E2
Smeg E2 on a dishwasher: safety water level has tripped
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Smeg dishwashers such as the LVFABCR3, E2 means the system that limits the water level has tripped. Interrupt the program, switch off, switch on, program it again and start the wash; if E2 returns, contact the after-sales service.
Safety first
Stop and check this first
- Smeg says some components stay live even with the on/off button set to off: unplug or switch off at the wall before cleaning the filters, and do not open any panels.
Safe checks you can perform
- Restart that Smeg gives for E2
- Rule out foam from the wrong detergent
- Level appliance and clean filters

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.
Inspection of the water level limiting system
What they doThe authorised technician checks why the safety level system trips and inspects the intake and level components before replacing any part.
They must show youthe measurement or test that locates the cause of the excess level.
In writingthe cause found, the part replaced with its reference and the reason.
Full test cycle
What they doAfter the work, the technician runs a complete program and checks that the dishwasher finishes without the E2 alarm.
They must show youa complete program without E2.
In writingthe test carried out, the result and the date.
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.
Restart that Smeg gives for E2
- Who:
- you, no tools.
- How:
- interrupt the program in progress and switch the dishwasher off. Switch it back on, program it again and start the washing cycle, as Smeg's manual says for the safety level alarm.
- Result that matters:
- knowing whether E2 was a one-off or comes back.
- If the cycle finishes without E2:
- note the date in case it happens again.
- If E2 returns:
- do not keep repeating it; go on with the usage checks and contact the after-sales service.
- Evidence to keep:
- a photo of the lights showing E2, the time and the program selected.

Rule out foam from the wrong detergent
- Who:
- you.
- How:
- check that you only use dishwasher detergent and never hand washing up liquid, which Smeg says can compromise the dishwasher's operation. Wipe off any spilled rinse aid, which the manual says can cause foam. The manual does not link these points to E2 directly.
- Result that matters:
- ruling out a usage the manual itself advises against.
- If there was washing up liquid or spilled rinse aid:
- correct it and repeat the E2 restart.
- If usage was correct:
- go on to levelling and filters.
- Evidence to keep:
- the name of the detergent used and photos of the dispenser.
Evidence: Smeg dishwasher user manual 19296002900 (LVFABCR3)
Level appliance and clean filters
- Who:
- you, with the appliance unplugged before touching the filters.
- How:
- check that the dishwasher stands level: Smeg says levelling it with the adjustable feet is essential for correct operation. Then unplug it, take out the filters at the bottom and clean them with a stiff brush under running water, as the manual explains; it warns the dishwasher cannot work with clogged filters.
- Result that matters:
- leaving the appliance in the conditions of use the manual requires before calling.
- If it was not level or the filters were dirty:
- correct it and repeat the cycle.
- If everything was fine and E2 returns:
- cut off power, turn off the tap and call the authorised Smeg Technical Assistance Centre.
- Evidence to keep:
- photos of the filters and a note of whether E2 returned after the last cycle.

What it means
Smeg's user manual (document 19296002900, for models such as the LVFABCR3) defines E2 as safety level: the system that limits the water level inside the dishwasher has been tripped. E2 interrupts the program immediately. Smeg says to interrupt the program, switch the dishwasher off, switch it back on, program it again and start the washing cycle; if the problem persists, contact the after-sales service. Other Smeg models use another table, and the code on its own never proves which part is faulty.

Symptoms and causes
Probable causes · in order
- One-off trip of the level limitPossible

Evidence: Smeg dishwasher user manual 19296002900 (LVFABCR3)
- Persistent fault in water level controlPossible
If E2 returns after repeating the cycle, Smeg refers you to the after-sales service: the level limiting system keeps tripping and the reason must be checked.
