The short answer
The order that matters here is water running where you cannot see it first, a blocked defrost drain next and a unit that is not sitting square last. A built-in machine changes the ranking because the installation is part of the appliance: ventilation, clearances and the way the door sits in its opening are all things a free-standing machine never has to contend with. That ranking is the value of this page: the cheap causes are the common ones on Northland refrigerators, and the costly one is what people reach for first.
What you observe
- A wet patch that comes back after wiping — A continuous source rather than a one-off spill; it is worth finding where it starts.
- Ice under the freezer floor panel — The same blocked drain, one step earlier — the water freezes before it can back up into the fridge.
- Damp under the unit but dry inside — Either the drain pan or the supply connection — both live underneath or behind.
- NEAR MISS — water only in the ice bin, fused into a lump — That is a temperature or ice-production problem rather than a leak; the ice page covers it.
Causes, most likely first on Northland
- Water running where you cannot see it — On a built-in unit a leak runs along joinery and under flooring before it appears, often at the front of the plinth or in the cupboard next door. The visible water is rarely above its source. Placed there because it is first here because the damage from a hidden leak outruns the fault that caused it.
- A blocked defrost drain — Every frost-free unit melts frost off its evaporator on a schedule and sends the water down a small drain to a pan underneath. Kept just below the point above rather than dropped, because it leads because water under the crisper drawers has one likely cause and this is it.
- The supply line and its connections — Supply-side leaks do not care whether the unit is running, which is how they are told apart from everything else here. Third, once the two above are clean: it is second because it is the only leak here that continues while the appliance is switched off.
- A unit that is not sitting square — Levelling is behind several of the causes above rather than being a leak in itself. Bottom of the list, deliberately: a unit that is out of true undermines the whole diagnosis, which is why it is worth settling early.
Check in this order, and why
- First: Check the neighbouring cupboards and the plinth — Water surfaces at the nearest gap, which is rarely above the joint that is leaking. It is first because it is the cheapest of the three to settle.
- Second: Look for water under the crisper drawers — Lift the drawers out and look at the floor of the cabinet, then at the drain hole at the back.
- Third: Pull the unit out and look at every joint — Dry each connection, then come back in an hour with a torch and a piece of paper towel.
What an owner can safely check
- Clear the defrost drain from inside — Empty and remove the drawers, find the drain opening at the back of the cabinet floor, and flush it with warm water.

- Check the supply line and filter head — Dry every joint, put paper towel under each, and check them again after an hour.

- STOP HERE if the next step needs a meter on live terminals — That is the line between an owner check and a service call, and it is not worth crossing.
Isolate before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel, and treat every capacitor as still charged: a capacitor can hold a charge after the power is off. Do not attempt anything on the sealed system: refrigerant work is licensed work. Never chip ice off an evaporator with anything metal, because piercing a coil ends the appliance.
When to call a technician
The owner side here is the drain, the seals, the levelling and a look underneath. Past that the panels come off.

What this page does not cover
This is generalized information for Northland refrigerators as a class, not for one family or one model. No family- or model-specific page for this brand and appliance is published here yet, so nothing narrower is linked; when one is, it becomes the more specific answer and this page will point to it. No part numbers, no wiring detail, no dismantling sequence: those vary by family and are only useful beside the family they describe.
