Homeowners’ insurance has denied claims for dishwasher water damage if they see evidence of a slow leak that wasn’t repaired. So it’s best to prevent a dishwasher from leaking before it causes problems.
Causes Of Dishwasher Water Damage
Slow leaks are the biggest culprit because they go unnoticed for so long. The water rots wood, damages tile and other flooring materials, and creates the perfect environment for mold growth.
Supply Line Leaks
Leaky Water Inlet Valve
This valve provides fresh water from your plumbing to your dishwasher. Leakage occurs most often from the valve or the water hose connection.
Water drips from the bottom of the dishwasher and isn’t usually visible. Check for this issue at least twice a year by grabbing a flashlight, removing the kick plate, and looking for signs of water or water damage.
A Deteriorated Door Gasket
The gasket around the door of your dishwasher will deteriorate. You can help extend its life by wiping it down often and removing soap scum once a week.
Leakage from a deteriorated dishwasher gasket is easier to spot since the leak will happen around the door. Replace the gasket if you notice cracks or if it becomes brittle.
Drain Hose Leak
The drain hose is another component of your dishwasher that degrades. Remove the kick plate and inspect the hose. Replace as needed.
A Defective Float Switch
The float switch controls the dishwasher’s internal water level. At a certain level, the float switches off the water supply from the inlet valve.
When it’s not working, excess water enters the machine, and the dishwasher to leak. Replacement of the float switch by a professional is the only way to fix this problem.
Overflow Water Damage
Another cause of water damage is overflow, when water actually pours out of the machine.
- Slow leaks may burst in time from the water pressure.
- Food debris caught in the dishwasher gasket may prevent the door from closing fully.
- Defective solenoids in your water inlet valve may block water flow when the machine is closed. The opposite is also true; the valve may allow too much water in, which will cause your machine to overflow.
- Using too much detergent, or a detergent that isn’t intended for dishwashers, causes oversudsing. Always use the manufacturer’s recommended brands or a high-quality dishwashing detergent.
