This article is for if you’ve just plumbed a washing machine into a u-bend under the sink, or have just moved house and connected your washing machine to the existing u-bend plumbing under the sink and your washing machine doesn’t pump out (but it did before). Make sure that the connector that you fit the drain hose onto doesn’t have a blanked end which needs cutting off, or a blanking piece in the connector which needs removing.
The most common faults 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
- A wire has come off the pump during transit or some other damage has occurred
Buy a new pump

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.
The picture above 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.
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 –

Hi my question is largely based on this as last year we had a new kitchen fitted and a washing machine MOVED. It is now currently taped into the ubend and has fits where it either doesn’t rinse OR doesn’t spin well! Due to both things happening at the same time plus the fact the washing machine was a refurb newby to the house too I have no idea where to start to fix the issues cos the machine seems to have a mind of it’s own and can keep soap for 3 cycles on the run (if not double it) but has no rinse cycle (just spin) and only seems to behave on ‘cotton intensive (2 hours long) how do I go about troubleshooting this..please help we’re a family of 5, 3 children at school, 4 of us suffer with very dry skin and I can’t keep ‘washing’ every load 4 times to get rid of soap! It’s a Curry’s basics washing machine I think (no brand and for the first 2 weeks we had it it worked like a dream!!) Currently watching the end of a synthetics wash (3rd time lucky NOT) no soap since3 first wash and the drum is still full of soap (and yes it quite often doesn’t spin the water out either like I said broadly based question!) starting to wish I had a big pond w
ith lots of stones right now!
