E7
Smeg E7 on a dishwasher: turbine flow-regulator fault
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On Smeg dishwashers such as the LVFABCR3, alarm E7 means a turbine flow-regulator malfunction (the amount of water loaded is not measured accurately) and appears at the end of the cycle. Interrupt the program, switch off and on, and start a new wash; if E7 persists, call after-sales service.
Safety first
Stop and check this first
- Some internal components remain live even when the ON/OFF button is switched off: always unplug the dishwasher from the mains or switch off the omnipolar circuit breaker and shut off the water tap before any maintenance work.
- On models fitted with an Acquastop device the water intake hose contains a solenoid valve: never cut the hose or let the valve drop into water, and leave all internal checks to an authorised technician.
Safe checks you can perform
- Reset alarm E7, switch the dishwasher off and on, and reprogram
- Check that the water intake tap is open and the hose is not kinked
- Clean the water intake filter at the inlet of the supply hose
Leave these tasks to a qualified professional
- Do not attempt this professional task: Inspect and replace the turbine flow-regulator or intake assembly
- Do not attempt this professional task: Check the sensor wiring, electronic board and reset firmware
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Inspect and replace the turbine flow-regulator or intake assembly
What they doWith the dishwasher disconnected from the mains and the water tap shut off, the authorised technician tests the turbine flow-regulator, pipes and intake valves, replacing the faulty component with an original Smeg spare part.
They must show youthe inspected turbine flow-regulator or replaced component and a completed test wash without E7.
In writingfault code E7, the turbine flow-regulator check and the part number of any component replaced.
Check the sensor wiring, electronic board and reset firmware
What they doThe authorised repairer checks the flow sensor signal to the electronic board and, if needed, applies reset software/firmware or replaces the printed circuit board using parts restricted to authorised repairers.
They must show youthe test wash cycle (45 to 70 °C) finishing cleanly with no alarm lights or E7 code.
In writingthe electronic board and sensor diagnostic results and confirmation of normal water measurement.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Reset alarm E7, switch the dishwasher off and on, and reprogram
- Who:
- you.
- How:
- open and close the door or switch the appliance off and on to reset the alarm, then program the dishwasher again and start the washing cycle as instructed for E7 in the troubleshooting table.
- Result that matters:
- checking whether the turbine flow-regulator reading clears on a fresh washing cycle.
- If the next washing cycle finishes without showing E7 at the end, no further action is needed.
- If alarm E7 appears again at the end of the cycle, move on to checking the water tap, hose and intake filter.
- Evidence to keep:
- whether E7 was shown on the display or by the first three indicator lights flashing with the fifth light on.

Check that the water intake tap is open and the hose is not kinked
- Who:
- you.
- How:
- make sure the water supply tap is fully open with normal pressure (0.5 to 9 bar) and check that the intake hose behind or under the cabinet is not kinked, crushed or pulled too tightly.
- Result that matters:
- ensuring steady water flow into the dishwasher so the turbine can measure the intake volume properly.
- If the tap was partly shut or the hose was pinched, correct it and run a wash cycle to test.
- If the tap is fully open and the hose runs smoothly, inspect the water intake filter at the hose inlet.
- Evidence to keep:
- the condition of the intake hose and whether the supply tap was fully open.

Clean the water intake filter at the inlet of the supply hose
- Who:
- you.
- How:
- unplug the dishwasher, close the water supply tap, unscrew the water intake hose (without removing the fixed filter or cutting an Acquastop hose) and clean any dirt from the inlet filter with a damp cloth or a non-metallic brush before screwing the hose back on.
- Result that matters:
- removing grit or scale at the hose inlet that can disrupt water flow measurement.
- If the intake filter was dirty and E7 does not return after cleaning, inspect the filter at least once a year.
- If the filter was clean and E7 still persists at the end of cycles, contact an authorised Service Centre.
- Evidence to keep:
- whether dirt was present on the intake hose filter and whether E7 recurred afterwards.

What it means
In Smeg's official user manual (document 19296002900, covering models such as the LVFABCR3), fault code E7 indicates a turbine flow-regulator malfunction on equipped models: the dishwasher is unable to measure the volume of water loaded accurately. On the indicator light bar, E7 is shown by the first three lights flashing, the fourth light off and the fifth light on. Unlike alarms that halt the wash immediately, E7 is displayed at the end of the cycle because the operation of the dishwasher is not harmed. Seeing E7 alone never proves that the turbine is defective.

Symptoms and causes
Probable causes · in order
- Transient inaccurate reading from the turbine flow-regulatorCommon
During water intake the turbine flow-regulator failed to measure the loaded water volume accurately on that cycle, which is why Smeg instructs you to switch off, switch back on and run the cycle again.
Evidence: Smeg lavavajillas manual de usuario 19296002900 (LVFABCR3) · Smeg dishwasher user manual 19296002900 (LVFABCR3)
- Water supply pressure outside 0.05-0.9 MPa or fouled intake filterPossible
A partly closed tap, supply pressure outside the required 0.05 to 0.9 MPa (0.5 to 9 bar) range, or dirt in the water intake hose filter disturbs flow through the turbine.
Evidence: Smeg lavavajillas manual de usuario 19296002900 (LVFABCR3) · Smeg dishwasher user manual 19296002900 (LVFABCR3)
- Persistent fault in the turbine sensor, wiring or electronic boardLess common
If alarm E7 keeps returning after resetting and reprogramming, the turbine flow-regulator, its connection or the electronic board requires inspection by an authorised technician.
