Quick answer
Write down the exact E or F code and the dishwasher model before trying anything, because Siemens says codes and recommended actions can differ by model and only appear on models with a digital display. For a general E01–E05 or E01–E30 technical code, switch the dishwasher off, wait a few minutes, and restart once; if it returns, close the water tap, disconnect power when the local instructions permit, and contact Siemens. E15 means the water-protection system has activated and requires the tap closed and service. E08, E14, E16, or E18 point toward water level or inlet checks; E22 points to a dirty filter; E24 or E25 points to draining. Heating, drying, circulation-pump, electronics, or repeated codes need model-specific service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Record the exact error display and the dishwasher's complete E-Nr/model number, then compare the code with the model-specific manual or Siemens error-code list.
Expected result: The display shows a digital E/F code that appears in the Siemens list, a code with extra digits, a flashing display without a code, or a symbol that the model manual explains differently.
Next step: Use the exact model documentation for the code. If the display only flashes, carefully close the door and check that no dish or accessory prevents closure; if the code remains, continue with the matching code family below.
Why this matters
Why: Siemens says error codes only appear on dishwashers with a digital display and that codes and recommended actions may not apply to every model. A flashing display can also indicate a door that is not properly closed.
-
Check 2
For E01–E05 or another general technical code, switch the dishwasher off with its normal on/off control, wait a few minutes, and restart it once while observing whether the same code returns.
Expected result: The code clears and a programme runs normally, or the same code returns immediately or after the next cycle.
Next step: If the code returns, close the water tap, switch the appliance off, disconnect power only as directed by the local manual, and contact Siemens with the exact code. Do not open the control panel.
Why this matters
Why: Siemens describes E01–E05 as likely electronics or programme-interruption faults and recommends a restart before service. A recurring code is evidence that the restart did not resolve the underlying condition.
-
Check 3
For E08, E14, E16, or E18, inspect the visible dish loading and water supply without dismantling the machine: remove a bowl that has tipped over or blocks the interior intake, confirm the tap is open, and check that the inlet hose is not kinked; check the inlet filter only if the model manual permits it.
Expected result: A tipped item or blocked intake is found, the inlet hose is bent or the tap is closed, or the visible supply path is clear but the code returns.
Next step: Correct the visible loading or hose condition and run one supervised cycle. If the code returns, close the tap and request Siemens service; do not immerse an AquaStop safety device or open the inlet valve housing.
Why this matters
Why: Siemens associates E08 with low water in the rinse bath and blocked intake, E14/E16 with filling or water-inflow faults, and E18 with a bent hose, restricted tap, or inlet filter. A repeated code after these checks points to a machine or supply fault.
-
Check 4
For E22, E23, E24, or E25, turn the dishwasher off, clean the user-accessible filter system as described in the manual, and check the visible drain hose for a kink; for E24/E25, follow only the model-approved pump-cover or blockage check.
Expected result: The filter is visibly dirty, the hose is kinked, the dishwasher drains normally after the documented check, or it still leaves water and shows the code.
Next step: Run one supervised drain or short programme after the approved check. If E23 remains, or E24/E25 returns, close the tap, switch off the appliance, and contact Siemens rather than forcing the pump cover or reaching into an unknown obstruction.
Why this matters
Why: Siemens maps E22 to a soiled or clogged filter system, E23 to a waste-water pump fault, and E24/E25 to drainage trouble that can include a blocked pump. Cleaning an accessible filter or correcting a hose kink does not prove that the pump or internal drain is healthy.
-
Check 5
Treat E09/E11/E12, E07/E10/E31, E20/E21, E26, E27, and E15 as distinct escalation paths: note the code and associated symptom, perform only the code-specific step Siemens documents, and prepare a service request when the code identifies heating, drying, circulation, water protection, or power trouble.
Expected result: The code concerns heating, drying, circulation, water in the floor tray, a water-circuit component, or low mains voltage, and it either remains after the documented single step or returns.
Next step: For E15, close the water tap and switch off the dishwasher and request service without attempting a home repair. For heating, drying, pump, water-circuit, or recurring power codes, follow the local manual and contact Siemens; do not remove panels or test live parts.
Why this matters
Why: Siemens identifies E09/E11 as heating faults, E12 as a calcified or soiled heater, E07/E10/E31 as drying faults, E20/E21 as a rinsing-circuit or circulation-pump issue, E26 as a defective water-circuit component, E27 as supply voltage, and E15 as activated water protection.

Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
The code clears after one documented restart and the dishwasher completes a cycle without a new code or abnormal water behavior.
