The repair against the replacement
| What it takes | Range |
|---|---|
| Ice maker, water valve or supply line | $270–$830 |
| Buying another one instead | $12,710–$21,440 |
That last row buys a like-for-like built-in on its own, with nothing allowed for fitting it or for the joinery around it. Every figure above it is being weighed against that, which is why a structurally sound cabinet is usually worth putting right even when the quote makes you wince.
Water under a built-in rarely arrives from where the owner assumes. The cabinet gets blamed, when in practice it comes from one of three narrow and well-understood places, only one of them expensive. Working out which, before the floor comes up, is the job.
Where the water actually comes from
The fill side is first. The control watches how long its ice-maker water valve stays energised and complains once that runs past fifteen seconds repeatedly; the service documentation then sends a technician to a jammed cube, the levelness of the ice maker, the fill cup position, the supply pressure and finally the valve. Any of those also wets the freezer floor.
The drain path is second. Meltwater from each defrost should run off the coil and away; when the heater keeping that route open has failed, it goes over the edge instead and finds the base of the cabinet.
Third, and least visible, is the supply line — quarter-inch copper, braided stainless or plastic tubing to a shut-off valve the installation instructions say must be easy to reach, with self-piercing valves ruled out outright. In an old kitchen it is frequently none of those things.
What the water does after it arrives
A cabinet wet underneath for a week has a plumbing repair in it. One wet for a season may have a soft sub-floor, and these cabinets are levelled to the floor, not to the joinery beside them — if the floor will not hold a level, the machine cannot be set back properly however good it is. The other lasting harm is inside the doors and the liner, where foam that has taken water does not dry out in service and no part number fixes it.
Shut the supply off if you can reach the valve, and mop. Everything past that is a plumbed joint or a live connection. What helps most is noting whether the water appears on a cycle or steadily, and whether the back wall has been frosting.
What we usually find
-
A puddle appearing at the plinth every few days with nothing obvious above it
The fill side of the ice maker. A jammed cube, a fill cup knocked out of line or a valve holding open too long all put water where it does not belong.
Ice maker, water valve or supply line $270–$830
-
Water at the base of a cabinet that has also been frosting across the back
The defrost side rather than the supply side. Meltwater goes over the edge of the trough instead of down the drain, usually because the heater keeping that path clear has quit.
Defrost heater, thermostat or sensor $280–$640
-
A slow stain spreading under the joinery beside the machine rather than in front of it
The supply line and its fitting behind the cabinet, often a soft copper tail on a valve nobody has turned in twenty years. Plumbing rather than appliance work.
Quoted after the diagnosis
-
A floor that has lifted and a kickplate that will not sit flat any more
Water that stopped being an appliance fault some time ago. The sub-floor now decides whether the machine can be levelled back into its opening.
Quoted after the diagnosis
Which of these it is gets settled at the visit, before a part is ordered — Sub-Zero Repair Pro Los Angeles, (310) 844-1973.
Which way it points
Repair it if
- The water is coming from the fill side or the drain and the floor below is still sound
- The liner, the door foam and the insulation are dry and have stayed dry throughout
- The case can still be levelled to the floor once it goes back into the opening
Replace it if
- Water has reached the liner or soaked into the foam inside the doors
- The floor under the opening has to be lifted and rebuilt whatever happens next
- The supply side has failed twice and the cabinet has sat wet in between
If your machine sits between the two columns, that is what the diagnosis is for: Sub-Zero Repair Pro Los Angeles measures it first and gives you the figure before any of it is committed to — (310) 844-1973.
Follow-ups
- Should I shut the water off myself before anyone comes out?
- If the shut-off valve for the refrigerator is accessible and you are sure which one it is, yes, and that is the one thing worth doing first. Leave every fitting, joint and electrical connection alone. Sub-Zero Repair Pro Los Angeles traces the rest at the visit, on (310) 844-1973.
