On a Makita refrigerator, water where it should not be is most often a leaking water line, valve or filter connection rather than a water filter that is not seated, or the wrong cartridge. The supply side comes first, because a portable cabinet spends its life being unplugged, moved and plugged into something different. All three checks below are owner work, and not one of them needs a part.
What you are seeing
- A puddle at the front of the cabinet — Water at the front has usually run down from behind or out past the door seal.
- Water running down the inside walls of the cabinet — Condensation inside is an air-entry problem, so look at the door before the plumbing.
- Water under the crisper drawers with a dry floor — Water inside and nothing outside points at the drain path rather than the plumbing.
- NEAR MISS — water and the cabinet is also warm — Water with warmth is a cooling fault first; the cooling page ranks it correctly.
Causes, most likely first on this brand
- A leaking water line, valve or filter connection — Cabinets plumbed for ice and chilled water carry a line to a valve at the back and on to a filter head. Any of those joints can weep, and the water runs down the back and appears at the front as a puddle. It leads because a plumbed connection is the only part of this cabinet that carries mains pressure, and pressure finds every loose joint eventually. The cabinet is moved constantly, which is the single biggest difference between it and a kitchen appliance.
- An ice maker overfilling or its fill tube frosting over — If the fill valve passes more water than the mould takes, or the tube ices and diverts the flow, water runs into the freezer and freezes in a sheet on the floor of it. It ranks here because it is easy to confirm by looking, and because it damages nothing if caught early.
- A water filter that is not seated, or the wrong cartridge — A filter head seals on an O-ring. A cartridge that is a quarter turn short, fitted with the old seal still in place, or simply not the right one for the head, weeps steadily from the moment it goes in. It is last because the cabinet has no filter or none has been changed recently.
The order to check in
- Dry the back of the cabinet, then look again with a torch after an hour — A wet joint on a dry background is unmistakable, and it tells you which joint. First, because it is the likeliest to end the job.
- Open the freezer and look at the fill tube above the ice mould — Frost bridging the tube, or ice built under the mould, is the whole answer. Second, once that is clean.
- Turn the filter cartridge to check it is fully home — A quarter turn short is the commonest plumbed leak there is. Third, and by now the answer is usually in hand.
The steps, with tools and times
- Shut off the supply at the valve, then dry and inspect each joint — Isolate first and check afterwards, in that order.
Tools: cloth, torchAbout 20 min
- Switch the ice maker off and clear the ice from the mould area — Use warm water and patience rather than anything sharp.
Tools: warm waterAbout 30 min
- Turn the filter fully home, or refit it with the correct cartridge — Check the old seal came out with the old cartridge.
Tools: clothAbout 15 min
- STOP — isolate the water supply and note where the water collects — Where the water sits is the single most useful thing you can hand a technician.
The part that is not optional
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Shut the water supply off at its valve before touching any plumbed joint; a fitting that lets go under pressure empties into a kitchen faster than you can reach the stopcock.
When to call a technician
The line is the sealed system and the concealed plumbing. A drain cleared from inside, a tray reseated, a filter turned home and a gasket cleaned are all yours; a weeping valve behind a fitted cabinet is not. On this brand it is supported through the tool channel, so the parts that exist are the rugged ones.

This page is written for the appliance class, not for one Makita model line. Where a family- or model-specific page exists it is the better answer and it is linked below — go there first if your model is named.
