What to do if…
your washing machine is leaking and water is spreading across the floor

Short answer

Stop the water at the source (usually the washer’s isolation valves or your inside stop valve) and keep electricity away from the water.

Do not do these things

  • Don’t step into water to reach plugs, extension leads, sockets, the meter cupboard, or the consumer unit.
  • Don’t keep the wash running “to finish the cycle”.
  • Don’t pull the machine out while it’s still powered and leaking (you can rip hoses and worsen the flood).
  • Don’t mop water towards electrical outlets, appliances, or under kitchen units.
  • Don’t plug in fans/heaters or use a hairdryer to “dry it quickly” while the area is damp or electrics may be affected.

What to do now

  1. Get to a safer pause. Keep people and pets out of the wet area (slip + electric-shock risk). Put shoes on if you need to move around.
  2. Stop the washing machine safely. If you can reach the controls without standing in water, press stop/pause and turn the machine off.
  3. If water is near electrics, only isolate power from a dry, safe spot.
    • If you can reach your consumer unit without stepping in water, and it is clearly dry, switch off the relevant circuit(s) (or the main switch if you can’t identify the circuit).
    • Do not touch the consumer unit or meter cupboard if you suspect water has got into/onto it, or if you see signs of overheating/arcing. Get a qualified electrician (or your electricity network/operator) to advise.
  4. Shut off the water feeding the washer.
    • Turn off the isolation valves (hot and cold) on the pipes behind/near the machine if you can reach them safely.
    • If you can’t, turn off your inside stop valve (stopcock/stop tap)—often under the kitchen sink, in an airing cupboard, or where the water pipe enters the home.
  5. Limit the spread. Use towels, a mop, or absorbent cloths to create a “dam” so water doesn’t reach sockets, boilers, or other rooms. If it’s still coming out, place a bowl/tray under the drip point.
  6. Protect nearby items quickly. Move anything that will be ruined by water (power strips, chargers, rugs, cardboard boxes, paperwork). Lift furniture legs onto towels/foil/blocks if you can.
  7. If you’re in a flat or there’s a unit below, alert them once it’s safe. After water is off and you’re out of immediate danger, notify your downstairs neighbour/building manager so they can check for water ingress.
  8. Document what you can. Take a few photos/video of: the leak source area, the water spread, and any damaged items (useful for landlord/insurer).
  9. Get the right help for your housing situation.
    • If you rent: contact your landlord/letting agent (use their emergency repairs route if available).
    • If you own: contact a plumber/appliance engineer.
  10. Before you turn anything back on: don’t restore water or power to the machine until the leak source is identified and areas around electrics are dry and safe.

What can wait

  • You don’t need to diagnose the exact failed part right now.
  • You don’t need to decide about replacing the machine today.
  • You don’t need to start a full “deep dry-out” immediately beyond stopping spread and making it safe.

Important reassurance

Most washer leaks look dramatic because they spread fast, but the situation usually improves quickly once the water is off and electrics are kept dry. Your job in the first minutes is safety and stopping further damage.

Scope note

This is first-steps-only guidance to stabilise the situation. If there’s water into ceilings below, under flooring, behind units, or near fixed wiring/meter equipment, you may need professional assessment.

Important note

This is general information, not professional or legal advice. If you can’t safely access shutoffs from a dry position, or you suspect water has affected your consumer unit/meter area, prioritise personal safety and get qualified help.
