Match the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
Show stop conditions
- A hose, tap, or connection is leaking
- The AquaStop housing or electrical valve would need to be opened or immersed
- The washer fills while powered off or internal electrical testing is required
Likely causes
- The water tap is not fully open or household water pressure is too low
- The inlet-hose filter is restricted by scale or debris
- The AquaStop or inlet hose is kinked, crushed, or installed incorrectly
- The display has been read as E29 when the model documentation uses F29 or 29
- A model-specific inlet valve, flow, wiring, or control fault prevents filling
Quick checks, in order
Confirm the exact code and E-Nr
Photograph the display and compare it with the model-specific manual before treating E29 and F29 as identical.
Open the water tap fully
Confirm a nearby tap has normal flow and that the washer supply valve is fully open.
Inspect the inlet hose and user filter
Straighten visible kinks. If the manual allows filter cleaning, turn off the tap first and never immerse an AquaStop safety valve.
Stop before valve or electrical diagnosis
If normal pressure and a clear inlet path do not solve the fault, qualified service should test the inlet system.
What happens when the 29-series code appears?
Focus first on the tap, household pressure, hose, inlet filter, and AquaStop path.
A partly closed tap, low pressure, kink, or restricted filter is the strongest external suspect.
Verify the exact E-Nr and manual. Bosch documentation commonly lists F29/29 for inlet problems, so do not assume every E29 display is equivalent.
Arrange model-specific inlet-valve, flow-sensing, wiring, or control diagnosis.
Stop and get qualified help when
- A hose, tap, or connection is leaking
- The AquaStop housing or electrical valve would need to be opened or immersed
- The washer fills while powered off or internal electrical testing is required
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does F29 mean on a Bosch washing machine?
On supported Bosch washers, F29 is grouped with F17/E17 water-inlet faults such as low water pressure, a restricted inlet filter, or a kinked supply hose.
What does E29 mean on a Bosch washing machine?
Do not assume E29 automatically equals F29. Photograph the display and check the exact E-Nr manual because Bosch code formats vary by model and market.
Can low water pressure cause Bosch F29?
Yes. Bosch guidance for supported models lists low water pressure and restricted water-supply filters or hoses among the main causes.
