Water Damage From an Appliance: What Leaks Slowly and Costs the Most

Ge dishwasher leaking, and the leaks that matter more

A puddle is annoying. It is also visible, which makes it the cheap kind.

The expensive leaks are the ones nobody sees: a connection weeping behind a dishwasher into the cabinet base, an icemaker line dripping behind a refrigerator that has not been moved in six years, a washer hose seeping into a wall. In a warm humid house those find flooring, subfloor and drywall long before they find anybody's attention.

Where they start

Hose connections and their washers. Rubber washers harden with age and begin to seep years before anything bursts. This is the commonest slow leak in any house and the cheapest to prevent.

The icemaker line. Small-diameter tubing behind an appliance that never moves, often joined with a saddle valve that was fitted decades ago. Both the valve and the joint are candidates.

A dishwasher door gasket, along its lower edge, where debris collects.

A washer's door boot seal, especially on a front loader, and especially where the fold has been holding grit.

The drain path, which produces water only during one part of the cycle — which is the clue.

The clue that matters

Note which part of the cycle it leaks in. Fill, wash, drain or spin: each points somewhere different, and this is the one piece of information we cannot gather ourselves on arrival.

Water travels along the base frame before it emerges at the front, so where you see it is rarely where it starts. Tracing it is most of the repair, and knowing the moment narrows it dramatically.

When the appliance stops itself

GE's dishwashers with leak detection cancel the cycle rather than finishing it when they sense water in the base tray.

That is the appliance making a better decision than most people would, and it should be respected rather than reset past. The message means water reached somewhere it should not, and clearing the message does not put it back. Look underneath and behind first.

The same principle applies to any appliance that has stopped itself: it stopped for a reason, and the reason has not gone away because the display is clear.

The Florida part

Two things make this local.

Slabs. A slow leak under a dishwasher in a slab house goes into flooring and stays there. There is no crawlspace to drip into and no basement to notice it in.

Humidity. Everything dries more slowly, so a leak that would evaporate in a dry climate stays wet, and what stays wet grows. The mold conversation and the water damage conversation are the same conversation here.

Worth doing before anything is wrong

Pull the washer out once a year and look at the hose connections. Check behind the refrigerator when the condenser gets cleaned — the same visit, no extra effort. Replace rubber washing machine hoses with braided stainless ones; they cost very little and they are the single highest-value preventive item in a laundry room after the vent.

None of that is a repair. All of it is cheaper than a floor.
