Electrolux Dishwasher error code
Electrolux Dishwasher Error A1
Electrolux Professional hood-type dishwasher A1 no-water alarm
A1 is the NO WATER alarm shown on the control panel of Electrolux Professional commercial hood-type dishwashers — documented for the WT830EAG/PW1EAG and WT850EAG/PW2EAG families — and it means the machine stopped all functions because no supply water reached it during the fill phase.
Try these first
Start here before buying a part or taking the appliance apart.
- 1Check that the water supply cock (tap) is open
Electrolux Professional NO WATER guidance starts here: confirm the shut-off cock on the supply line is fully open so water can reach the machine.
- 2Check that the water inlet filter is clean
A blocked inlet filter stops the fill. Close the supply, inspect the inlet filter, and clean it before restarting the machine.
- 3Check the minimum mains pressure
The documented hood-type families specify a dynamic supply pressure of 50–700 kPa (0.5–7 bar), measured while the tank or boiler fills. Pressure below the documented minimum can trigger A1.
A quick explanation
What does A1 mean?
Literal displayed code A1 is documented by Electrolux Professional (commercial) dishwasher documentation, not by Electrolux household dishwasher manuals. Household Electrolux dishwashers signal the same water-fill timeout differently: the residential LL-series service manual documents numbered alarm conditions flashed through the programme LEDs, where Alarm Code 1 marks the water-intake timeout — that manual does not show a literal A1 display code.
The answer you came for
How to fix Electrolux dishwasher error A1
Work through the manufacturer NO WATER checklist — supply cock, inlet filter, minimum mains pressure, then the overflow pipe — before arranging qualified commercial dishwashing service.
- 1
A1 appears — open the supply cock fully
Confirm the water shut-off cock on the supply line is fully open. A closed cock is the first listed cause of the NO WATER alarm on the documented Electrolux Professional hood-type families.
What you should see: Water is available to the machine and the fill phase can begin. - 2
Clean the water inlet filter
Close the supply, remove the inlet filter, rinse debris from it, and refit it before restarting the cycle.
What you should see: Unrestricted water flow reaches the fill valve. - 3
Confirm minimum mains pressure
Check the dynamic supply pressure on the line while the machine fills; the documented operating window is 50–700 kPa (0.5–7 bar). Raise supply-side pressure problems with the site water supply, not with parts guessing.
What you should see: Supply pressure stays inside the documented range during fill. - 4
Insert the overflow pipe correctly
Confirm the overflow pipe sits correctly in its outlet. The manufacturer lists a missing overflow among the NO WATER causes, so this check belongs in the fill alarm routine.
What you should see: The overflow path is correctly fitted before restart. - 5
When to stop and call commercial service
If A1 returns with the cock open, the inlet filter clean, pressure inside the documented window, and the overflow inserted, the fault is beyond user checks — arrange qualified Electrolux Professional service. Panels that flash a numbered LED alarm instead are household machines on a different diagnostic path: check the household tap, pressure, and hose screen, then follow the household manual.
What you should see: You stop at supported user checks and avoid unsupported part orders.
What may be causing it?
- Supply cock (tap) closed
- Dirty or blocked water inlet filter
- Mains supply pressure below the documented minimum
- Overflow pipe not inserted
These are possibilities to investigate, not proof that one part has failed.

Safety first
Disconnect power before opening panels or touching internal parts.
When to stop
- Stop if you see burned wiring, melted connectors, water near electrical parts, or a gas smell.
- Do not perform live-voltage testing unless you are trained and equipped for it.
- Use the exact model manual or service information before replacing electronic controls.
