Hoover Dishwasher Error Code E7 – Meaning and Possible Fixes
Hoover Dishwasher Error Code E7
If your Hoover dishwasher displays error code E7, it usually indicates a problem with the turbidity sensor.
Dishwashers use a turbidity sensor to measure how dirty the water becomes during a wash cycle. This sensor helps the appliance determine how long the wash programme should run and whether additional rinsing is required.
If the dishwasher cannot read the turbidity sensor correctly, it may stop the cycle and display the E7 error code.

What the E7 Error Means
Error code E7 generally indicates a fault with the turbidity sensor or the signal being sent to the control board.
The turbidity sensor monitors the clarity of the wash water. If the control system cannot detect the correct readings, the appliance may interrupt the programme.
Common Reasons This Error Appears
Faulty turbidity sensor
The sensor responsible for measuring water clarity may be damaged or malfunctioning.
Dirty sensor
Food debris, grease or limescale may cover the sensor and prevent accurate readings.
Wiring issue
Loose or damaged wiring between the sensor and the control board may interrupt the signal.
Control board fault
The dishwasher’s electronic control board may not be processing the sensor readings correctly.
Safe Checks You Can Try
Before contacting a technician, there are a few simple checks you can perform.
Clean the dishwasher filter
A blocked filter can cause dirty water to circulate and affect sensor readings.
Run a maintenance wash
Run an empty hot wash cycle with dishwasher cleaner to remove grease or residue.
Restart the dishwasher
- Turn the dishwasher off.
- Switch off power at the wall socket.
- Wait several minutes.
