Bosch Dishwasher E16 Error: Water Fill Problem Solutions
Updated: February 2026
When your Bosch dishwasher displays E16 , it's signaling a water fill problem. The dishwasher expects water to reach a certain level within a specific timeframe, but this isn't happening.
Why E16 Appears
Multiple factors can trigger E16: closed water supply valve, kinked supply hose, clogged inlet valve screen, faulty water inlet valve, low water pressure, or a defective flow meter. The control board detects insufficient water and displays E16 to prevent damage from running dry.
Complete Troubleshooting Steps
- Step 1: Check the simplest cause first—ensure the water supply valve under your sink is fully open. This valve is often accidentally closed during plumbing work.
- Step 2: Turn off the water supply and disconnect the fill hose from the dishwasher. Check for kinks or compression in the hose that could restrict flow.
- Step 3: Remove the inlet valve screen (usually inside the inlet valve connection). Clean any sediment or debris with a soft brush.
- Step 4: Turn the water supply back on briefly into a bucket to verify good water pressure and flow from your house plumbing.
- Step 5: Access the inlet valve (front left area under the dishwasher) and test it electrically. The solenoid should measure 500-1500 ohms.
- Step 6: Check the flow meter (if equipped) for blockages. It's typically in the water inlet path and can become clogged with sediment.
- Step 7: Replace the inlet valve if it tests faulty or the flow meter if it's blocked and can't be cleaned.
After repairs, run a test cycle and listen for water entering the tub. The E16 error should clear once proper water flow is restored. Regular maintenance includes checking the inlet screen every six months in hard water areas.
