Why does appliance water damage often go unnoticed for days?
Appliance leaks often run slowly or out of sight, under the appliance, behind the cabinet or under the floor covering. The water can be absorbed by the cabinet and the subfloor before anyone sees a puddle. Damage can build up for days before a smell, a stain or a soft floor shows it.
A slow drip from a supply valve or a hose connection can soak a cabinet base over a long period. The board swells and softens, and the damp spreads under the floor covering. By the time the floor looks wrong, the wood underneath may be wet for a long way.
The crew reads the cabinet bases and the subfloor on the first visit, even when the floor looks dry, because the readings show what the water has reached. The homeowner is given the readings and the reasons for opening any cabinet.
What should you check on your own appliance after a leak?
Check the supply hoses and the valve for splits, bulges and drips, and check the drain hose for cracks. Look under the appliance and along the cabinet base for damp. Do not reconnect a hose that has failed. Ask a qualified person to replace it.
A rubber hose that has been in use for many years can crack or bulge without warning. A braided steel hose is less likely to split but can still leak at the fittings. Replace any hose that shows damage, rather than wrapping it with tape.
Keep the area around the appliance clear, so a leak is seen sooner. A small water sensor on the floor behind the appliance can give an early warning, though it does not replace the check.
Does the appliance have to be replaced after a leak?
Not always. A leak from a hose or a fitting often means the part is replaced rather than the appliance. A leak from the inside of the appliance, such as the tub, the pump or the controls, may mean a bigger repair. A qualified person decides, and the crew does not guess.
Water that has reached the motor, the controls or the wiring of an appliance needs inspection before it is used again. A qualified technician checks the unit and tells the homeowner whether it can be repaired or must be replaced.
Keep the receipts and the inspection note with the drying record. Those papers are useful for an insurer and for any warranty claim the homeowner may have.
What happens to a cabinet base after it has been wet?
A cabinet base that has been wet is read for moisture and swelling. Solid wood and plywood can often be dried in place if they have not swelled or softened. Particleboard that has swelled or lost its strength is replaced, and the crew explains the difference before it removes anything.
The toe kick and the bottom panel are the most common places for water to collect and stay. The crew removes the kick plate where needed to reach the wet area and to check the floor beneath the cabinet.
A cabinet that dries and then swells or warps may need to be replaced, even if it looked fine on the first day. Ask for the readings on each return visit to see whether the cabinet is coming back to a stable level.
What should the homeowner do while the area is drying?
Keep the appliance off and the supply shut off until it has been checked. Keep the cabinet doors open when the crew asks, and keep stored items away from the wet area. Photograph the damage before anything is moved, and write down when the leak was first noticed.
Dry cloths and towels can be used to soak up standing water, but they should be removed from the floor once they are wet. Do not run the appliance again to test it, because a fresh leak can start the cycle again.
Call the line if a new smell, stain or soft spot appears after the crew has left. A new reading that rises on a return visit means the source may still be active, and the crew will check the valve and the supply again.
