Why is there water under my refrigerator?

Why we start there

Clear water at the front is plumbing; cloudy water with freezer ice is the drain.

What happens next

Both are small repairs, and neither one stops until somebody opens the unit up. In a dry valley house the plumbing version regularly goes unnoticed for weeks, because a slow drip evaporates off tile nearly as fast as it lands. If you have found a white or gray outline under the unit and no standing water at all, that is still a leak. It has simply been drying as quickly as it arrives, and in the meantime it has been running down the back of the cabinet and into the subfloor, where nothing evaporates. This is the fault we would far rather hear about today than next week. The repair itself is a fitting, a valve, or a drain that needed clearing. The floor is not, and on the engineered wood and stone that goes into these kitchens the damage overtakes the cost of the repair within a few days of getting started.

On the visit the drain gets traced from the evaporator down to the tray and flushed properly rather than poked at, along with the drain heater on the models that carry one. Then every fitting from the shutoff through to the inlet valve, including a saddle valve if the installation predates a proper stop, and the valve body itself for weeping. The door seal comes last, because condensation forming at a gasket leak looks exactly like a drain problem by the time it has reached the floor. If the unit stands on stone and the water is finding a grout line rather than pooling, mention it when you call. It changes how quickly we need to be there.

If that matches what yours is doing, say so when you call — it decides which parts come on the van.
