The short answer
On the Arieta ARWS refrigerator line, an ice maker that has stopped is worth working through in a set order: a freezer that is not cold enough to harvest first, then a clogged water filter or a failing inlet valve, and only after those does the sealed system enter the picture. That order is written for a single-model line and sequenced for how these models are put together, which is where it departs from the brand-generic article.
What you observe
- The freezer is cold but the ice cream is soft — A compartment running warm will hold food and still refuse to harvest ice.
- Cubes are small, hollow or misshapen — Correct cycling on insufficient water. The mechanism is working; the water is not arriving.
- NEAR MISS — nothing in the cabinet is properly cold — Then this is a cooling fault and the ice maker is a symptom, not the problem.
Causes, most likely first on the ARWS line
- The freezer is not cold enough to harvest — First on this list: the ice maker will not eject a tray until its own thermostat sees the cubes frozen hard, so a freezer sitting a few degrees warm — a door left ajar, a packed compartment, a failing seal — stops production without stopping the machine.
- A clogged water filter or a failing inlet valve — A tired filter or a weak inlet valve starves the mould, which shows up as small or hollow cubes rather than as no ice at all.
- The shut-off arm, the ice bin or a control setting — The shut-off arm or sensor is blocked or switched off often enough that it is worth ten seconds before anything else.
- The water supply is off, restricted or frozen at the inlet — The supply is still worth re-checking at the end, because a slow line can mimic every internal fault on this list.
- The ice maker module, its heater or the wiring to it — Last here, and the only cause on this list that is not owner work — a module that will not cycle, a harvest heater that has failed or a broken connection to the freezer harness is replacement work behind a panel, with the power off and the part matched to the cabinet.
Check in this order, and why
- Measure the freezer temperature rather than trusting the display — A freezer holds food safely at 0 °F (−18 °C) or below, and an ice maker wants to be there too. Done first because it separates the likeliest causes before any tool is needed.
- Check when the filter was last changed and run the dispenser into a jug — Second: it confirms or dismisses what the first check suggested.
- Look at the shut-off arm or sensor window and the seating of the bin — Third, once the two checks above are clean.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Shut the water off at the wall valve before touching any fitting, and have a towel ready — the line stays charged after the valve closes. Do not prise ice out of the mould with a screwdriver; the heater element sits directly underneath it.

When to call a technician
Call when water reaches the mould, the freezer is genuinely cold and nothing ever ejects, because that is the module and it is replaced behind a panel. Call sooner if you find water anywhere it should not be while you are looking.
