The short answer
On Bosch RVY refrigerators an ice maker that has stopped is usually being starved rather than broken: no water arriving, or water arriving too slowly to fill the mould. The first checks on RVY497790 are all on the supply side and none of them need a tool, which is why they come before any thought of replacing the unit.
What you observe on these models
- Production stopped after the filter was changed — Air in the line, or a filter not seated, both of which show up here first.
- It makes a batch and then stops for days — A fill valve that is marginal, or a bin switch that has stuck.
- Ice is clumping into one mass in the bin — Slow production plus a freezer that is cycling warm, so cubes fuse rather than stay loose.
- Water dispenses but no ice is made — Useful: it proves supply reaches the appliance and moves the fault past the valve.
- NEAR MISS - water pooling under the unit — That is the leak page for the RVY family, not this one.
Causes, most likely first on the RVY family
- Water supply: valve closed, line kinked or frozen — First on the RVY family. Nothing downstream matters if water is not arriving, and supply problems are free to check. A line pinched behind the cabinet after a move is the classic version.
- Filter overdue or not seated — Second. A filter at the end of its life restricts flow, which produces small hollow cubes long before it produces none at all.
- The arm, the bin switch or the unit being switched off — Third, and the finding that most often makes a service call unnecessary. These are designed to stop production and they do exactly that.
- Fill tube icing and the ice maker itself — Last. A fill tube that has frozen over repeats after every thaw, and the unit itself is the least likely of the four.
Check in this order, and why
- First: check the arm, the switch and the bin — The free check, and the one that ends a surprising share of ice calls on RVY497790.
- Second: measure the freezer — A separate thermometer, left for several hours. Food safety wants 0 F (-18 C) or below, and an ice maker struggles above it.
- Third: test the supply at the dispenser where there is one — Water that dispenses proves supply reaches the appliance; no water at all moves the fault to the household valve or the line.
- Fourth: change or reseat the filter and wait a full day — Filters restrict gradually, and a day is the shortest interval that tells you whether a change worked.
Before you open anything
Safety
Isolate the appliance before any panel comes off, and shut the household water valve before touching a line or a filter head; a capacitor can hold a charge after the power is off. Keep hands out of the harvest mechanism even with the power off, and never use a metal tool to break ice free inside the mould.

When to call a technician
Call when supply, filter, arm and freezer temperature are all confirmed good and the mould still will not fill, or when it fills and never releases. On the RVY family the fill tube and the ice maker module sit behind panels, and a fill tube that ices repeatedly usually means something upstream that an owner cannot see.
