What to do if…
your dishwasher is leaking water onto the kitchen floor mid-cycle

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Stop the dishwasher only if you can do it from a dry, safe position. Then cut power safely, shut off the dishwasher water supply if you can, and keep people away from wet electrics.

Do not do these things

  • Don’t stand in water and touch plugs, sockets, switches, extension leads, or the consumer unit.
  • Don’t keep the cycle running to finish.
  • Don’t pull the dishwasher out while it is powered, connected to water, or sitting in water.
  • Don’t put towels, mops, or your hands close to sockets, extension leads, or wet appliance cables.
  • Don’t restart the dishwasher to test it until it has dried and the cause has been dealt with.
  • Don’t use affected sockets or appliances if water may have reached them.

What to do now

  1. Get to a safer dry spot: Step away from the puddle. Keep children and pets out of the kitchen.
  2. Stop the cycle if it is safe: Use the dishwasher control only if it is dry and you can reach it without standing in water. If not, leave the controls alone.
  3. Cut power safely:
    • If the dishwasher has a wall switch, switched socket, or fused spur you can reach from a dry place, switch it off.
    • If you cannot reach that safely, use the consumer unit only if the route to it and the consumer unit area are dry and clearly not affected by water.
    • If there is any sign of water near the consumer unit, sockets, plugs, burning, crackling, buzzing, sparks, or heat, do not touch the electrics.
  4. Shut off the water if you can do it safely:
    • Look under the sink for the dishwasher isolation valve on the dishwasher supply pipe. It may be a small lever or slotted valve.
    • Close it only if the area is dry enough to reach safely and there are no under-sink electrics in the wet area.
    • If you cannot find it quickly, or it will not move, shut the mains stop tap only if you can reach it safely.
  5. Limit the spread of water: From a dry position, use towels or a mop to stop water spreading towards sockets, appliance bases, doorways, and under-cabinet gaps. Do not reach under the dishwasher.
  6. Take quick evidence from a safe position: Photograph the water spread, the dishwasher, and any valve or switch you used. Then stop handling the appliance.
  7. If you rent: Tell your landlord, letting agent, building manager, or emergency repair contact as soon as you can. Say: “Dishwasher leaking mid-cycle; water on kitchen floor; power and water isolated where safe.” Ask what they want you to do next.
  8. If water may have reached electrics: Keep the area out of use. Arrange a qualified electrician or appliance engineer before restoring power, using affected sockets, or using the dishwasher again.
  9. If there is immediate danger: Call 999 if there is fire, sparking, smoke, serious electrical danger, or someone is at immediate risk.

What can wait

  • You do not need to diagnose the exact part now.
  • You do not need to decide repair or replacement now.
  • You do not need to pull the dishwasher out now.
  • You do not need to clean behind cabinets until the power and water risk is controlled.
  • You do not need to argue fault or responsibility while water is still spreading.

Important reassurance

This is a fix-the-moment problem first. The useful order is simple: dry distance, power off if safe, water off if safe, stop the spread, then get the right help.

Scope note

These are first steps only to stabilise the situation and reduce harm. Drying, inspection, insurance, tenancy questions, and repair may need specialist help later.

Important note

This is general information, not legal, electrical, insurance, tenancy, or professional repair advice. If you are unsure about electrical safety, stay away from the wet area and get qualified help.
