The short answer
This page covers the freestanding and undercounter installation of a BlueStar refrigerator — the listing is also written as the single word Bluestar. Fitted this way you can pull it out and look, which makes a leak far easier to trace than on a built-in column, and that reorders the fault list. A refrigerator holds food safely at 40 °F (4 °C) or below.
What you are seeing
- The problem began within days of the cabinet being moved or cleaned behind
- Water on the floor at the front of the cabinet
- A damp or darkening cabinet base or plinth beside the appliance
- Water pooling inside the fridge under the drawers
- Water appearing with the cabinet idle and the doors closed
- Water only after the ice maker has filled
- Body: When the water appears tells you which side it comes from: The problem began within days of the cabinet being moved or cleaned behind. Water on the floor at the front of the cabinet. A damp or darkening cabinet base or plinth beside the appliance. Water pooling inside the fridge under the drawers. Water appearing with the cabinet idle and the doors closed. Water only after the ice maker has filled.
Causes, most likely first
- The evaporation tray displaced when the cabinet was moved — Why: a freestanding cabinet is pulled out for cleaning far more often than a built-in one, and the tray above the compressor is a loose fit that is easily knocked.
- The cabinet standing out of level after being moved — Why: a cabinet returned tipped forward sends meltwater to the door instead of the drain, and the leak begins within days of the move.
- The water supply connection — Why: this joint is under mains pressure permanently, so a weep there wets the floor while the appliance is idle, and it is the leak that damages a kitchen rather than a cabinet.
- The water filter housing or its seal — Why: a filter changed without seating the O-ring correctly weeps continuously, and it is by far the most common leak immediately after routine maintenance.
- A blocked defrost drain — Why: meltwater that cannot leave collects inside the cabinet first, under the drawers, before it finds its way out to the floor.
- The ice-maker fill tube overshooting — Why: water that misses the mould freezes and then melts at the next defrost, which is the leak that appears only after a fill.

What to check, in order
- pull the cabinet clear and look at the tray above the compressor before dismantling anything inside, because on a freestanding cabinet that view is free.
- close the water shut-off valve serving the cabinet and see whether the leak stops, which separates the supply side from everything else immediately.
- if the leak followed a filter change, reseat or replace the filter, since that is the commonest single cause.
- if water is inside the cabinet under the drawers, the defrost drain is blocked.
- Body: Rule out the pressurised side first, because it is the one that keeps leaking: First, pull the cabinet clear and look at the tray above the compressor before dismantling anything inside, because on a freestanding cabinet that view is free. Second, close the water shut-off valve serving the cabinet and see whether the leak stops, which separates the supply side from everything else immediately. Third, if the leak followed a filter change, reseat or replace the filter, since that is the commonest single cause. Fourth, if water is inside the cabinet under the drawers, the defrost drain is blocked.
Checks you can do yourself
- Ease the cabinet out and check the evaporation tray above the compressor is seated squarely and not overflowing — Tools: a torch — Time estimate: a few minutes
- Close the water shut-off valve serving the cabinet and switch off at the breaker — Tools: torch — Time estimate: a few minutes
- Dry the floor and the cabinet base completely and lay paper towel along the front and at the sides — Tools: towels, paper towel — Time estimate: a few minutes
- Remove and refit the water filter, making sure it seats fully and its seal is not twisted — Tools: a replacement filter — Time estimate: a few minutes
- Remove the crisper drawers and check whether water is collecting beneath them inside the cabinet — Tools: torch — Time estimate: a few minutes
- Body: Isolate the water before you investigate: Ease the cabinet out and check the evaporation tray above the compressor is seated squarely and not overflowing (a torch; a few minutes). Close the water shut-off valve serving the cabinet and switch off at the breaker (torch; a few minutes). Dry the floor and the cabinet base completely and lay paper towel along the front and at the sides (towels, paper towel; a few minutes). Remove and refit the water filter, making sure it seats fully and its seal is not twisted (a replacement filter; a few minutes). Remove the crisper drawers and check whether water is collecting beneath them inside the cabinet (torch; a few minutes).
Safety first
Safety
A refrigerator holds food safely at 40 °F (4 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water inside cabinetry reaches the appliance supply, so isolate at the breaker before working and close the water valve first. Clear a drain only with a soft flexible tube, never with wire. unplug-before-service fridge-40f
When to stop and call a technician
These need a technician: The tray is cracked, or it overflows with the drain confirmed clear. Water continues with the shut-off valve closed, which means it is not the supply. The floor or the cabinetry has darkened, swollen or lifted. Water returns after the drain has been cleared and the filter reseated.

What this page does not cover
This page is generalized across every refrigerator sold under the BlueStar name: it separates neither the freestanding cabinets from the undercounter ones and the stainless fronts from the panel-ready ones, and it names no individual model. Where a family- or model-specific page exists it is linked here and it outranks this one for that machine; at present no page beneath this one narrows to a single family, so treat the ranking above as the brand-level pattern rather than a reading of your serial plate. The same appliances are listed as the single word Bluestar; those pages cover the built-in column installation and the deeper diagnostic tier, and they are linked here. For the other faults that turn up on this machine, start from Common BLUE STAR Refrigerator Problems.
