Is your washing machine no longer pumping water out? Has this happened after you’ve just plumbed it into a u-bend under the sink, or have moved house and connected it to the existing u-bend plumbing? If so this article is for you.
The most common causes are –
- The plumbing at the new house drains into a connection on the u-bend under the sink, and a blanking piece has been fitted which needs removing
- Some obstruction, that was already inside the washing machine somewhere has become dislodged and gone into the pump during transit
- A wire has come off the pump during transit or some other damage has occurred
Won’t drain after being plumbed in (especially at a new house)
The plumbing under the sink may have been made "safe": If the house is brand new and no washing machine has been installed before then the plastic connector that you connect the drain hose to should be blanked off. Otherwise any water running into the sink will flood into the cupboard below.
If the house has been lived in before it’s possible the people moving out made the connection safe by refitting the original blanking cap. There could be a rubber or plastic blanking cap inside.
To be fair that’s rare though as few people would think to save the part. The picture shows a typical drain hose connector on a u-bend. The drain hose pushes onto the tapered connector, which is screwed to the u-bend.
Unscrew this connector and check there is no blanking piece fitted either at the end of the tapered shaft, or at the point where the connector screws to the u-bend. Also check for obstructions inside this connector or at the aperture of the u-bend where it connects.
Sometimes a blanking piece needs removing and sometimes the tapered end of the connector needs cutting off.

Pump has some obstruction, that was already inside …
Something like a bra wire, coin or even a nail or screw could have been laid in the bottom of the tub, or settled somewhere in the sump hose and become dislodged in the move finding its way into the pump and jamming it. Check the pump filter, or for obstructions jamming the impeller –
