The short answer
An ice-making fault on a WTW refrigerator usually comes down to the plate losing contact with what it is meant to freeze, whether through frost, packing or a tray that never touches it. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
What you actually observe
- It freezes on mains power but not from the vehicle socket — A supply difference, not an appliance difference.
- Ice forms only on one side of the compartment — Contact and airflow: what touches the plate freezes, what does not, will not.
- Drinks are cold but nothing in the compartment freezes — The classic split: refrigeration is working, freezing duty is not being reached.
- The whole box is warm and nothing is cold at all — NEAR MISS: that is a cooling failure, and the not-cooling page is the better read of it.
- Body: No two WTW listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
What causes it on the WTW platform, in likelihood order
- 1. The set point and the operating mode — Before anything is suspected, the set point has to be low enough to freeze and the mode has to allow the compressor to reach it. Most reports of no ice end here. It ranks high on WTW because the two listings are close enough in size that usage, not capacity, decides the outcome.
- 2. Where things sit inside the box — Freezing happens against the plate. A tray held off it by a basket, a divider in the wrong slot, or a layer of packaging between the two, and the contents sit in cold air instead of on a cold surface. Second here because it costs nothing to ask, while the cause above it explains more of what owners report on WTW.
- 3. Supply voltage and the battery-protection cutoff — The tell is that chilling still works. A supply that sags under load makes the controller stop the compressor early and often, which is enough to hold a chill but never enough to freeze.
- 4. Warm air leaking in past the seal — A seal that leaks costs the last part of the pull-down, which is exactly the part that makes ice.
The order to work in on this platform
- 1. Read the set point and the mode on the panel — Costs nothing and settles the most common cause before any hardware is suspected.
- 2. Put one item directly against the plate as a test — If that one freezes and the rest do not, the fault is placement, not the appliance.
- 3. Run it overnight from a known-good supply — Freezing needs uninterrupted run time; only a stable supply proves whether it can get there.
Before you open anything
Safety
Isolate first: unplug the appliance or switch off its breaker before any panel comes off, and treat a capacitor as charged after the power is gone. Ice comes off with time and a cloth, never with a blade, because what is directly behind the frost is refrigerant tubing. There are two WTW listings, WTW20 and WTW25, and nothing below distinguishes between them unless it says so.

When to call a technician
Call when the set point, the supply, the frost and the seal are all clean and the compartment still will not freeze. That combination has run out of owner checks, and what remains is the compressor module or the sealed system.
