Error Code: E16 / E17 Difficulty: Hard
Problem: Issue with water flowing into the dishwasher or the filling system.
How to Fix E16 / E17 Error (Step-by-Step)
- For safety, switch off the power to the dishwasher at your home’s circuit breaker and close the water supply valve.
- Gently pull the dishwasher out from under the counter to access the water connections, typically on the left side.
- Locate the water inlet valve, which is where the main water supply hose connects to the appliance.
- Place a towel under the valve to catch any water, then disconnect the main supply hose, the internal dishwasher hose, and the electrical wire connectors.
- Unscrew the mounting bracket that holds the old valve in place and remove it.
- Install the new water inlet valve, making sure to securely reattach all hoses and electrical connections.
- Turn the water and power back on, then start a wash program to verify that the dishwasher fills correctly and there are no leaks.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Bosch Dishwasher
Bosch Dishwasher Error E16 / E17: Use the code, light, or symbol as the starting clue, then confirm what the dishwasher actually does before ordering parts.
- 1. Turn power off before opening panels, reaching into the sump, touching wiring, or checking the pump, heater, valve, sensor, latch, or control area.
- 2. Confirm whether the display is a normal option/status indicator or a recurring fault that interrupts filling, washing, draining, drying, locking, or controls.
- 3. Treat E16 and E17 as related water-fill clues on this grouped Bosch dishwasher page: verify supply pressure, inlet screen, hose routing, float movement, inlet valve wiring, and whether the fault appears before wash circulation begins.
- 4. Clean the filter and sump, check spray-arm movement, verify water supply, inspect the drain hose and sink connection, and correct any visible blockage before replacing parts.
- 5. Run a short test cycle and watch the exact stage where the symptom returns; the stage matters more than the label by itself.
- 6. Replace a part only after the same symptom repeats and model-specific checks point to that part category. Match any replacement to the complete Bosch dishwasher model number on the door tag.
If the issue returns after these checks, match replacement parts to the complete Bosch dishwasher model number from the appliance tag. The same display clue can point to different components depending on the exact model and when the failure appears.
