Bosch Washer E29 Error Code — What It Means
The E29 code on a Bosch washer indicates a water inlet problem or water pressure too low condition. The machine is not detecting adequate fill during the fill cycle, usually because the water supply is restricted, the inlet path is blocked, or household pressure is insufficient.
This is not a drain fault. The error points to an issue with water coming into the machine, tied to the supply tap, inlet hose, filters, or the inlet valve itself.
Common Causes
- Closed or partially closed water tap The supply valve at the wall is not fully open or is turned off, preventing water from reaching the washer.
- Kinked or clogged inlet hose The hose is bent, crushed, or has internal sediment buildup that restricts flow.
- Blocked inlet screen or filter The mesh filter at the hose connection to the washer is clogged with debris, reducing water flow.
- Low household water pressure The building water supply pressure is too low (below at least 20 psi by some service guidelines) to fill the machine properly.
- Faulty inlet valve The solenoid valve is not opening correctly or has failed electrically or mechanically.
- Damaged or restricted inlet hose The hose has internal damage or manufacturing defects that reduce water flow even when not visibly kinked.
Step-by-Step Fix
- Turn off the washer and unplug it from power to work safely.
- Check the supply tap at the wall and confirm it is fully open in both hot and cold lines.
- Disconnect the inlet hose at the washer connection and place the end into a bucket, then turn on the supply tap to test for strong flow and separate house-supply issues from machine-side restriction.
- Inspect the inlet hose for kinks, crushing, or sediment buildup and straighten, clean, or replace the hose as needed.
- Remove and clean the inlet screen filter at the valve connection on the back of the washer if it is clogged with debris.
- Test incoming water pressure and flow at the tap. If pressure is low throughout the house, correct the building supply issue before retesting the washer.
- Test the inlet valve for proper electrical continuity and mechanical operation. If it does not open correctly or shows no continuity, replace the valve and clear the fault code by resetting the machine.
Parts Often Needed
| Part | Notes |
|---|---|
| Water inlet valve / solenoid valve | Amazon | Replace if the valve does not open mechanically or shows no electrical continuity. |
| Water inlet hose | Amazon | Use a new hose if the original is kinked, crushed, or internally clogged. |
| Inlet screen filter | Amazon | Clean or replace the mesh filter at the hose-to-valve connection if blocked by sediment. |
When to Call a Pro
Call a technician if you have verified the supply tap is open, cleaned all filters and the hose, confirmed adequate household water pressure, and the E29 code still appears. A pro can test the inlet valve electrically and mechanically, measure incoming pressure accurately, and replace the valve or diagnose pressure-switch faults that are not accessible to most homeowners. If the fault repeats after basic cleaning and hose inspection, or if you are not comfortable disconnecting water lines and testing electrical components, contact Bosch support or an authorized service provider.
