The E2 error on your Hoover Dishwasher means the appliance is not filling with water properly or the water level sensor has detected a problem. This error typically indicates a water supply issue that prevents the dishwasher from operating correctly.
| Error code | E2 |
|---|---|
| Meaning | Water fill problem or water level sensor fault |
| Severity | Medium — The dishwasher will not run until resolved |
| Time to fix | 10–30 minutes |
| Tools needed | Towels, adjustable wrench, multimeter (for advanced checks) |
What the E2 error means
The E2 error code on a Hoover dishwasher indicates that the appliance is experiencing a water fill issue. This error is triggered when the dishwasher cannot fill with water within the expected timeframe, or when the pressure switch or water level sensor detects an abnormal condition. The dishwasher's control board monitors the water intake process and will display E2 when it determines that insufficient water has entered the machine or the flow rate is too slow. This safety feature prevents the dishwasher from attempting to wash dishes without adequate water, which could damage the wash pump and heating element.
Common causes
- Water supply tap is turned off or only partially open
- Kinked or blocked inlet hose restricting water flow
- Clogged inlet valve filter screen trapping debris
- Faulty inlet valve failing to open properly
- Low water pressure in your home supply line
- Defective pressure switch or water level sensor sending incorrect readings
How to fix the E2 error
- Check the water supply tap: Locate the water supply tap under your sink or behind the dishwasher and ensure it is fully turned on. A partially closed tap will restrict water flow and trigger the E2 error. Turn the tap anticlockwise until it stops to ensure maximum flow.
- Inspect the inlet hose: Pull the dishwasher out slightly to access the back panel. Check the inlet hose for kinks, twists, or damage. Straighten any bends and ensure the hose has a clear path from the tap to the dishwasher. If the hose is damaged or split, replace it with a new one.
- Clean the inlet valve filter: Turn off the water supply tap. Disconnect the inlet hose from the back of the dishwasher using an adjustable wrench. Remove the small mesh filter screen from the inlet valve on the dishwasher. Rinse it under running water to remove debris, limescale, or sediment. Use a soft brush if necessary. Refit the filter and reconnect the hose securely.
- Test water pressure: Turn on a tap near the dishwasher and check if water flows strongly. Weak flow may indicate low household water pressure. If pressure is consistently low, contact your water supplier or a plumber. The dishwasher requires adequate pressure to fill correctly.
- Reset the dishwasher: Turn off the dishwasher and unplug it from the mains for 5 minutes. This resets the control board and clears temporary faults. Plug it back in, turn on the water supply, and run a short cycle to see if the E2 error has cleared.
- Check the inlet valve and pressure switch: If the error persists, the inlet valve may be faulty and unable to open, or the pressure switch may not be detecting water correctly. These components typically require replacement by a qualified technician if cleaning and basic checks do not resolve the issue.
FAQ
Can I use my Hoover dishwasher with the E2 error showing?
No, you cannot use the dishwasher when the E2 error is displayed. The appliance will not fill with water or start a wash cycle, as the error indicates a water supply problem that must be resolved first.
How do I know if my inlet valve is faulty?
If you have confirmed the water supply is on, the hose is not kinked, and the filter is clean, but the dishwasher still shows E2, the inlet valve may be faulty. You can test it with a multimeter to check for electrical continuity. If the valve does not open when powered, or shows no continuity, it needs replacement.
Will the E2 error clear itself after fixing the problem?
In most cases, once you have resolved the underlying water supply issue, you need to reset the dishwasher by turning it off and unplugging it for a few minutes. After reconnecting and turning on the water supply, start a new cycle. The error should clear if the problem is fixed. If E2 reappears, further investigation of the inlet valve or pressure switch may be needed.
