The answer, before the detail
No ice on Black+Decker BCD models splits cleanly in two: either the water is not getting in, or the cold is not deep enough to release a cube. Which half you are in is settled by two things you can read from the front of the cabinet — whether the dispenser still gives water, and whether the freezer is holding a safe temperature. The BCD key covers more than one build, and for this fault the difference shows in whether your unit has a water line at the back.
What you observe on these models
- No cubes at all over a full day — A total stop points at water or at the arm rather than at a slow fault.
- Small, hollow or misshapen cubes — The mould is being filled short, which is a water-supply or pressure reading rather than a cold one.
- Ice that has welded itself together — Cubes melting and refreezing, which points at the freezer temperature or at warm air reaching the bin.
- Water yes, ice no — That puts the supply, the valve and the filter behind you and moves the freezer temperature to the front.
- NEAR MISS — a leak that appeared at the same time — Deal with water on the floor before chasing ice in the bin.
Causes, ranked for the BCD build
- The freezer is not cold enough to complete a harvest — It leads because it is invisible: the machine looks well, the bin is empty, and nothing about the ice maker is at fault. A door left ajar overnight produces exactly this for a day afterwards.
- The fill tube or the fill valve is restricted, or plugged with ice — Second, and first on plumbed builds that have been moved or serviced recently: a fill tube that freezes once tends to freeze again.
- The water filter is past its life or was fitted badly — Mid-list but the cheapest to rule out, which is why it is checked early even though it is not the likeliest.
- The shut-off arm or the bin sensor is being held — It ranks low in cost and high in frequency, which is why it is checked rather than ranked.
- The ice maker module, ejector or heater has failed — Last: it is the only cause on this list that is genuinely a part failure, and every cause above it is more likely and cheaper.
Check in this order, and why
- Look at what the machine thinks the bin level is — Takes ten seconds and removes the most embarrassing cause.
- Confirm the freezer is holding a safe temperature — A freezer holds food safely at 0 °F (−18 °C) or below; a mould above harvest temperature will not release.
- Look for an ice plug at the fill tube — A visible plug explains hollow cubes and no cubes equally well, and it clears with warm water.
- Check the filter age and that it is seated — A restricted filter starves the mould; a badly seated one leaks as well.
Power off first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch and its wiring exactly as they are: it cuts the fan for a reason, and a unit that runs with the door open ices the evaporator faster than it cools the food.
Where the owner job ends
The condition is whether anything remains that you can prove from the front of the cabinet. While the dispenser gives water, the arm is free and the freezer is cold, the remaining causes are all behind the mounting plate, and that is a call. If water is not arriving at all and the shut-off valve is not obviously closed, that is also a call rather than a plumbing experiment.
