Start here
A leaking PFQZ unit is telling you where its meltwater is going, not that it is broken. The room does as much as the machine here: humidity and door traffic set how much water there is to shift, so the ranking below departs from the brand-generic order.
The observables
- Contents at the base sitting in water — Labels soften and packaging swells while everything higher up is dry.
- A wet gasket all along one edge — The seal line itself is beaded, which points at where the warm air is getting in.
- The leak tracks the weather — Worse on humid days, absent in a dry cold room, with nothing about the unit changed.
- NEAR MISS - water only once, right after a move — A unit laid down or carried warm sheds what it was holding. One puddle after a move is not a fault; a second one is.
Causes, most likely first on this line
- A humid room and frequent opening — First here, and by a wide margin: this is not a fault, but it is the reason a unit that never leaked in one house leaks in another. The evidence is a leak that tracks the weather and the household routine.
- Warm air getting past the door or lid seal — Second on this line: a compact cabinet has one gasket doing all the sealing, and warm room air that reaches a cold surface gives up its moisture there. A gasket that has taken a set, or that is held open a fraction by a shelf or a full basket, condenses water continuously without ever letting the cabinet warm enough to be noticed.
- A blocked condensate drain path — Third: a restricted drain does not stop the water, it delays it. The melt pools where it cannot be seen, then arrives all at once as a puddle that looks far bigger than the fault behind it.
- A split drain hose or a failed seam — Last on the list, and the only one here that is not owner work: a failed seam leaks the same amount whatever you do to the drain, which is what separates it from everything above. It is also the fault that wets insulation, so it gets worse rather than staying level.
The order to work in
- Account for the room and the routine — Ask how humid the room is and how often the door is opened, and compare with what the unit did before it was moved. The answer often removes the need for any repair.
- Test the seal along its whole length — Run a hand round the closed door for a cool draught, then look at the gasket for a flattened section or a fold that has taken a set.
- Clear and test the compartment drain — Empty the compartment, find the outlet in the floor, and pour a little warm water at it. If it stands rather than draining, that is the fault and nothing further needs checking.
Before any panel comes off
Safety
Isolate the unit at the plug or the breaker before any panel comes off - a capacitor can hold a charge after the power is off. Mop the floor first: standing water underneath a cabinet you are about to tip or move is how this job hurts people.
When this stops being owner work
Two conditions make it a call rather than a check: water that returns with the compartment empty and the drain proven clear, and any water at the electrical end. A third is a leak that has already soaked the base, because wet insulation does not dry out in place.