Do this next
Monitor the next cycle and keep the recorded code. If it returns, close the tap and contact Siemens with the model number and code.
Why this path and its safety boundary
Why it matters: The event may have been a transient programme or electronics interruption, but the restart does not identify the root cause.
-
PATH 02Next step
What you see
E08, E14, E16, or E18 remains after correcting a blocked intake, closed or restricted tap, and kinked visible inlet hose.
Do this next
Close the water tap and request Siemens service. Do not dismantle the inlet valve or immerse an AquaStop device.
Why this path and its safety boundary
Why it matters: The external loading and supply checks did not restore the water-inlet condition; an internal inlet or protection fault remains possible.
-
PATH 03Next step
What you see
E22 clears after filter cleaning, or E24/E25 clears after the model-approved accessible drain check and the dishwasher drains normally.
Do this next
Keep the filters clean and monitor. If standing water, a code, or a drain-pump noise returns, stop and arrange service.
Why this path and its safety boundary
Why it matters: The observed result is consistent with an accessible filter or drain restriction, without proving that no deeper fault exists.
-
PATH 04Next step
What you see
E15 appears, water is reported in the floor tray, the machine is leaking, or E23/E26/heating/drying codes remain.
Do this next
Close the tap, switch the dishwasher off, preserve the exact code, and contact Siemens service. Do not run another cycle or open the appliance.
Why this path and its safety boundary
Why it matters: Siemens treats these patterns as water-protection, pump, circuit, heating, or drying faults that require professional diagnosis.
-
PATH 05Next step
What you see
The code returns after the appropriate check, the display shows an unlisted model-specific code, or the dishwasher trips power, smells burnt, smokes, or has exposed wiring.
Do this next
Stop using the dishwasher, disconnect power only if safe and permitted by the local instructions, and contact Siemens or a qualified technician. If there is smoke or fire, leave the area and call emergency services.
Why this path and its safety boundary
Why it matters: The fault cannot be safely narrowed from the generic code list or presents an electrical safety risk.
Helpful context
Understand the symptom
An error on a Siemens dishwasher is a diagnostic signal, not a universal diagnosis. Record the code exactly as displayed, including a leading E or F and any extra digits, then use the manual for the dishwasher's E-Nr/model. Siemens warns that its published codes and actions may not be relevant to every appliance.
The code family changes the safe next step. Water-related codes can involve the inlet, floor tray, drain, or filter. Heating, drying, circulation, and electronics codes often require service. A single restart is useful for a generic technical interruption, but a recurring code should be reported rather than repeatedly cleared.
Keep user checks external: correct loading, visible inlet hose position, accessible filters, and the appliance's normal controls. Close the water tap and switch the appliance off when Siemens directs it, and do not remove panels or attempt a water-protection, heating, pump, or electrical repair yourself.
Only after diagnosis
Potential parts
- dishwasher filter system or drain-pump assembly
Consider a replacement only if Siemens or a qualified technician confirms a failed component after distinguishing E22 filter contamination from E23/E24/E25 pump or drain faults.
Use the complete E-Nr/model and Siemens-approved parts information; do not order a pump or filter from the error code alone. - water-inlet or water-protection component
Consider this part class only when service confirms an inlet, AquaStop, or water-protection failure behind E14/E15/E16/E18 symptoms.
Water-protection and inlet components are model-specific and must be diagnosed and fitted by an appropriately qualified technician.
When checks do not resolve it
Need a professional?
Provide the complete Siemens E-Nr/model number, the exact displayed code including any extra digits, when it appears in the cycle, whether water remains inside or on the floor, the loading/inlet/filter checks performed, and whether the code cleared or returned after one restart.
Common questions
FAQ
Can I reset a Siemens dishwasher error code?
For a general technical code such as E01–E05, Siemens suggests switching off, waiting a few minutes, and restarting once. If the code returns, close the water tap, switch the appliance off, and contact Siemens with the exact code. Do not repeatedly reset a recurring fault.
What does E15 mean on a Siemens dishwasher?
Siemens says E15 or F15 means the water-protection system has activated. Close the water tap, switch off the dishwasher, and arrange Siemens service rather than trying to repair the protection system at home.
What should I check for E24?
Siemens identifies a blocked pump as one possible E24/F24 cause. Turn the dishwasher off and follow only the pump or drain check allowed by the exact model manual. If it does not resolve the code, close the tap, switch off the appliance, and contact Siemens.
Why does the same error return after I clear it?
A returning code means the one-time restart or external check did not resolve the underlying condition. Record the exact code and model, close the tap for water-related faults, and request model-specific Siemens service instead of choosing a part from the code alone.
