Start by unplugging the fridge if the cord and outlet are dry, then shut off its water supply and pull the unit out with a helper. Soak up standing water, photograph the damage, and check the floor, the cabinet toe kicks and the wall behind it. Wet materials need to be dried within 24 to 48 hours to head off mold.
Most fridge leaks come from the ice maker line, the water filter line or a clogged drain. The water is usually clean at first, but it spreads under flooring where you cannot see it. The sections below cover each step in order.
Where refrigerator leaks usually come from
- The ice maker supply line, a thin tube behind the unit that can crack, loosen or get kinked when the fridge is pushed back.
- The water filter housing and its fittings, which can drip when a filter is changed or seated badly.
- The defrost drain, which can clog with ice and send meltwater over the edge of the drain pan.
- The drain pan itself, which can crack or overflow on older units.
- The saddle valve or shut-off at the wall, where the supply line connects.
Slow leaks are the tricky ones. A drip that lands on a vinyl floor can run to a seam and slide under it, then sit against the subfloor for weeks. By the time you notice a soft spot or a musty smell, the damage is already well past the visible edge.
Look for warped boards near the fridge, a floor that feels spongy, a baseboard that has swelled, or a stain on the cabinet side facing the unit. Any of those means moisture has traveled farther than the spot you can see.
Pulling the fridge out safely
Check the cord and the floor first
Do not touch the fridge or its cord if you are standing in water or if the outlet looks wet. Cut power at the panel only if you can reach it while dry. If you smell gas from a nearby range, or water has reached an outlet or panel, stay out and call the utility or 911 before you call a restoration company.
- Unplug the fridge only if the cord, plug and outlet are completely dry.
- Close the water supply valve to the ice maker or filter line, usually behind or beside the unit.
- Get a second person. Fridges are heavy and floors may be slick.
- Slide the unit out slowly, straight forward, and watch the water line so it does not kink or tear.
- Wipe up standing water, photograph the floor, the wall and the unit, and leave the area open to air.
Do not drag a heavy fridge across a wet or soft floor. If the floor flexes under your feet, stop and have a crew lift the unit. Ripping a damaged floor further can turn a small repair into a larger one.

What the water soaks and how far it travels
Water goes down, then sideways. It enters seams in the flooring, soaks into the subfloor, and wicks into the bottom of cabinets and drywall. The toe kick, the thin panel at the base of your cabinets, is often the first wood part to swell.
A moisture meter shows what the eye cannot. Crews also use thermal cameras to find cool, wet areas behind surfaces without opening everything. That mapping tells you which areas can dry in place and which have to come out.
Wet insulation in a nearby wall and drywall that stayed wet are often removed rather than dried. It depends on how long the water sat and what the materials are. Water mitigation is the stage that stops this spread, and it is most useful in the first few days.
Water category: clean at first, worse if it sits
The published ANSI/IICRC S500 standard sorts water by contamination. Category 1 is clean water from a supply source, which includes an ice maker or filter line. Category 2 has significant contamination, such as washing machine discharge.
Clean supply water does not stay clean. Once it soaks into flooring, carpet pad or wood and sits for a day or more, it can pick up contaminants and be treated as Category 2. That changes what can be saved, because porous materials in contact with Category 2 water are more likely to be removed.
Mold needs moisture, and the EPA says to dry water-damaged areas and items within 24 to 48 hours. Fix the water source first, then dry. If you see mold over about 10 square feet, or the water has been sitting for days, call a professional and see mold remediation for how containment and removal follow ANSI/IICRC S520.
Dry it or replace it: flooring by type
| Flooring | What the leak does | Often dried in place? | Often replaced? |
|---|---|---|---|
| Laminate | Swells at edges and seams, core board does not recover well | Rarely if boards have swelled | Usually the affected planks |
| Vinyl plank or sheet | Water gets under seams and sits against the subfloor | Sometimes, if lifted and the subfloor is dried | If it bubbles, curls or traps moisture |
| Solid hardwood | Cups or crowns as it takes in water | Sometimes if caught early | If it stays cupped, stained or soft |
| Engineered wood | Layers can separate | Occasionally in small areas | Often the affected boards |
| Tile | Surface unharmed, but grout and subfloor below may be wet | Often | Rarely, unless the subfloor is damaged |
| Carpet and pad | Pad absorbs and holds water | Carpet sometimes | Pad often |
These are general patterns, not promises. Each floor depends on how long it stayed wet, what is underneath, and whether the water was still clean. A crew with moisture readings can tell you which boards or sections can stay.
Subfloor matters most. If plywood or OSB under the fridge has swelled or delaminated, the floor above has to come up. After drying, water damage repair rebuilds what was removed, including flooring, toe kicks and trim.
When to call a crew
Call if you see standing water, a soft or warped floor, damp cabinets, or any smell that suggests water has been sitting. If the unit has been leaking for an unknown time, assume the damage is wider than it looks. An emergency water removal crew can pump and extract water and begin drying, and water damage cleanup handles wet debris and sanitizing once the source is stopped.
Scope and price explained before work starts is what you should ask for. Ask whether the crew works to ANSI/IICRC S500 and whether the company is registered with Washington L&I.

Mukilteo local note: who to call about power and gas
According to the City of Mukilteo's utilities page, electric service in the city comes from Snohomish County PUD and natural gas comes from Puget Sound Energy. Both matter in a kitchen, since a fridge shares outlets and sometimes a wall with a range.
So if water reached an outlet, the panel or the cord, or you smell gas, call the right utility or 911 before you call a restoration company. Keep the PUD and Puget Sound Energy numbers where you can find them, and do not plug the fridge back in until the outlet is confirmed dry.
Frequently asked questions
Look for warped or lifted flooring near the fridge, a soft spot, a musty smell, or damp cabinet sides. A moisture meter can confirm what you cannot see.
Only if the cord, plug and outlet are completely dry and you are not standing in water. If not, cut power at the panel only if you can reach it dry, or call the utility or 911.
It depends on the floor type, how long it stayed wet and what is under it. Tile often can be dried, while laminate often needs replacement. A crew with moisture readings can tell you.
The EPA says to dry water-damaged areas and items within 24 to 48 hours. Mold needs moisture, so fixing the source and drying fast are the key steps.
Sudden and accidental leaks are often covered, while slow leaks over time often are not. Check your policy or ask your insurer before repairs, and photograph the damage first.
The City of Mukilteo lists Snohomish County PUD for electric and Puget Sound Energy for gas. Call the right utility or 911 before you call a restoration company, and stay out of the area until it is safe.
