The short answer
On a TWW refrigerator, an ice-making fault is most often the supply cutting the compressor short: freezing is the last duty a small compressor gets to, so it is the first duty lost when the controller keeps stopping it. The causes below are in likelihood order, cheapest first; working down that order costs less than starting with the part that sounds most alarming.
What you actually observe
- Frost coats the plate but the contents stay soft — Frost is an insulator; the cold is trapped on the plate instead of reaching what sits beside it.
- Drinks are cold but nothing in the compartment freezes — The classic split: refrigeration is working, freezing duty is not being reached.
- Ice forms as a thin skin and then stops — The plate is getting there and then losing it, which points at cycling rather than at a dead compressor.
- Everything freezes including what should not — NEAR MISS: that is over-cooling, a set point and thermostat question rather than this one.
- Body: No two TWW listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
Ranked causes on these TWW models
- 1. What the box has actually been asked to do — A unit set for chilled storage will hold that set point exactly and never freeze anything, and the display gives an owner no hint that the two duties differ. Usage ranks high on TWW precisely because of the spread: what is a light load for TWW115 is the whole capacity of TWW35.
- 2. Contact between the plate and what is being frozen — Air is a poor conductor and packaging is worse. Second here because it costs nothing to ask, while the cause above it explains more of what owners report on TWW.
- 3. A supply the controller keeps rejecting — Freezing is the duty that needs the longest uninterrupted run.
- 4. Frost on the plate acting as insulation — This is the cause that gets worse the longer it is ignored, and the only one on the list that clears itself completely with a defrost and a dry cloth.
Check in this order on the TWW 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
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never chip ice off a plate with a knife or a screwdriver: the tubing behind it is thin-walled, and a puncture turns a free defrost into a sealed-system repair. With six listings in the TWW table, quote the full model number when ordering anything: the differences between them are exactly the differences that matter to a parts counter.

When to call a technician
The line is the compressor and its module. A box that chills well and refuses to freeze on a clean supply, in a cool room, with a bare plate, needs a technician rather than another setting change.
