E23
Siemens E23 on a washing machine: leak or water in the base

Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
On a Siemens washing machine, E23 means a leak or water collected in the base. Siemens says to turn off the supply tap immediately. Then unplug the machine before looking for where the water comes from.
Safety first
Stop and check this first
- Water on the floor next to a plugged in washing machine: close the tap and unplug before stepping on or drying the area.
- Do not reopen the tap or start a programme until you know where the water came from; Siemens says to turn off the supply immediately.
Safe checks you can perform
- Tap closed and power off
- Visible external connections
- Internal circuit and base check
Leave these tasks to a qualified professional
- Do not attempt this professional task: Water test after the repair

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.
Water test after the repair
What they doThe technician runs a programme that fills with water and checks that the base stays dry and E23 does not return.
They must show youa full cycle with no water in the base and no code.
In writingthe programme tested, the result and the date.
Leak location
What they doWith the machine disconnected, the technician opens the casing, checks the base and follows the water trail to the part or joint that is leaking.
They must show youthe exact leak point and the base dry after the repair.
In writingthe leaking part or joint, any replaced part with its reference, and why.
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.
Tap closed and power off
- Who:
- you, no tools.
- How:
- turn off the supply tap as soon as you see E23, as Siemens says, and unplug the machine before touching anything wet.
- Result that matters:
- no more water coming in and no power to the machine.
- If water stops reaching the floor once the tap is closed:
- the leak depends on the supply and you can keep checking safely.
- If water keeps coming out with the tap closed:
- it is water already inside; do not open the machine and call the service.
- Evidence to keep:
- a photo of the floor and the wet area before drying.

Visible external connections
- Who:
- you, with the machine unplugged and the tap closed.
- How:
- dry the floor and look, without dismantling anything, at the tap thread, the hose inlet at the back and the drain hose.
- Result that matters:
- whether any external connection drips or is damp.
- If an external connection is wet:
- the source is outside the machine; note it for the technician or installer.
- If all are dry:
- the leak is probably internal and cannot be seen without opening.
- Evidence to keep:
- a photo of each connection and of the model label.

Internal circuit and base check
- Who:
- Siemens service technician.
- How:
- opens the machine with no power and inspects the bottom tray and the internal water circuit.
- Result that matters:
- where water collects and which part it comes from.
- If the leak point is found:
- it confirms the cause of E23.
- If the base is dry and the warning stays:
- it rules out an active leak and points to the base water detection.
- Evidence to keep:
- a job sheet naming the leak point found.
Opening the casing with water inside and a mains connection is technician work. Do not do it yourself.

What it means
Siemens defines E23 as the washing machine leaking or water in the base plate. The machine watches for water building up in the bottom tray, where there should be none. The water can come from the inlet hose, the drain hose, a badly closed filter or an internal leak, and the code does not say which. So E23 does not prove that a given part is broken: only that there is water where it should not be.

Symptoms and causes
Probable causes · in order
- Leak at an external hose or connectionPossible
You can tell because there is water or dripping at the tap, the rear inlet or the drain outlet once the machine is pulled away from the wall.
Evidence: Siemens washing-machine error codes and messages
- Internal leak in the water circuitPossible
If the external connections are dry and E23 returns after drying the base, the water comes from inside and only a technician can locate it.
Evidence: Siemens washing-machine error codes and messages
- Water left in the base from an earlier leakPossible
If an earlier leak has been fixed, the base may still be wet and keep the warning on with no new dripping.
