- Check that the water tap feeding the dishwasher is fully open.
- Make sure the inlet hose is not kinked, twisted, or trapped behind the appliance.
- Turn off the water supply and power, then inspect and clean the inlet hose filter at the tap connection.
- Reconnect everything securely and run a fresh programme.
Kuppersbusch groups e:16 with water inlet problems. The dishwasher cannot reach the required fill level in time, which usually points to supply, pressure, hose, filter, or installation issues.
- The dishwasher stops and shows e:16 near the start of the cycle.
- Little or no water enters the tub.
- The machine may beep once, flash a warning, or drain before showing the fault.
- Water tap is closed or household pressure is too low.
- Inlet hose is kinked, twisted, trapped, or damaged.
- The inlet hose filter is clogged with debris or limescale.
- The water inlet family can also appear if the drain route or sink connection was set up incorrectly.
- Open a nearby tap and confirm there is normal water flow in the home.
- If several appliances are using water at once, test the dishwasher again when demand is lower.
- Use the pressure check from AEG support: one tap should fill a 5-litre bucket in about 30 seconds.
- Inspect the inlet hose. If it is bent, twisted, or damaged, stop and arrange repair.
- Clean the inlet hose filter, reconnect the hose, and rerun a programme.
- Check the drain hose routing and sink connection, especially if the dishwasher was recently installed or moved.
| Checkpoint | What to confirm | Good result | If it fails |
|---|---|---|---|
| Water supply | Tap is fully open and household water flow is normal | Dishwasher fills | Investigate supply or low pressure |
| Pressure check | A 5-litre bucket fills in about 30 seconds | Pressure is adequate | Water pressure is too low for normal fill |
| Inlet hose and filter | Hose is straight and inlet filter is clean | Water enters normally | Clean filter or replace damaged hose |
| Drain and install setup | Drain hose height and sink connection are correct | Programme runs normally | Correct hose routing or remove blanking plug |
- Resetting the dishwasher repeatedly without checking the water tap or inlet hose first.
- Cleaning the tub filters but forgetting the small inlet filter at the water connection.
- Overlooking installation issues after moving or fitting the machine.
- Do not continue running the dishwasher if the inlet hose is damaged.
- Do not remove hoses while the water supply is still on.
- Turn off the water supply and isolate power before removing the inlet hose or filter.
- If the hose is damaged, repair by an approved service provider is safer than continued use.
Book service if e:16 returns after the official supply, pressure, hose, filter, drain, and installation checks, or immediately if the inlet hose is damaged.
- Keep the inlet filter free from scale and debris during routine maintenance.
- Avoid trapping or sharply bending the inlet and drain hoses when pushing the dishwasher back into place.
- After installation work, recheck the sink connection and hose routing before first use.
Does e:16 always mean the water tap is closed?
No. This family also covers low pressure, a kinked hose, a blocked inlet filter, or installation issues.
Can low water pressure really trigger this fault?
Yes. If one tap cannot fill a 5-litre bucket in about 30 seconds, household pressure may be too low for the dishwasher to fill correctly.
