E1
Smeg E1 on a dishwasher: Aquastop anti-flooding has tripped
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
On Smeg dishwashers such as the LVFABCR3, E1 is an Acquastop failure: the anti-flooding system has been activated, which happens with water leaks. Unplug the appliance, turn off the tap and contact Smeg after-sales service.
Safety first
Stop and check this first
- The Aquastop only works while the dishwasher is connected to the mains, so its protection is gone once unplugged: do not start the appliance again until the technician has checked it.
- The Aquastop hose contains electrical parts: Smeg says not to cut it, not to let it fall into water and, if it is damaged, to disconnect the appliance from the mains and the water supply.
Safe checks you can perform
- Cut off power and water
- Look at the Aquastop hose from outside
- Prepare the call to after-sales service
Leave these tasks to a qualified professional
- Do not attempt this professional task: Finding the leak that tripped the Aquastop

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.
Finding the leak that tripped the Aquastop
What they doThe authorised technician looks for the source of the water leak inside the appliance and checks the hose and the Aquastop device.
They must show youthe exact point of the leak, or proof that the Aquastop was faulty without a leak.
In writingthe cause found, the part replaced with its reference and the reason.
Leak free test cycle after the repair
What they doWhen finished, the technician runs a program with the appliance connected and checks that there are no leaks and E1 does not return.
They must show youa complete program without E1 and without water in the base.
In writingthe test carried out, the result, the date and the repair warranty.
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.
Cut off power and water
- Who:
- you, without opening the appliance.
- How:
- unplug the dishwasher by the plug, not the cable, or switch off the wall switch, and turn off the water intake tap. This is what Smeg's manual asks you to do in the event of a fault.
- Result that matters:
- the appliance left without power and without water intake while you wait for the technician.
- If you could cut off both:
- do not start it again until it has been inspected.
- If you cannot reach the plug or the tap:
- switch off at the wall switch or ask for help, without moving the appliance.
- Evidence to keep:
- a photo of the display or lights showing E1 before switching off, and the time of the alarm.

Look at the Aquastop hose from outside
- Who:
- you, looking without taking anything apart.
- How:
- with the appliance unplugged, look at the supply hose and the Aquastop box next to the tap. Do not cut it or let it fall into water: Smeg warns that it contains electrical parts. Also check for visible water in front of or around the appliance.
- Result that matters:
- knowing whether there is visible damage to report to the technician.
- If the hose is damaged or there is water on the floor:
- leave it unplugged with the tap off and tell the after-sales service.
- If you see nothing outside:
- that is normal, the leak is usually inside; go on to call the after-sales service.
- Evidence to keep:
- photos of the hose, the Aquastop box and the floor.

Prepare the call to after-sales service
- Who:
- you.
- How:
- find the model name on the rating label on the side of the door, as the manual explains. Note the E1 code, when it appeared and whether you saw water. For E1 the manual says to contact the after-sales service, not to reset and keep washing.
- Result that matters:
- a complete report for the authorised Smeg Technical Assistance Centre.
- If the appliance is under warranty:
- use the authorised service, as Smeg says repairs by unauthorised persons void the warranty.
- If it is out of warranty:
- still ask for a written quote before the repair.
- Evidence to keep:
- model, purchase date, photos and the service call number.

What it means
Smeg's user manual (document 19296002900, for models such as the LVFABCR3) defines E1 as an Acquastop failure: the anti-flooding system, fitted to some models only, has been activated, and it trips in case of water leaks. E1 interrupts the program immediately and the manual says to contact the after-sales service; when the Aquastop is activated, a qualified technician must find and repair the fault. Other Smeg models use another table, and the code on its own never proves which part is faulty.
Warnings and stop conditions
- Mediumeditorial warning
The Aquastop only works while the dishwasher is connected to the mains, so its protection is gone once unplugged: do not start the appliance again until the technician has checked it.
Evidence: Smeg dishwasher user manual 19296002900 (LVFABCR3)
- Highsource verified
The Aquastop hose contains electrical parts: Smeg says not to cut it, not to let it fall into water and, if it is damaged, to disconnect the appliance from the mains and the water supply.

Symptoms and causes
Probable causes · in order
- Water leak inside the applianceCommon
Smeg explains that the Aquastop system trips in case of water leaks to prevent flooding; the source of the leak has to be found by a technician.
Evidence: Smeg dishwasher user manual 19296002900 (LVFABCR3)
- Damaged Aquastop hosePossible
The Aquastop supply hose contains electrical parts; if it is damaged, Smeg says to disconnect the appliance from the mains and from the water supply.
Evidence: Smeg dishwasher user manual 19296002900 (LVFABCR3)
- Fault in the Aquastop device itselfPossible
The manual calls E1 an Acquastop failure and does not separate a real leak from a fault in the system; only the technician's inspection settles it.
