# How to Fix Bosch Error E29 (No Water Flow)
Bosch Error Code E29 is a common issue that indicates a problem with the machine’s ability to draw water. Use this guide to diagnose and fix the issue, which is most often related to a faulty **Water Inlet Valve**.
***
## 1. Explanation: What Does Bosch E29 Mean?
Error E29 means the washing machine has detected that **no water, or insufficient water, is entering the drum within the maximum allowed time frame (typically 5 to 7 minutes)** after the wash cycle has started.
Essentially, the machine is calling for water, but its internal sensors (flow meter or pressure switch) are not registering the expected increase in water level.
While external supply issues (like a kinked hose or closed tap) can trigger E29, if the supply is verified, the fault lies with the component that controls the flow: the **Water Inlet Valve**.

## 2. Step-by-Step Fix: Diagnosing the E29 Error
Before attempting any internal diagnosis, **ALWAYS unplug the washing machine from the wall power outlet.**
### Phase 1: Verify External Water Supply (The Quick Checks)
These steps rule out external factors that trick the machine into thinking the valve failed.
| Step | Action | Diagnosis |
| :— | :— | :— |
| **1. Check the Taps** | Ensure the hot and cold water taps behind the machine are fully open. | If a tap is closed, open it and run a test cycle. |
| **2. Inspect the Hoses** | Check the water inlet hoses (both hot and cold, if applicable) for kinks, tight bends, or crushing. | Straighten any bent hoses. |
| **3. Check Household Pressure** | If you recently had plumbing work done, ensure the house water pressure is normal. Run a kitchen sink tap to verify flow. | If house pressure is low, the machine may not fill fast enough, triggering the E29 code. |
### Phase 2: Check the Inlet Filters
Debris or sediment in the supply water can clog the screens where the hoses connect to the machine.
1. **Turn Off the Taps:** Shut off the hot and cold water supply taps completely.
2. **Unscrew Hoses:** Carefully unscrew the water inlet hoses from the back of the Bosch machine.
3. **Inspect Filters:** Look into the inlet ports on the washing machine. You will see small mesh filter screens.
4. **Clean:** If the filters are covered in sand, scale, or sediment, carefully remove them (usually with needle-nose pliers) and clean them under running water using a small brush.
5. **Reassemble:** Replace the filters and screw the hoses back on tightly. Run a test cycle.
### Phase 3: Diagnosing the Water Inlet Valve (The Likely Culprit)
If the external supply is good and the filters are clear, the error is almost certainly the Water Inlet Valve. This electronic valve acts as a gate, opening when the machine sends it power. If it fails, water cannot pass through.
#### A. Listen for the Valve Signal
1. Plug the machine back in.
2. Start a short, cold-water cycle (the cold valve is usually used first).
3. As soon as the machine begins the cycle, listen carefully to the back of the unit.
* **Result 1: You hear a distinct “click” or “hum,” but no water flows.**
* *Diagnosis:* The machine is sending power to the valve, but the valve is mechanically stuck, blocked, or has failed internally. **The Valve needs replacement.**
* **Result 2: You hear no click, no hum, and no water flows.**
* *Diagnosis:* This could still be the valve (a totally failed solenoid), or it could be a wiring failure leading to the valve, or a failure on the main control board. However, in most consumer cases, the valve is the weak point. **Replace the Valve first.**
#### B. Advanced (Multimeter) Test
*(Perform this only if you are comfortable working with electronics)*
1. Unplug the unit and remove the top panel of the washing machine to access the valve (located where the hoses connect internally).
2. Locate the electrical connectors attached to the solenoid coils on the valve.
3. Disconnect the wiring and use a multimeter set to Ohms (Ω) to test the resistance across the terminals of the valve’s solenoid coil.
4. **Expected Reading:** Bosch valves typically read between **2,000 to 4,000 Ohms**.
5. **Fault Reading:** If the reading is infinity (OL) or zero, the solenoid coil is dead and the **Water Inlet Valve must be replaced.**

## 3. Call to Action
If you have confirmed that external supply is fine and the filters are clear, replacing the Water Inlet Valve is the next step to fixing Bosch Error E29.
