply to your dehumidifier. A hose that is longer than your manufacturer allows can leave standing water inside it.

Can my continuous drain hose run uphill?

Not if your dehumidifier drains by gravity alone. Danby states plainly that its continuous drain is fed only by gravity, and that any bend or upward run in the hose stops the water from draining. A dehumidifier with a built-in pump can move water up and away from the appliance, but only up to the maximum lift height your own documentation gives for that pump. Check whether your model has a pump before you plan the route for the hose.

Does my dehumidifier need a floor drain nearby?

A floor drain is the simplest destination for a continuous drain hose, but it is not the only one. Danby's own instructions say to direct the free end of the hose to a floor drain or to a large container instead. Whatever you choose, the container or the drain must sit lower than the drain outlet on the back of the appliance for a gravity model to work.

Why did my drain hose freeze or slow down in cold weather?

Frost can form inside a dehumidifier when the room temperature drops low enough, and Danby's own manual notes this can happen below about 5°C (41°F). The appliance defrosts itself automatically, and the compressor stops for a while as the fan keeps running. If the room stays cold, ice can also form inside the drain hose itself and block the flow of water until it thaws. Move the dehumidifier to a warmer space, or wait for the room to warm, before you assume the hose or the appliance has failed.

My dehumidifier shows a fault code even though I connected the drain hose. What now?

A fault code such as PU, P1 or E01 usually points to the pump or the drain hose on a pump model, but the exact letters and the correct response differ by manufacturer and even by model within the same brand. Frigidaire tells owners with a PU code to check that the pump drain hose is well connected and free of a kink, a blockage or ice. This page does not repeat a full fault code table; a separate page on this site indexes the codes that several manufacturers publish for their own machines. Clear the hose using the steps here, reconnect the dehumidifier, and check whether the code returns.

Revision history

  1. v1 · 2026-08-04First draft. Sourced to Danby's own owner's manual for its DDR020BJWDB-ME/DDR030BJWDB-ME/DDR040BJWDB-ME/DDR050BJWDB-ME gravity-drain models (thread and hose dimensions, gravity-only operation, drain port cleaning, frost behaviour), and to Frigidaire and GE Appliances pump-model troubleshooting guidance. The female-end thread notation in the Danby manual ('ID:M=1') was not decoded and routes to the manufacturer rather than being guessed. Pump lift height routes to the manufacturer on every model, because neither source read for this page states one. Carries CPSC recall 23-262 because the recalled population overlaps the machines this page is about.

Corrections to this page are listed in the public corrections log. Reports that are credible and not yet verified are listed in the public errata register, and an open one renders above the step it concerns.
