Bosch Dishwasher E14 — What It Means & How to Fix It
The flow meter that counts water into the machine stopped making sense, so filling can't be trusted — a reset and supply check first, then it's a sensor-level repair.
What this code means
E14 is a flow meter (filling system) fault: the small sensor that measures how much water enters the machine returned readings the control can't reconcile. Without a trustworthy count the unit won't fill confidently — the same protective logic as level-sensor faults on other brands, expressed through Bosch's metering approach.
E14 concerns measurement of incoming water; E17 is its sibling for water arriving too fast. If your symptom is no water at all, check the supply path first — a closed valve can confuse the picture.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| One-off sensor glitch after a power event | Common | Yes — power reset |
| Flow meter fouled by debris or scale | Common | No — technician job |
| Flow meter failure | Occasional | No — technician job |
| Erratic supply pressure confusing the metering | Less common | Partly — check the valve |
What you can try yourself
- Cut power for two minutes, then run a short cycle — metering glitches clear with a clean boot more often than not.
- Open the supply valve under the sink fully and confirm decent pressure at the kitchen tap; a throttled supply makes flow readings erratic.
- Check the supply line for kinks while you're under there.
- If E14 persists, the flow meter itself needs professional attention — it sits in the water path inside the unit, often near the side tank assembly on Bosch designs.
- Hard-water households: mention scale to the technician, since it's the slow killer of metering parts.
When to call a technician
- E14 returns across multiple cycles after resets with a healthy supply.
- Fills audibly start and stop in short bursts as the unit second-guesses its measurements.
- The code alternates with E15 or fill faults, which warrants professional eyes promptly.
Typical professional repair cost: Flow meter replacement typically runs $130–$250 including labor.
Frequently asked questions
What does a dishwasher flow meter actually do?
It's a tiny turbine or sensor that counts water volume as it enters, letting the machine dose water precisely per cycle instead of guessing by time. Precision is why Bosch units use so little water — and why a confused meter halts everything.
Can I descale my way out of an E14?
Routine descaling (dishwasher cleaner or citric acid cycles) is good maintenance and may help a marginal meter, but a meter that's already throwing E14 usually has scale or wear past the point a cleaner reaches. Worth one maintenance cycle before the service call, with expectations managed.
Is E14 related to the water softener system in my Bosch?
They're neighbors in the water path but separate systems. The built-in softener has its own salt and settings; the flow meter just counts. Keep the salt topped up regardless — it protects every water-touching part, the meter included.

- Bosch Dishwasher E15 Water reached the base pan under the tub and Bosch's leak protection locked the machine — sometimes a genuine leak, often a one-off spill or condensation that clears once the base dries.
- Bosch Dishwasher E24 The dishwasher can't drain properly — start with the filter, then the drain hose path, and don't skip checking that the drain pump cover is seated.
- Bosch Dishwasher E25 The drain pump itself is blocked or its cover is loose — and Bosch makes the pump cover owner-accessible, so this is one of the most fixable codes the brand throws.
- Bosch Dishwasher E09 The heating system isn't raising the water temperature — beyond one reset, the flow-through heater is a mains-voltage part that belongs to a technician.
