Quick answer
Separate the symptom first: no water, no ice, or both. With the refrigerator operating normally, verify that the household water shutoff is open, the visible supply line is not kinked, the filter is correctly installed and not overdue, and the control panel is not locked or set to disable ice production. For an ice complaint, check that the ice bin is fully inserted and aligned and that the external chute is not visibly blocked; never reach into the ice opening. Bosch says its filter guidance and dispenser controls are model-dependent, so use the full E-Nr. manual before removing a filter, changing a setting or choosing a part. If water leaks, the line is damaged, both functions fail after the external checks, or a dispenser error returns, shut off the water as appropriate and arrange model-matched service.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Test the symptom by recording whether chilled water, cubed ice, crushed ice or both water and ice fail. Check the display for a lock indicator, disabled ice production or a displayed error, without entering a service mode.
Expected result: Only water fails, only ice fails, both selections fail, or the panel shows a lock/error state.
Next step: Use the matching branch below and record the full E-Nr. and any code before changing settings. Do not infer a failed internal part from the symptom pattern alone.
Why this matters
Why: A water-only pattern points toward the water supply/filter path; an ice-only pattern also requires the ice bin, ice production and chute to be considered. A shared failure or recurring code needs model-specific service routing.
-
Check 2
For a water or both-functions complaint, inspect the accessible household shutoff valve and visible refrigerator water line. Confirm the valve is open, the line is not kinked or crushed, and there is no leak at the visible connection. Stop and close the water supply if a connection leaks.
Expected result: The valve is closed, the line is kinked/damaged, a connection leaks, or the visible supply looks normal.
Next step: Correct only an accessible valve or gentle line-routing issue without moving a heavy refrigerator. For a damaged hose, leak or pressure problem, shut off water and use a qualified plumber or appliance service; do not perform a live electrical test.
Why this matters
Why: Bosch identifies no water supply, low pressure and a kinked line as causes of little or no dispensing. A normal visible supply does not prove that an internal valve or control is healthy.
-
Check 3
Use the full Bosch E-Nr. to identify the correct filter and compare the installation with that model's manual. If the filter is overdue, blocked, newly installed or not fully seated, follow the exact replacement procedure and the model's flush/reset instructions; do not force a cartridge.
Expected result: The filter is overdue, incorrectly installed, visibly damaged, or the dispenser improves after a correct model-matched filter service; alternatively, the filter and fit are already correct.
Next step: Use only the exact E-Nr. filter instructions. If the flow remains absent or the filter housing leaks, shut off water and arrange service rather than trying a substitute cartridge.
Why this matters
Why: Bosch's support material links filter condition to water flow and asks for the full E-Nr. before selecting a filter. Improvement after a correct filter procedure supports a water-path restriction, not a confirmed internal component failure.
-
Check 4
For an ice complaint, remove and reinsert the ice bin only as the exact manual permits, confirming it is fully seated and aligned. Look at the external chute for visible loose ice; keep fingers and tools out of the opening and never reach toward crusher blades.
Expected result: The bin was not fully aligned, ice is visibly clumped at the external opening, or the bin and opening are clear and correctly seated.
Next step: Correct the bin seating or follow the exact manual's safe clearing instruction. If clearing would require reaching into the opening, sharp objects or disassembly, stop and arrange service.
Why this matters
Why: Bosch says incorrect ice-bin alignment can prevent ice production and documents ice clumping or a blocked dispenser opening as possible ice-delivery conditions. A clear, correctly seated bin does not prove the icemaker or drive is good.
-
Check 5
Check the exact model manual for the panel-lock and ice-production controls and compare any displayed code with Bosch's official refrigeration code page. Do not assume that a similar-looking code has the same meaning on another Bosch family.
Expected result: A lock or disabled-ice setting is active, E02/E03 or another code remains, or no lock/code is present.
Next step: Change only the model-documented user setting. If a Bosch code returns or both functions remain unavailable, keep water controlled and arrange model-matched service; do not open the dispenser or control housing.
Why this matters
Why: A documented lock or disabled setting can suppress user operation. Bosch assigns E02 and E03 specific meanings on its refrigeration error page and directs service if they remain after the stated reset; no code is not evidence that a valve or board failed.
-
Check 6
Stop user diagnosis when water leaks, the line or power cord is damaged, the dispenser remains unavailable after the supply/filter/bin/control checks, an error returns, or the refrigerator itself is not cooling normally.
Expected result: The symptom clears after a documented external correction, or it persists with a leak, code, no-cooling condition or damaged connection.
