What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep running the appliance when water is visible, a leak warning is active, or water could reach wiring or controls.
- Safe next step
- Stop the cycle if safe, turn off water when appropriate, protect the floor, and avoid repeated resets until the leak source is understood.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Food residue or debris clogging the filter system
- Soiling that remains in the user-accessible filter after a cycle
- Restricted water movement through the filter assembly
Basic checks
- Observe whether standing water remains after the programme stops; if it does, do not touch the filter area until the model guidance can be followed safely.
- Disconnect power, let hot water cool, and wear suitable gloves because sharp debris may be hidden.
- Remove and rinse only the user-accessible filter parts shown in the exact model manual; after cleaning, confirm each part seats as the manual shows.
- Reinstall the filter fully, then run one monitored cycle only when no leak or standing water remains.
Reset or retry steps
- Retry once after the filter is clean, correctly seated, and the surrounding area is dry.
- Stop further retries if E22 returns or water does not drain normally.
When to call a technician
- Call Siemens service if E22 returns after safe filter cleaning and correct reinstallation.
- Arrange service if the filter is damaged, stuck, will not seat, or standing water remains after the check.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
