The short answer
A Speed Queen washer that will not drain is usually blocked outside the machine rather than broken inside it. These are simply built, robust machines, so the drain hose, the standpipe and a foreign object account for the great majority of drainage complaints, and the pump itself is the last suspect rather than the first.
Causes, ranked for this Speed Queen washer
- Drain hose kinked, crushed or too low — Why: A hose pinched behind the machine stops the drain completely, and one set too low into the standpipe siphons continuously, so both ends of this complaint start with the same hose.
- Standpipe blocked or silted — Why: Lint and detergent silt a standpipe over years until it backs up, which puts water on the floor and stops the machine draining without any appliance fault.
- Foreign object in the pump or hose — Why: Coins, buttons and hair clips reach the pump and either lodge in the hose or jam the impeller, which gives a hum with no flow or complete silence.
- Household drain restricted — Why: A washer discharges a lot of water quickly, so a partly blocked house drain backs up under that flow while a sink draining slowly seems fine.
- Drain pump failed — Why: Last, because a silent pump is far more often jammed than dead, and every cause above is checkable without opening the machine.
What to check, in order
- listen at the drain step for whether the pump runs at all. — Because: a running pump with no flow is a blockage; silence is a jam or a failure.
- trace the drain hose for kinks, crushing and its height at the standpipe. — Because: it is the top-ranked cause and it costs nothing to correct.
- check whether water backs up out of the standpipe. — Because: that moves the fault into the household plumbing entirely.
- check the pockets habit and look for an object in the hose. — Because: a coin is a common and completely avoidable cause of a stopped drain.
Checks you can safely do yourself
- Unplug the machine, then bail or siphon the tub down enough to work safely. — Tools: a bucket and a jug — Time: the better part of an hour
- Pull the machine forward and trace the drain hose along its whole length for kinks and crushing. — Tools: a torch — Time: several minutes
- Check how far the hose is inserted into the standpipe and set it to the height your manual specifies. — Tools: the owner manual — Time: several minutes
- Disconnect the hose over a bucket and check whether water runs freely from the machine and whether the standpipe accepts water. — Tools: a bucket — Time: several minutes
- Feel through the hose connection for an obstruction near the pump. Stop here: opening the pump housing is service work. — Tools: gloves and a torch — Time: several minutes
Before you open anything
Safety
unplug-before-service
Unplug the machine before disconnecting any hose and expect a substantial volume of water, so work with a bucket and cloths ready. The water may be hot after a warm wash, so let it cool. Do not stand in water while reaching behind the machine.
Where the owner fix ends
Bailing the tub, correcting the hose and clearing the standpipe are owner work. Call a technician when water runs freely from a disconnected hose but the machine still will not drain, since the pump is what remains; and call a plumber when the standpipe backs up with the hose disconnected.
