How to Disconnect a Washing Machine (Without Flooding the Kitchen)

Updated July 2026 · Emergency Plumber Chelsea

Before you start, gather a shallow tray or baking tin, a bucket, several old towels, a pair of adjustable grips and a torch. If you are removing the machine for good, have a blanking cap ready for the water valve and a cap or bung for the waste connection, both available from a plumbers' merchant or DIY shop. Make sure the machine has finished its last cycle and has had time to cool, because the water inside can still be hot after a wash.

Start by switching the machine off and unplugging it. Pull it out from under the worktop slowly, lifting the front feet slightly if it sticks, and stop as soon as you can reach behind it. Do not yank it out, because the fill hose, waste hose and power cable are all still attached and are usually only just long enough. In Chelsea kitchens and utility cupboards the machine is often in a tight space under a worktop or behind a door, so it can help to have a second person steadying it.

Next, turn off the water supply to the machine. Behind it, or in the cupboard under the sink next door, you will find one or two small isolation valves where the fill hoses connect to the pipework. Most washing machines only have a cold supply, but older machines and some in period properties still have a hot supply as well. The common type has a blue or red lever. Turn the lever a quarter turn so it sits across the pipe rather than along it, and the water is off. Some valves have a slot for a flat screwdriver instead, and the same rule applies: slot across the pipe is off. If you cannot find a valve, or it will not move, turn off the water at the main stopcock instead. Our guide on which way to turn a stopcock off shows where to look.

Now drain the water left in the machine. Most front loaders have a small hatch at the bottom of the front panel with a filter and, on many models, a thin drain tube. Lay towels down, put your tray underneath, pull out the tube and remove its cap, and let the water run out a little at a time. There can be more water than you expect, so be ready to cap it and empty the tray several times. Once it stops, unscrew the filter slowly to let the last of it out and clear any fluff or coins. The waste hose will also hold some water, so keep the bucket handy for the next step.

To disconnect the fill hose, put a towel under the valve and unscrew the hose connector anticlockwise by hand. If it is tight, use grips gently, holding the valve still with your other hand so you do not twist the pipework. A small amount of water will come out as the connector loosens, which is normal because the hose is still full. If water keeps flowing rather than dribbling to a stop, the valve is not fully closed or has failed. Screw the hose back on, turn off the main stopcock and deal with the valve before going further.

The waste hose connects in one of two ways. In many kitchens it is simply hooked into a standpipe, a vertical pipe with an open top, and you just lift it out and hold the end in the bucket to drain. In others it is connected to a spigot on the sink trap or waste pipe under the sink and held by a jubilee clip or a push fit. Loosen the clip with a screwdriver and pull the hose off the spigot, keeping the end low over the bucket. Some hoses are held to the back of the machine with a plastic hook or clip; leave this in place if the machine is going with you.

Once both hoses are off, seal up what is left behind. If the machine is coming back or a new one is going in soon, the closed isolation valve is fine on its own, but check it for drips after an hour. If the machine is being removed for good, fit a blanking cap onto the valve outlet so a knocked lever cannot flood the floor. On a sink spigot, fit a cap or bung, because an open spigot will let water out when the sink drains and can let drain smells back into the kitchen. An open standpipe should have its trap left in place, but it is sensible to cover the top loosely.

If you are moving the machine, secure the drum with transit bolts before it goes anywhere. These are the long bolts that were fitted at the factory and removed when it was installed. If you kept them, screw them back into the holes on the back panel. If you did not, replacements for your model are easy to find, and moving a machine without them can damage the drum's suspension. Keep the machine upright, tape the door shut, and put the hoses inside the drum so they are not lost.

A few problems crop up regularly. Isolation valves that have not been touched for years often seize, and forcing the lever can snap it or make the valve start weeping round the spindle. Compression nuts on old copper pipework can loosen when you work on a hose next to them. Standpipes that were slow to drain may overflow when you empty the hose into them, which usually means there is a partial blockage further down. If any of these happen, turn the main stopcock off and call. Our guide to washing machine plumbing problems covers leaks, slow draining and valve faults in more detail.

If you are fitting a new machine rather than taking one away, it is worth replacing an old or stiff isolation valve at the same time. Emergency Plumber Chelsea can disconnect and reconnect washing machines and dishwashers, replace seized valves, fit new standpipes or waste connections, and sort out leaks, as part of our kitchen plumbing repairs and minor plumbing work across SW3, SW10, Knightsbridge, South Kensington and Fulham.

Quick tips

• Turn the isolation valve lever a quarter turn so it sits across the pipe; that is off.
• Drain the machine through the filter hatch at the front before you touch the hoses.
• Hold the valve still with one hand while you unscrew the fill hose, so you do not twist the pipe.
• Cap the valve and the sink spigot if the machine is going for good, to stop leaks and drain smells.
• Refit the transit bolts before moving a machine, or the drum's suspension can be damaged.
