E14
Bosch Washer
Severity:What Does This Error Mean?
The E14 error on a Bosch washer indicates that the water intake flow sensor has detected a problem. The washer is not receiving the correct amount of water, or the flow sensor itself has a fault. This error can cause the machine to stop mid-cycle or refuse to start.
Affected Models
- WAW285H2UC
- WAS28460UC
- WAT28400UC
- WFVC3300UC
- Bosch front-load washers with electronic flow sensors
Common Causes
- The flow sensor inside the washer has become clogged with debris or limescale
- The water inlet valve is partially blocked or has failed
- The water supply pressure is too low to trigger the flow sensor correctly
- The inlet hose filter mesh (at the back of the machine) is clogged
- The wiring to the flow sensor is loose or damaged
How to Fix It
-
Turn off the water supply to the washing machine.
Locate the shut-off valve on the water supply hose behind the machine and turn it off before proceeding.
-
Disconnect the inlet hose from the back of the machine and check the filter mesh at the connection point.
Use needle-nose pliers to pull out the small mesh filter. Rinse it under running water to remove any debris or scale buildup.
-
Check the water supply pressure.
Bosch washers require a minimum water pressure of 0.5 bar (7 psi). If your supply pressure is low, the flow sensor may not trigger correctly.
-
Reconnect the inlet hose, turn the water supply back on, and run a test cycle.
Watch for leaks at the hose connection point before fully pushing the machine back into place.
-
If E14 returns, the flow sensor itself needs to be tested.
The flow sensor is located on the water inlet manifold inside the machine. A technician can test its output signal and replace it if needed.
When to Call a Professional
If cleaning the filters and checking the water supply doesn't resolve E14, the flow sensor or inlet valve needs professional inspection. Flow sensor replacement typically costs $100–$200 in parts and labor. Inlet valve replacement costs $120–$250.
Frequently Asked Questions
Where is the flow sensor located in a Bosch washing machine?
The flow sensor is typically mounted on the water inlet assembly inside the machine cabinet. It's a small electronic sensor with two wire leads. Accessing it requires removing the top or back panel. It's a straightforward part to replace once accessed.
Can low water pressure cause the E14 error?
Yes — Bosch washers need a minimum water supply pressure to work correctly. If pressure is too low, the flow sensor does not detect enough water movement and triggers E14. Check if other taps in the house have good pressure. If not, the issue may be with your home's water supply or a partially closed valve.
How do I clean the inlet hose filter on a Bosch washer?
Turn off the water supply, then unscrew or pull off the inlet hose from the back of the machine. You'll see a small mesh filter in the connection fitting. Pull it out carefully with needle-nose pliers. Rinse it under the tap and use an old toothbrush to clear any debris. Reinsert it firmly before reattaching the hose.
