Bosch E14: Flow Meter Not Registering Water
Medium severity
E14 fires when the flow meter on the water inlet line isn't measuring the amount of water Bosch's control board expects to see during fill.
The dishwasher sits partway through filling, sometimes with a faint trickling sound and sometimes almost silent, and the cycle won't move past that point until E14 is dealt with. It's easy to mistake for a plain no-water problem, but the meter itself is often the real point of failure rather than the water supply.
Applies to: Bosch dishwashers equipped with an electronic flow meter on the water inlet (most 300/500/800 series models).
What it means
The flow meter that measures water entering the dishwasher during fill is not registering the expected amount of flow, so the control board halts the fill and throws a fault.
The flow meter is a small reed switch that counts water passing through, not unlike a water meter on a house line — once it stops counting accurately, the control board can no longer confirm the tub filled correctly and halts rather than risk under- or over-filling.
Common causes
Reduced or unmeasured flow can originate on either side of the meter — the supply feeding it, or the switch itself:
- Faulty or worn flow meter reed switch that no longer measures flow accurately
- Clogged inlet filter mesh where the fill hose connects to the valve
- Kinked or damaged water supply line reducing flow
- Insufficient household water pressure reaching the unit
- Failing water inlet valve
What you can check yourself
Start on the supply side first, since it's the easiest thing to rule out without opening the unit up:
- Confirm the water supply valve under the sink is fully open
- Check the inlet hose for kinks or damage along its length
- Turn off the water, disconnect the fill hose at the valve, and clean out the small inlet filter screen if your model has an accessible one
- Clear the fault by holding Start for a few seconds or cycling power at the breaker, then run a cycle to see if it returns
Call a professional when
If E14 comes back within the first couple minutes of the next cycle after cleaning the inlet filter and confirming good water pressure, the flow meter or inlet valve itself has likely failed and needs replacement by a technician.
