The short answer
On a Danby washer, why the water will not leave the drum comes down to a short list, and on this line the order is not the generic one. The diagnosis starts at a blocked pump filter or a jammed impeller, because every coin, hairpin and button in the machine ends up here, and it is the designed collection point for exactly that reason. The first three checks below need no tools and no parts; the point at which this stops being an owner job is stated further down, as a condition rather than as a recommendation.
What you are seeing
- The drum is full of water at the end of the cycle.
- The machine will not spin because it has not emptied.
- The pump runs audibly but nothing leaves.
- The machine drains slowly and the sink backs up.
- Water drains and then returns to the drum.
- The cycle stops partway with a drain error.
- Note: Near-miss symptoms that mean a different fault: If water is on the floor rather than in the drum, that is the leak page. If the machine will not start at all, the drain is not the first place to look. A little water left in the boot of a front-loading machine is normal.
Causes, ranked for a Danby washer
- A blocked pump filter or a jammed impeller — Why this rank: Every coin, hairpin and button in the machine ends up here, and it is the designed collection point for exactly that reason.
- A drain hose too high, too low, or pushed too far into the standpipe — Why this rank: On a portable machine the hose is repositioned every wash, and both extremes stop the machine draining properly.
- The wrong platform assumed at the start of the diagnosis — Why this rank: The Danby badge covers several unrelated platforms, so a large share of wrong turns here begin with a manual-defrost cabinet being treated as a frost-free one, or a portable machine as a plumbed-in one.
- A kinked or crushed drain hose — Why this rank: It is the part most often trapped behind the machine when it is pushed back against a wall.
- A slow or blocked sink or standpipe — Why this rank: The machine empties faster than a partly blocked drain accepts, so the water comes back rather than going away.
- Siphoning because the hose sits below the water line — Why this rank: It empties the drum continuously during the wash and then reads as a drain problem at the end.
What to check, in order
- Open the pump filter access at the front bottom over a shallow tray and see what comes out. — Order: First — Why: It is the top cause by a wide margin, it needs no tools on most machines, and it is where the machine is designed to collect debris.
- Listen at the drain phase — a humming pump that moves nothing is jammed, a silent one is not running. — Order: Second — Why: That single distinction separates a jam from a failure and decides whether a part is needed.
- Follow the drain hose from the machine to where it discharges and check its height and its route. — Order: Third — Why: It is the second cause and it is entirely visible.
- Run the sink or the standpipe on its own and confirm it takes water quickly. — Order: Fourth — Why: It separates the household plumbing from the machine in a minute.
Steps a homeowner can take
- Unplug the machine or switch off its breaker before opening the pump filter or removing a panel. — Tools: none — Time: a moment
- Place a shallow tray and towels under the filter access, open it slowly and let the water out in stages. — Tools: shallow tray, towels — Time: half an hour or so
- Remove the filter, clear the debris, check the impeller turns freely by hand, and refit the filter fully. — Tools: gloves, flashlight — Time: half an hour or so
- Straighten the drain hose along its whole length and check nothing is standing on it. — Tools: flashlight — Time: several minutes
- Set the drain hose height to the range in the manual and secure it so it cannot slip in or out. — Tools: cable tie, tape measure — Time: several minutes
- Run the sink or standpipe on its own and clear its trap if it is slow. — Tools: bucket, wrench — Time: half an hour or so
Before you start
Safety
Unplug the appliance or switch off its breaker before opening the pump filter or removing a panel. A capacitor can hold a charge after the power is off. The drum may hold hot water — open the filter slowly and in stages, with towels down. Never reach into a pump housing without confirming the machine is isolated.
When this stops being an owner job
Call when the filter and impeller are clear, the hose is straight and correctly positioned, the household drain is proven and the machine still will not empty. What remains is the pump itself or the level sensor, and both are behind the cabinet.

Generalized information
This page is generalized: it covers Danby across the whole washer range rather than one family or one model group. It does not cover the Danby Designer, Danby Premiere and Danby One Plug sub-lines and their model-level pages, which do not exist in this reference yet; when they do, they will be linked from here. Until then, check the rating plate for your model group before ordering any part, because that is what the ranking above cannot narrow for you.
