Washing machine won't drain? Check these before you call anyone

A drum full of grey water and a machine that hums but does nothing is most often one of three things: a blocked filter, a kinked or blocked hose, or a failed drain pump. Two of the three are homeowner fixes. Work in order, and start with the rule that outranks everything: unplug the machine before you put your hands anywhere near its innards.

1. The filter (the usual culprit)

Behind the small hatch near the floor lives the drain filter — the trap where coins, hair clips, lint and the odd baby sock retire. Put a shallow tray and towels down, open the hatch slowly (water will come), and unscrew the filter. Clear it, rinse it, check the recess for debris, and screw it back snugly. Our washing-machine cleaning guide covers this as seasonal maintenance; when a machine stops draining, this filter is where the story usually ends.

2. The drain hose

Slide the machine out enough to see the flexible hose running to the standpipe or under-sink connection. Feel its whole length for kinks; pull it off the standpipe (have a bucket ready) and check for a blockage at the end and in the standpipe itself. Re-fit it at the height the manual states — a hose hanging too low can siphon water out mid-cycle and mimic other faults.

3. Reading the pump's behaviour

Start a drain/spin cycle and listen at the filter hatch. A humming-then-clicking silence: the pump is trying and blocked (recheck the filter recess and the pump impeller if your model exposes it). Total silence where the pump used to chatter: the pump or its electrical supply has likely failed — a repairable part, but that job crosses from maintenance into repair: a technician visit usually earns its fee here, especially since pumps are model-specific parts.

The honest boundaries

Water everywhere means working with bowls and towels, patience, and the machine pulled out only when it is safe and stable. If the door stays locked after a drain attempt, most machines release it a few minutes after power is cut — never force it mid-cycle with water standing. And any job that wants the machine's internals opened beyond the filter belongs to someone who does it weekly.
