Siemens washer F26: analogue pressure sensor fault
Evidence linked to this decision
View source: Siemens washing-machine error codes and messagesRisk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
F26 means the analogue water-pressure or level signal is invalid. Use only the external checks below and stop if the code returns.
Safety first
Stop and check this first
- Stop for overfilling, continuous filling, a leak or water near electricity. Never bypass the level sensor or remove panels to reach its hose.
Safe checks you can perform
- Compare the visible water level with the cycle
- Close water and isolate power if the level is unsafe
- Record F26 or F27 and the model
Leave these tasks to a qualified professional
- Do not attempt this professional task: Test the complete level-sensing route
What a technician must be able to justify
A technician is coming
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.
Test the complete level-sensing route
What they doA technician should inspect pressure chamber, hose, analogue sensor, harness and control input against model values.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Compare the visible water level with the cycle
No special tools
Procedure
Stop immediately if the washer keeps filling, drains continuously or the visible level is clearly abnormal.
Stop for overfilling, continuous filling, a leak or water near electricity. Never bypass the level sensor or remove panels to reach its hose.

Close water and isolate power if the level is unsafe
No special tools
Procedure
Use only accessible domestic controls and a dry power point; do not enter a wet area.
Stop for overfilling, continuous filling, a leak or water near electricity. Never bypass the level sensor or remove panels to reach its hose.

Record F26 or F27 and the model
No special tools
Procedure
Photograph the full display and accessible E-Nr; do not blow into pressure tubes or run calibration modes.
Stop for overfilling, continuous filling, a leak or water near electricity. Never bypass the level sensor or remove panels to reach its hose.

What it means
Official Siemens support associates F26, E26 and E00-26 on compatible washing machines with this condition: the analogue water-pressure or level signal is invalid. This page is washer-specific; the same display on a dishwasher, dryer or another product can mean something else, and the exact E-Nr manual prevails.
Warnings and stop conditions
- Highsource verified
Stop for overfilling, continuous filling, a leak or water near electricity. Never bypass the level sensor or remove panels to reach its hose.

Symptoms and causes
Probable causes · in order
- The water-level or pressure signal is outside its valid rangeConfirmed
A pressure chamber, hose or sensor can fail to track the actual tub level.
Evidence: Siemens washing-machine error codes and messages
- The sensor connection or protected control is faultyPossible
Open circuit, short circuit, harness damage or the control input can produce the same code.
