The short answer
On Bosch RVY refrigerators water rarely appears where it comes from. Ice under the bottom drawer, a pool along the front, or a damp cabinet floor are all versions of one fault: the defrost drain is not draining. Chasing the puddle is what makes this repair take three visits instead of one.
What you observe on these models
- Water appears every few days rather than continuously — Defrost runs on a schedule, so drain faults are periodic rather than constant.
- Frost and water together inside the cabinet — Warm moist air getting in, condensing, and then having nowhere to drain.
- A crackling or dripping sound after the unit has been running — Normal during defrost, but worth noting alongside where the water lands.
- Wet insulation smell or a musty cabinet — Water that has been present long enough to soak something it should not.
- NEAR MISS - water only when the ice maker fills — That is the water circuit, and it is covered on the ice page for the RVY family.
Causes, most likely first on the RVY family
- Defrost drainage — First on RVY497790. If there is ice under the bottom drawer, the diagnosis is effectively made: the drain is not clearing and everything else follows from it.
- Levelling and where the water leaves — Second, and the reason the puddle is never the source. A cabinet leaning forward delivers drain water to the floor through the front, which sends people looking at the door.
- Seals and ingress — Third: every bit of warm air that gets in becomes water that has to go somewhere. Seals are cheap, checkable with a sheet of paper, and commonly the underlying cause.
- Supply line and tray — Last. Real, but the water shows at the back rather than inside, which makes it easy to separate from the rest.
Check in this order, and why
- First: clear and dry everything, then watch for a day — You are establishing the rhythm. Water that returns every few days is defrost; water that returns continuously is supply.
- Second: empty the bottom drawer and inspect — Ice or standing water under it is the drain. Thawing it with the unit off and the doors open confirms it within a day.
- Third: look behind the unit for a supply line — Where the model is plumbed, run a dry hand along the fitting and the line. Water there does not come from the drain.
- Fourth: stop at the rear panel — On the RVY family the drain runs from behind the freezer rear panel, and clearing it there is a service call rather than an owner job.
Before you open anything
Safety
Isolate the appliance before any panel comes off or any hand goes behind the cabinet; a capacitor can hold a charge after the power is off. Mop as you work rather than at the end. If water has reached an outlet or an extension lead, switch off at the breaker before touching anything, and do not restore power until everything is dry.

When to call a technician
Call when the ice under the drawer returns after being thawed, which means the blockage is upstream of where you can reach. On the RVY family the drain runs from behind the freezer rear panel, and getting to it means dismantling with the unit isolated. Seals, levelling and clearing standing water are yours.