Next step: Shut off the water for a leak, disconnect power only when safe for a damaged appliance, protect food as needed and arrange Bosch-authorized or qualified service. Do not remove panels, bypass switches or access internal valves.
Why this matters
Why: A corrected supply, filter, bin or setting supports a user-level condition. Persistent loss of dispensing or a water/electrical hazard requires diagnosis under the exact model's service procedure.

Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Ice is available or the ice function works, but the water dispenser has little or no flow.
Do this next
Check the visible supply and exact E-Nr. filter procedure. Shut off water and arrange service for a leak, damaged line or persistent no-flow condition.
Why this path and its safety boundary
Why it matters: Bosch's documented water-path possibilities include the shutoff valve, low pressure, a kinked line and an old or blocked filter; an internal valve is not established.
-
PATH 02Next step
What you see
Water dispenses, but cubed or crushed ice does not, or ice is present in the bin but does not exit.
Do this next
Reseat the bin and inspect only the visible opening under the exact manual. Never reach into the crusher opening; use service for a persistent blockage or failure.
Why this path and its safety boundary
Why it matters: The documented user-level possibilities include an incorrectly seated bin, clumped ice, a blocked opening, disabled ice production or a recently started/low-production icemaker; none confirms a motor or board failure.
-
PATH 03Next step
What you see
Neither water nor ice dispenses, or both stopped after installation, a filter change or a water interruption.
Do this next
Check the visible water supply, model-matched filter fit and panel state. If the line leaks, is damaged or both functions remain unavailable, shut off water and arrange service.
Why this path and its safety boundary
Why it matters: A shared supply, filter, lock/control or connection condition is plausible; the official sources do not support naming a universal dispenser valve or control board.
-
PATH 04Next step
What you see
A Bosch E02/E03 or other recurring dispenser code appears, a water leak is present, the power cord is damaged, or the refrigerator is not cooling normally.
Do this next
Stop using the affected function, shut off water for a leak and disconnect power only when safe for a damaged appliance. Arrange model-matched service without opening the dispenser or control housing.
Why this path and its safety boundary
Why it matters: The issue exceeds an external dispensing check. Bosch assigns E02/E03 meanings on its refrigeration code page and routes persistent codes to service; a leak or damaged appliance adds water/electrical risk.
Helpful context
Understand the symptom
Water and ice are separate symptoms
A Bosch refrigerator can have no water, no ice, or no dispensing from either selection. Start by noting which button or selection fails and whether the refrigerator still cools normally. Water flow points first to the supply, filter and water path; an ice-only failure also involves the ice bin, ice production and chute. Do not treat an ice-only complaint as proof that the water valve, dispenser board or icemaker has failed.
The E-Nr. controls filter and dispenser instructions
Bosch provides different refrigerator families and dispenser layouts. Its filter finder requires the full model number including the slash and two-digit suffix, and the opened manual used for examples is for a specific KFD96 family rather than this unspecified task model. Use the exact E-Nr. manual for button-lock, filter, bin and chute instructions instead of copying a sequence from another Bosch refrigerator.
Do not reach into the ice outlet
Bosch's dispenser manual warns about rotating crusher blades and says not to reach into the ice opening. The safe check is limited to the receptacle, visible chute and removable ice container as allowed by the exact manual. If a blockage cannot be cleared without tools entering the opening or panels being removed, stop and arrange service.
When checks do not resolve it
Need a professional?
Arrange service when water or ice remains unavailable after the exact model's supply, filter, bin and control checks, or when an E02/E03 or other dispenser code returns., Shut off the water for a leaking connection or damaged hose, and stop using a refrigerator with a damaged power cord or other electrical hazard., Do not reach into the ice outlet, use sharp tools in the chute, remove control or dispenser panels, bypass a lock or perform live electrical tests.

Common questions
FAQ
Why does Bosch need my full E-Nr. for a water filter?
Bosch's filter finder asks for the complete model number, including the slash and two-digit suffix, because filter and dispenser arrangements are model-dependent. Do not choose a cartridge by appearance alone.
Can I reach into the ice dispenser to clear a jam?
No. Bosch warns about rotating crusher blades and says not to reach into the ice opening. Follow only the exact model's safe clearing procedure; otherwise arrange service.
What if both water and ice stop working?
Check the accessible water supply, visible line, correctly installed model-matched filter and documented control state. If both remain unavailable or a leak/code appears, shut off water as needed and arrange service instead of guessing at an internal valve or board.
