What this usually is on these models
On WTW units the ice complaint means different things depending on whether the unit makes ice automatically. Where a unit in this line makes ice automatically, water arriving is the first thing to prove and the cheapest, so the first step below establishes which question is being asked. The order below puts no water reaching the ice maker, where one is fitted first and the ice maker mechanism itself last, and that order is the point of the page.
What you observe
- Production tailed off over weeks — Fewer cubes, then none, alongside a compartment that is not quite as cold as it was.
- Ice overnight and none during the day — A pattern that follows use and room temperature rather than the machine.
- A mechanism that cycles and delivers nothing — Where a unit has an automatic ice maker, it goes through the motions with nothing in the mould.
- NEAR MISS - everything freezes solid — Over-freezing is the opposite complaint and runs the diagnosis the other way, starting at the setting and the control.
Ranked causes for these models
- No water reaching the ice maker, where one is fitted — Ranked first on this line: where a unit in this line makes ice automatically, it can only do that with water arriving. An empty reservoir, a closed or kinked supply, or a line that has frozen at its coldest point all stop production with the unit otherwise healthy.
- A cycle that is slower than expected — Next, and close behind: the tell is a compartment that measures properly cold with no ice yet in it.
- The ice maker held off by its arm or sensor — Then: the fault looks like a dead ice maker and is undone by hand in seconds, which is why it belongs above anything mechanical.
- The ice maker mechanism itself — Last, and the reason the order matters: it is identified by watching a full cycle: a mechanism that never moves, or that moves and never fills, has named itself.
What to check first, second, third
- Establish that water is arriving at all — Watch one fill. Water arriving and no ice forming is a temperature problem; no water arriving is a supply problem.
- Judge production over a day, not an hour — Empty the bin, note the time, and look again after a full undisturbed day. That is the only measurement of production that means anything.
- Check what is telling it the bin is full — Note whether production stopped abruptly or declined. Abrupt stops point at a switch or a sensor; decline points at temperature.

Safety
Switch off at the breaker or pull the plug before you reach into the compartment mechanism, since a capacitor can hold a charge after the power is off. Do not run a lead across a wet floor while defrosting, and keep meltwater away from the machinery end.

When to call a technician
Call if production tailed off over weeks together with a compartment that is no longer as cold as it was, because that combination points at capacity rather than at ice. A sudden stop with normal cooling is usually still an owner fix.
