The short answer for these models
Ice trouble is nearly always a water problem, a temperature problem or a clearance problem, in that order. Nothing arrives, so nothing freezes; or the compartment is too warm to finish a batch; or the ice that was made is jamming somewhere on its way out. The part itself is the last thing to suspect. Where this departs from the brand-level page is the ranking. A built-under cabinet has to shed its heat through one small grille, so anything that restricts that grille shows up as a fault long before it would on a freestanding unit, so on a BUFK unit the clearance and condenser checks lead.
How this shows up
- Which form your BUFK unit is — settle this first — Check whether the unit sits in a cut-out. If it does, its heat leaves through one grille, and that grille outranks everything inside the machine.
- No ice at all, and the tray or mould is dry — The mould is dry and clean, which a failing mechanism would not manage — something upstream is not delivering.
- Ice has fused into one solid block in the bin — Melt and refreeze, which means the compartment is drifting warm between cycles or the bin is being opened too often.
Causes, most likely first on this family
- The bin, the arm or the switch is out of position — A shut-off arm resting high, or a bin not seated, tells the machine it is full and it politely stops. It is placed first on the BUFK models rather than where the brand-level page puts it, because the form of the unit decides how much this can explain — which makes the clearance and condenser checks the checks with the most to say.
- The fill valve, the mechanism or its heater — Last because everything above it is cheaper, more likely and checkable without tools, and because confirming this one means live terminals.
Check in this order, and why
- First — look at the mould and the bin — Look at the mould before you look at anything else. Dry sends you upstream to the supply and wet sends you downstream to the harvest. On these models this is the step the construction changes: read the result against the form you identified first, because the same finding means different things on the two.
- Second — confirm the compartment is properly cold — Check the compartment is genuinely cold rather than merely cool, because a marginal cabinet gives up ice first and everything else later.
Before you open anything
Safety
Drop the breaker or pull the plug first; a capacitor can hold a charge after the power is off. Keep hands out of the ice mechanism while the unit is live, because it runs to its own schedule and not to yours. Support the cabinet properly if it has to move, and clear it out first.
Where the owner job ends
The line falls where the mechanism begins. Water supply, a raised arm and a frozen bin are yours; the module, the valve and the wiring behind the panel are not. Say whether ice stopped suddenly or faded over weeks — the two point at different parts.
