The short answer
A Hanover refrigerator leaking water is usually a blocked defrost drain rather than a burst line: the drain ices over, the defrost water has nowhere to go, and it runs out under the crisper or down the back. On this build the badge covers several unrelated factory platforms, so the cabinet in front of you matters more than the name on it, which is why the drain comes first below. Clean water at the front and water at the back mean different faults.
What you observe
- A slick of water on the floor at the back — A supply line, an inlet valve, or the drain pan overflowing, all reachable from behind.
- Ice building on the freezer floor under the vent — The drain is frozen rather than merely blocked, which is the same fault earlier in its life.
- Water running down the inside of the door — Condensation from a seal that no longer closes, not a plumbing fault at all.
- NEAR MISS: water inside and nothing cold — Cooling has failed and what you are seeing is the cabinet thawing. Read the cooling page first.
Causes, most likely first on this build
- Blocked or frozen defrost drain — Ranked first on this build: the drain on this platform is narrow and it silts up with the debris every cabinet makes, so it is the leak that turns up most often.
- Cabinet not level, so water runs forward instead of to the drain — Second: a cabinet that leans forward defeats a drain that is otherwise clear.
- Water supply line, fitting or inlet valve leaking — Third: the line is under pressure whenever the tap is open, so a weep here does not stay small.
- Door seal failing, so warm moist air condenses inside — Last: usually mistaken for a leak rather than being one, and it is easy to test.
Check in this order, and why
- Look for ice on the freezer floor under the rear vent — Ice there is the blocked drain caught early, and it confirms the diagnosis without any tools.
- Check the cabinet is level and tips back very slightly — A clear drain still fails on a cabinet that leans forward.
- Feel along the supply line and its fittings with a dry tissue — Only after the drain, because it is the less likely of the two and the harder to reach.
What an owner can safely check
- Flush the defrost drain from inside the freezer with warm water — Find the drain hole under the rear vent and flush it until it runs freely. Do not push anything rigid down it.
Tools: warm water, turkey baster or syringeAbout 20 min
- Set the feet so the cabinet stands firm and tips back very slightly — Water then runs to the drain rather than to the door, and the doors close themselves.

- Dry the floor, lay kitchen paper under the cabinet and check it after a day — Paper tells you where a slow leak is arriving, which no amount of looking will.

- STOP HERE if the next step needs the rear panel off or a fitting opened under pressure — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Water and electricity share the space under a refrigerator, so switch off at the breaker before you kneel in a wet area or move a wet cabinet, and unplug it before removing any panel. Shut off the water supply at its valve before touching any fitting. The cabinet is heavy, and a wet floor makes walking it out genuinely dangerous, so get help.
When to call a technician
Call once the drain runs free, the cabinet is level and the seal holds and water is still arriving, because the next step is the evaporator drain trough behind the rear panel. Call at once if the water is arriving fast, or if it is running near a socket or an extension lead, and shut off the supply and the breaker first. Parts are ordered against the model plate rather than the badge, and on a compact build the cost of a major part sits close enough to the cost of the machine that the quote decides the repair.

What this page does not cover
This page covers the Hanover refrigerator as a class rather than one family or model line. Drain trough routing, pan variants, supply fittings and the seal part numbers used on individual builds are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first; the nearest pages of this class are linked just above.
