Bosch Dishwasher E17 — What It Means & How to Fix It
Water isn't getting into the dishwasher the way the filling system expects — Bosch groups E17 with E16 as an inflow problem, and a kinked or damaged inlet hose is the first thing to check.
What this code means
Bosch lists E16 and E17 together: there is an issue with water flowing into the dishwasher or with the filling system, and the water may not be able to enter. Its first check is the inlet hose — make sure it isn't kinked or damaged. Beyond the hose and the supply valve, the fault is inside the filling system and needs Bosch service.
Bosch's US error-code page describes E16 and E17 as an issue with water flowing into the dishwasher or the filling system. It sits alongside E14 (flow meter or filling fault) and E18 (water level too low) — mention any you've seen to a technician.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Inlet hose kinked, crushed or damaged | Common | Yes — inspect and straighten |
| Supply valve under the sink closed or partly closed | Common | Yes — no tools |
| One-off filling glitch | Occasional | Yes — power reset |
| Inlet valve or filling-system fault | Occasional | No — technician job |
What you can try yourself
- Check the inlet hose along its whole length and make sure it isn't kinked, crushed or damaged.
- Confirm the supply valve under the sink is fully open and that a nearby tap runs normally.
- Cut power at the breaker for two minutes, restore it and run a short cycle.
- If E17 returns with a clear hose and an open supply, stop there and contact Bosch service — the rest of the filling system is not a DIY repair.
When to call a technician
- E17 returns with the inlet hose clear and the supply valve fully open.
- The code alternates with E14, E16 or E18.
- Any sign of water under the dishwasher or an E15 leak code alongside it.
Typical professional repair cost: Inlet valve replacement typically runs $100–$200 with labor; diagnosis of the filling system starts with a standard service call.
Frequently asked questions
What does E17 mean on a Bosch dishwasher?
Bosch describes E16 and E17 as an issue with water flowing into the dishwasher or the filling system — the water may not be able to enter. Start with the inlet hose and the supply valve.
Is E17 the same as E18?
They are neighbours. Bosch lists E18 as the water level being too low or water not being pumped correctly, and E17 as a filling-system or inflow issue. The first checks — hose and supply — are the same for both.
Can I fix E17 myself?
Only the outside checks: a kinked inlet hose, a closed supply valve and a power reset. If the code comes back after those, Bosch directs owners to its customer support.

- 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.
