The short answer
Almost all refrigerator water is the cabinet's own condensate that has lost its way to the drain, not water from a supply line. Where the water appears tells you which: water inside the box is a drain fault, water at the front is usually stance or seal, and water at the back or under the middle is a supply or pan fault. On a Royal Sovereign refrigerator the cause that ranks first is door gasket letting in humid air.
What you observe
- A sheet of ice or standing water under the crisper drawers — The classic signature of a blocked defrost drain: water backs up inside the box instead of leaving it.
- Water appearing at the front of the cabinet, on the floor — Either the interior water has run forward because the cabinet is tipped that way, or the door is not sealing and warm air is condensing on the frame.
- NEAR MISS — water only after someone uses the dispenser — That is a dispenser or fill-tube fault and belongs on the ice and water page, not here.
Causes, most likely first on a Royal Sovereign refrigerator
- Door gasket letting in humid air — Warm air entering the box condenses on the cold surfaces and runs. Ranked first on this refrigerator, because a seal fault produces water without anything actually being broken.
- Defrost drain blocked or frozen — Debris silts the drain hole and the tube below it freezes solid.
- Cabinet standing out of level — A cabinet tipped forward sends interior water and condensate to the front instead of to the drain, and holds the doors slightly open into the bargain.
- Condensation in a humid or warm space — In a garage, a workshop or a humid climate the cabinet sweats on its outside surfaces and around the door frame, and that water is not a fault at all.
Check in this order, and why
- Run a sheet of paper round the gasket with the door closed — Any point where it pulls out freely is letting humid air in.
- Clear the drawers and look at the floor of the fresh-food compartment — Standing water or ice there settles the question immediately and points at the drain, not the plumbing.
- Put a level on the top of the cabinet, front to back and side to side — It costs a minute and it changes how you read every other clue.
What an owner can safely check
- Test the gasket all the way round with a sheet of paper and clean the sealing face — Wipe the gasket and the frame it lands on.
Tools: clothAbout 10 min
- Empty the bottom of the cabinet and flush the drain hole at the back wall with warm water — Use warm water and a soft flexible line, never a wire or anything sharp.
Tools: turkey baster or soft tubing, warm water, clothAbout 25 min
- Level the cabinet, with the front very slightly high so the doors self-close — Adjust the front feet or rollers.
Tools: spirit level, spannerAbout 15 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins, whatever the ranking above says.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any interior panel — a capacitor can hold a charge after the power is off. Shut the water off at the supply valve before touching any plumbed joint. Water on a floor beside a powered appliance is a slip and shock hazard: dry it before you work, not after. Never clear a drain with a wire or anything sharp, and never cut or open a sealed-system line.
When to call a technician
Call when the drain, the stance and the gasket are all clean and water is still appearing, or the moment you find water arriving from a plumbed joint you cannot isolate. Call immediately if water is reaching a socket, a cord or anything electrical.

What this page does not cover
This page is written for the Royal Sovereign refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked above, it is the more specific answer, and it is the one to read first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, which differ between families under the same nameplate.
