Bosch Dishwasher E17 Error Code

Meaning: The dishwasher is not receiving enough water or is filling too slowly. The water supply may be restricted or the inlet valve may be partially blocked.

Risk: Medium. No safety hazard. The dishwasher cannot wash without adequate water. Check the water supply before calling a technician.

First safe checks:

Check that the water supply valve under the sink is fully open.
Check the inlet hose for kinks, bends, or damage.
Check the inlet hose filter screen (at the valve connection) for debris — turn off water supply first, disconnect the hose, and inspect the small mesh screen.

Call a technician if:

Water supply is fully open and the hose is clear, but E17 persists.
The inlet valve makes no sound when the cycle starts (may be electrically failed).
Water pressure is consistently low — may need a plumber rather than an appliance technician.

Common causes

Water supply valve partially closed
Kinked or restricted inlet hose
Clogged inlet hose filter screen
Low household water pressure
Defective water inlet valve (does not open fully)

Can you reset it?

Yes, with conditions. Restoring water supply usually resolves E17. If the inlet valve or hose is the issue, repair is needed.

Safe checks before calling a technician

Check that the water supply valve under the sink is fully open.
Check the inlet hose for kinks, bends, or damage.
Check the inlet hose filter screen (at the valve connection) for debris — turn off water supply first, disconnect the hose, and inspect the small mesh screen.
Make sure no other appliance is using water at the same time (can reduce pressure).
Run a cycle to see if E17 clears.

When to call a technician

Water supply is fully open and the hose is clear, but E17 persists.
The inlet valve makes no sound when the cycle starts (may be electrically failed).
Water pressure is consistently low — may need a plumber rather than an appliance technician.

FAQ

What does Bosch dishwasher E17 mean?

E17 means the dishwasher is not getting enough water. Check the supply valve, inlet hose, and hose filter screen.

Is E17 the same as E18?

Very similar. Both indicate insufficient water. E17 tends to mean restricted flow; E18 tends to mean the water level is too low. The troubleshooting steps overlap.
