Appliance Leak: What to Do First

Most appliance leaks start small and stay quiet. A washing machine hose develops a slow drip, a dishwasher connection works loose, or a refrigerator water line starts to seep behind the unit, and the water runs under the floor or behind a cabinet where nobody sees it. The first sign is often a damp patch, a warped floorboard, or a smell that was not there before. By then the water has been at work for some time, and the damage is already beyond the appliance itself.

This guide covers what to do first when an appliance leaks, for the three appliances that cause most of these losses: washing machines, dishwashers, and refrigerators. The steps are general, and they apply whether the leak is a slow seep or a sudden failure. The aim is to help you stop the water, protect what you can, and know when the job has gone beyond a mop and a towel.

Washing machine leaks

A washing machine leak usually comes from one of three places: the supply hoses, the drain hose, or the machine itself. Supply hoses are the most common cause, and they can fail suddenly after years of pressure, or slowly at a connection that has worked loose. If you find water around a washing machine, the first step is to shut off the water supply to the machine, using the valves behind it if you can reach them safely, or the main shut-off for the house if you cannot. Then turn the machine off, if you can do so without stepping into standing water.

Do not pull a washing machine out across a wet floor, and do not unplug it while standing in water. If the machine has flooded the laundry room, keep people out of the water and call for help. A leak that has been running for some time may have soaked the subfloor and the base of the walls around the laundry area, and that damage is easy to miss until the drying stage begins. Take photographs from a dry place before anything is moved, because the pattern of the water is useful evidence for the team that will inspect it.

Dishwasher and refrigerator leaks

A dishwasher leak often starts at the door seal or at the water connection underneath the unit, and the water runs under the kitchen floor where it is hidden by cabinets and plinths. The first sign is often a floor that feels uneven near the dishwasher, or a musty smell in the kitchen that will not go away. If you find water around a dishwasher, shut off its water supply if you can do so safely, and do not run the machine again until it has been looked at. The same applies to a refrigerator with a water line: the leak is usually behind the unit, where the line connects, and the water runs under the floor.

A refrigerator leak can also come from a blocked defrost drain, which sends water onto the floor inside the fridge and then out onto the kitchen floor. That kind of leak is usually small, but it can run for a long time unnoticed. In both cases, the response is the same: stop the water if you can do it safely, move what you can to dry ground, and do not touch any electrical item that is wet or sitting in water. A leak that has soaked a kitchen floor needs drying, not just mopping, because the water will have reached the subfloor.

Appliance Leak: What to Do First — Texas water damage guide

Shut the water off if safe, and move belongings

For any appliance leak, shutting off the water supply is the most useful first step, if you can do it safely. The valves for a washing machine are usually behind the machine, the dishwasher supply is usually under the sink, and the refrigerator line usually has a small valve nearby. If you cannot reach a valve without stepping into standing water, use the main shut-off for the house instead, or leave it and call for help. Do not spend long searching for a valve while water is spreading.

Once the water is stopped, move what you can to dry ground: rugs, cushions, papers, and anything on the floor near the leak. Lift furniture legs onto blocks if you have them, and move smaller items to a higher shelf or into a dry room. Do not move a large appliance that is standing in water, and do not unplug anything that is wet. Take photographs of the damage as you go, from a dry place, and note when you first noticed the leak and what you have already done.

When to call a professional

Call a professional when the leak has spread beyond a small area, when water has reached walls or flooring, when the floor is covered in standing water, or when the leak has been running for some time and the damage is unclear. A visit covers the inspection of the affected area, including the places water hides, such as under flooring and behind cabinets, and then moves to water removal, drying, cleaning, and repair. The appliance itself is a separate matter, and the restoration team covers the water damage it caused.

Before the visit, write down what you noticed and when, and keep the photographs you took. If you are in the Waco area, water damage restoration in Waco follows the same first steps as anywhere else in Texas. For the water damage an appliance leak caused, water damage restoration is the service that covers the job, and structural drying and dehumidification is the service that deals with the moisture the leak left inside the floor and walls.

After the leak: drying, cleaning, and repair

Once the appliance leak has been stopped and the water is off, the drying, cleaning, and repair stage begins, and it is worth knowing what it covers before it happens. The visit starts with an inspection of the affected area, including the kitchen or laundry room, the rooms the water reached, and the places water hides, such as under flooring and behind cabinets. The team notes which materials are wet, how far the water has travelled, and what kind of water it is, and they may use moisture detection equipment to check for damp inside walls and under floors, because a surface that looks dry can still be wet underneath. The water removal stage takes out the standing water, and the drying stage follows, using air movement and dehumidification, checked with moisture readings rather than by eye, because the drying is not finished until the readings show the structure has returned to its normal level.

The appliance itself is a separate matter from the water damage it caused, and whether its repair or replacement is covered is a matter for the operator to confirm. What the restoration team covers is the water damage: the wet flooring, the damp walls, the soaked subfloor, and the belongings the water reached. The cleaning stage deals with the surfaces the water touched, and the repair stage puts back what had to be removed, from drywall sections to flooring and finishes, and it comes after the drying, never before it, because repairing over damp materials stores up trouble for later. Before the visit, take photographs from a dry place, note when you first noticed the leak, and write down what you have already done. Keep a record of what was done on each visit, what the readings showed, and what was removed and why, because that record is useful for your own understanding and for any insurance conversation that follows.

Your Next Step

If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Water Damage Restoration page explains what that service covers, and the flood damage cleanup page explains how flood water is removed and the rooms are dried.

Do not step in standing water near electrical outlets or appliances while you wait, and if water is still coming in, turn off the shut-off valve for that fixture where you can reach it safely.

Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after bringing used appliances home.
